My Lenovo Thinkpad x1 Carbon Gen 9, is connected to the Thinkpad docking station (https://support.lenovo.com/gb/en/solutions/PD500180) via USB-C. I've installed Synaptic repository and installed Displaylink driver, this is confirmed at the newest version.

I have 2 Full HD monitors connected to the docking station via HDMI cable and this set up works on a Windows 11 device used for work, an old HP Elitebook running Mint (can't remember version of the top of my head).

I've gone through a lot of suggested fixes online, including:

• changing boot settings
• disabling PCIe tunneling
• locked boot order (Ubuntu first, NVMe, USB listed in the order (should these be excluded)
• turned off UEFI bios updates
• used the ThinkPad emergency reset hole
• turned of IPV4 and IPV6 network stack

The next thing I am trying is another wipe of the device + new Ubuntu 24.04 boot

Any help is massively appreciated - I can also provide clearer info if needed.

I run a dual boot win11/ubuntu 24.04.4 on my pc at home because some software I use for work only works on Linux. The pc has two monitors. I left it running overnight so I could pick up my work where I left off and when I got back it told me I needed to restart for some problem (do not remember error code or anything) which is when I believe it moved to Linux kernel 6.17.0-35 and after this the mouse stopped working (wouldn’t move in response to input) and the NVIDIA drivers for my 4080 were wrong, locking the resolution to 1080x768 and failing to recognize the 2nd monitor. After updating the drivers to version 580, it recognizes both monitors and the correct resolution on Linux 0-35 but the mouse still didn’t work. Using lsusb also showed it detected the mouse was plugged in. The only previous kernel I have is 6.17.0-19-generic, where the mouse works but the drivers don’t. When I tried to install the drivers appropriate for 0-19 by changing the headers and autoinstalling the drivers they are still not correct after rebooting and selecting 0-19. Does anyone know the way to either get my mouse to work on 0-35(it also works correctly in win11 and BIOS) or the driver to work in 0-19?

On a machine running Mint, trying to install AMD GPU drivers (I know, they come pre-installed, but tell that to my system. Still getting N/A for Driver in inxi -G), keep getting the same error even after kernel upgrade and apt update/full-update/upgrade/clean/etc. The error says 2.35-0ubuntu3.13 is "to be installed" despite a number of the packages already being installed. Went to force-install the libc6 it mentioned, found out I already had a newer version of it. Command was amdgpu-install --usecase=graphics,opencl.

I'm trying to connect to a legacy Samba server here on Ubuntu 26.04 using the command: sudo mount.cifs //192.168.0.3/emanoel /mnt cifs credentials=/home/emanoel/.smbcredentials,vers=1.0,iocharset=utf8,file_mode=0777,noperm,gid=1000,uid=1000 0 0

but I can't connect. I believe it's because of SMB 1.0, giving the following error:

mount error: Server abruptly closed the connection. This can happen if the server does not support the SMB version you are trying to use. The default SMB version recently changed from SMB1 to SMB2.1 and above. Try mounting with vers=1.0.mount error(112): Host is down. Refer to the mount.cifs(8) manual page (e.g., man mount.cifs) and kernel log messages (dmesg).

I added the fstab line, it passes without error, accessing it through Nautilus works without errors, but no files from the share appear.

Everything works as expected on Ubuntu 24.04.

I am trying to set up a VDI (Virtual Desktop Infrastructure) Server, but everything I try is ineffective because Wayland and KDE require me to click on a Share in the Remote Control requested prompt. This kind of defeats the whole purpose of VDI. My users will not have access to the physical machine. They don't have an iDRAC terminal to go into the VM and click the button. And selecting to save my selection doesnt actually save anything. The next time the user logs out everything is forgotten. This has been a problem now on Wayland based OSs for over 4 years. Is there ANY solution yet. If not I will need to go back to another DE.

I should add that the built-in RDP method does not suit my use case, and please don't recommend changing my workflow that is not actually a solution to the issue.

I don't really like this answer. It would be nice to have something more native, but installing the remote desktop application (eg. RustDesk) by Flatpak, then set this special permission: flatpak permission-set kde-authorized remote-desktop com.rustdesk.RustDesk yes.

Update: Doesn't actually work. I don't get a prompt anymore, but I also don't get an image. Now I understand why some IT teams just stick with Windows, this is kind of BS.

Update 2: Going back to Windows, no matter how much I save in licensing costs, I am losing them in technician hours. Sorry (K)ubuntu. If you can't run RustDesk as a Remote Desktop without issues, then you are not ready for prime time.

For about the past week, Google Chrome has been crashing frequently and has also become noticeably slower.

I have not changed my environment or Chrome settings recently. CPU and RAM usage seem to have plenty of headroom, and I do not have an unusually large number of tabs open. In fact, I used to keep more tabs open before without any issues.

There does not seem to be any clear pattern to when the problem occurs. Chrome may freeze or crash while scrolling, but it can also happen when I am not actively interacting with the browser.

I have already tried clearing the cache and browsing history, and I also changed settings such as Memory Saver, but none of these made a noticeable difference.

I could not find any obvious error messages or signs of system instability, so I would appreciate any advice on how to investigate or fix this issue.

I found a similar unresolved issue on Ask Ubuntu.

Environment:

• OS: Ubuntu 24.04.4 LTS

• Hardware: Micro-Star International Co., Ltd. MS-7E16

• Chrome version: Version 149.0.7827.155 (Official Build) (64-bit)

I was unable to register on login.ubuntu.com. I initially received the email to verify my address, but a few seconds later I received another email stating that my account had been invalidated.

We have confirmed that there are no firewall restrictions or network blocks on our side. Is there another solution?

This app called Software Install, named gnome-software-local-file-flatpak (also sometimes shows up as just Software, named org.GNOMESoftware) autostarts at login and keeps running in the background.

It is different from App Center snap-store which comes preinstalled. I had to download Software Install from apt (probably came as gnome-software or something), and I used it to install flatpaks (also supports snaps after I turned that setting on) keeps running in the background

How do I stop Software Install / Software from running in the background? I'm using Ubuntu LTS 26.04 with GNOME 50.

Things I've already tried to no avail:

1. Turned off automatic updates, show search results from application settings
2. Turned off startup at login from System Settings > App Permissions
3. "masked" some service from Terminal following some online results, but it shows that "such a service doesn't exist, creating one". If it is worthwhile to detail this step, let me know as a comment and I'll do it.
4. Following this answer, could not delete NoDisplay=True from /etc/xdg/autostart/gnome-software-service.desktop because no such file exists.

PS: This is one thing I dislike about Ubuntu. Things change so much and so quickly - there is no persistence in construction. Is distributed disorganization really a fundamental tenet of open source? On the contrary, I think Linux has been most successful in fields where developers have built things based on a unified scheme and purpose. Too many options isn't necessarily a good thing if it comes at the cost of being worried all the time about what's going wrong in your system.

I was actively using Bluetooth, but it suddenly disappeared from my system. I've tried searching for a solution using AI, but couldn't resolve the issue. What steps should I take to fix and restore my Bluetooth connection?

I know how very contradictory that statement is, but I wanted to try it again without having to reinstall everything since I moved to KDE Plasma. But when checking what'll happen when I trry installing it alongside KDE Plasma to ensure it won't break anything, I noticed that doing apt --simulate ubuntu-desktop is fine but apt --simulate gnome wants to remove the kubuntu-desktop and kubuntu-settings-desktop packages. Is that fair to be concerned that removing those packages will mess with KDE Plasma?

Is there some way to install GNOME with the stuff that is included on native Ubuntu without it messing with KDE Plasma so that if I decide I really am sure I don't like GNOME, I can just remove it and go back to KDE Plasma like nothing happened? Also out of curiosity sake, what is the difference between ubuntu-desktop and gnome packages?

My Lenovo Yoga 9 14IRP8 often does not recognize stylus strokes from the Precision Pen 2 when drawing in (mainly vertical, but occasionally also horizontal) tablet/2-in-1 mode, as shown in the picture. I have a hard time to find the origin of this issue. It occurs in different desktop environments (KDE and GNOME) and different distributions (Fedora, Ubuntu 26.04, Ubuntu 24.04). The bugs only happen when my palm rests on the display, but persist when I disable the touchscreen via udev rule:

ACTION=="add|change", SUBSYSTEM=="input", ENV{ID_INPUT_TOUCHSCREEN}=="1", ENV{LIBINPUT_IGNORE_DEVICE}="1"

Kernel: 7.0.0-22-generic

libinput: 1.31.1

Running libinput debug-events reports ultra-short time windows where the pen is detected to be lifted and set back down. Note that the timespans seem too short for a human to lift the pen out of the proximity reach and set it back down, as illustrated by the following snippet:

event6   TABLET_TOOL_TIP              +11.969s      185.73*/103.15* tilt: -12.00 /9.00  pressure: 0.00* up

Does anyone have a similar issue? What is the most likely cause for this?

Stylus behavior in horizontal and vertical tablet mode:

BCM4322 (14e4:432b) with b43 on Ubuntu 26.04 scans WiFi networks, but authentication always times out.

System

• Computer: Mac Pro 5,1
• [wireless WiFi card: Broadcom BCM4322]
• PCI ID: 14e4:432b
• Ubuntu: 26.04 LTS
• Current kernel tested: 7.0.0-22-generic
• Previous kernel tested: 6.17.0-35-generic
• Driver: b43
• Firmware: 784.2 (2012-08-15)

Hardware is detected correctly:

lspci -nn | grep -i broadcom
0d:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4322 802.11a/b/g/n Wireless LAN Controller [14e4:432b] (rev 01)

Firmware packages installed:

dpkg -l | grep -E 'b43|bcmwl|broadcom|firmware-b43'

ii  b43-fwcutter
ii  firmware-b43-installer
ii  linux-firmware-broadcom-wireless

My WiFi adapter worked correctly in Ubuntu before.

After a system update, WiFi stopped working.

I previously managed to recover functionality with help from another AI assistant (DeepSeek), but after a later Ubuntu update to 26.04 the problem returned.

Ethernet works perfectly.

Other devices connect to the same router without problems:

• MacBook
• Linux laptops
• Android phones
• iPhones

Therefore the router itself appears to be working normally.

Symptoms

The adapter:

• Detects nearby networks correctly.
• Shows strong signal levels.
• Loads firmware correctly.
• Creates wlan0 correctly.

Example:

nmcli device wifi list

Shows all nearby networks including my own network.

However, any connection attempt fails.

NetworkManager typically reports:

Activation: (wifi) association took too long
ssid-not-found

After a failed attempt, network scanning often becomes unstable and WiFi networks disappear until NetworkManager is restarted.

Restarting NetworkManager restores network visibility.

Router

Router: Totalplay ISP router.

SSID:

Totalplay-2.4G-bc38

Interesting observation:

The same SSID appears advertised through multiple BSSIDs:

64:9D:F3:1D:BC:38  Totalplay-2.4G-bc38
64:9D:F3:1D:BC:41  Totalplay-2.4G-bc38
64:9D:F3:1D:BC:40  Totalplay-5G-bc38

I disabled and reconfigured WiFi multiple times, including router factory reset.

The issue remains.

Driver messages

At boot:

b43-phy0: Broadcom 4322 WLAN found
Loading firmware version 784.2

At some point I observed:

b43-phy0 ERROR: Fatal DMA error
This device does not support DMA on your system.
It will now be switched to PIO.

Because of this, I currently use:

cat /etc/modprobe.d/b43.conf

options b43 pio=1

Current runtime value:

cat /sys/module/b43/parameters/pio

1

Direct wpa_supplicant test

To eliminate NetworkManager from the equation I stopped NetworkManager and tested directly with wpa_supplicant.

Configuration:

network={
    ssid="Totalplay-2.4G-bc38"
    psk=<generated_psk>
    bssid=64:9D:F3:1D:BC:38
    freq_list=2412
}

This forces:

• 2.4 GHz
• channel 1
• BSSID 64:9D:F3:1D:BC:38
• WPA2-PSK

Result:

Trying to authenticate with 64:9d:f3:1d:bc:38
freq=2412 MHz

nl80211: Authentication request sent successfully

Authentication timed out

The adapter sends authentication requests but never receives a response.

The failure happens before WPA key negotiation.

Additional observations

I tested:

• Kernel 7.0.0-22-generic
• Kernel 6.17.0-35-generic

Behavior changes slightly between kernels but neither kernel successfully connects.

I also created a fresh NetworkManager profile and forced:

key-mgmt=wpa-psk
proto=rsn
pairwise=ccmp
group=ccmp

No improvement.

Question

Has anyone seen BCM4322 + b43 authentication failures like this on recent Ubuntu kernels?

Could this be:

• a known b43 regression?
• a mac80211 regression?
• a BCM4322 firmware issue?
• an incompatibility with newer Totalplay access points?
• a consequence of running the adapter in PIO mode after DMA errors?

Any suggestions for further debugging would be greatly appreciated.

I have some weird journalctl behavior.

I have two Ubuntu servers with postfix installed on them. If I run journalctl -f -u postfix@-.service on ServerA I got dynamically updated output, that shows me all postfix event: connetions, mail routing, putting messages to queue, etc. When I send some message via this server, corresponding events are shown in output almost immediately, but this not working on ServerB. On Server B it says fatal, the Postfix mail system is not running. If I run journalctl -f -u postfix@-.service I get output with a few old records and that's it, nothing else.

Why this happening like that? Is it journalctl malfunctioning, or postfix misconfigured?

This is screenshot from ServerA

This is screenshot from ServerB.

Running ubuntu 24.04.4 the wired usb ethernet asix 88179 are not working. I try so many methods but the settings-network-usb ethernet are still cannot be turned on. It is disable.

They haven't fix this problems. It work with the old ubuntu version. 22.04.

Any raspberry pi os users who encounter these problems who read this message please submit the bug reports for it.

Having lots of problems with Ubuntu 26.04 LTS and 26.10 that the wired internet connections always got disconnected. On raspberry pi 4.

The terrible is Ubuntu unattended software updates get so frustrating and annoying to use.

And lastly the snap also have a problems, cannot seems to update and install anything.

The fact of the problems is this is too way buggy and not functional to use on daily basis.

I wonder how to fix this problems.

Brave browser are flickering.

is there any commands to type on the terminals to troubleshoot the problems.

is there a way to disable the unattended updates, and the snap are not working well with updates. I had a very hard time to make it work. and it is very frustrating having an os that does not work.

so i try the daily build still the same thing nothing have change so far.

I'm on Ubuntu 26.04 (was 25.10 at original time of writing) with default everything. Until I tried xfce (briefly) then switched back.

Since then I can't run Inkscape. When I run it from the terminal I get

I think xfce might have reset the cursor theme, or I might even have done it myself, I don't recall.

But using Tweaks I've set the cursor theme to Yaru.

That theme isn't listed when I run

$ sudo update-alternatives --config x-cursor-theme
There are 7 choices for the alternative x-cursor-theme (providing /usr/share/icons/default/index.theme).

But /usr/share/icons/Yaru/cursor.theme does exist.

I have also tried running

$ dconf reset /org/gnome/desktop/interface/cursor-theme

and

$ gsettings reset org.gnome.desktop.interface cursor-theme

but no luck.

Following this question I checked and these files exist:

/usr/share/icons/Yaru/cursors/default
/usr/share/icons/Yaru/cursors/left_ptr

Any ideas what's wrong, and how I can get Inkscape running again?

After using for a period, Chrome sometimes becomes very slow and eventually freezes. Sometimes I can restart Chrome, other times I have to reboot my laptop. After many years of fault-free operation under Ubuntu, this problem has gradually become more frequent over the last few weeks.

Do you have any suggestions on how to find out what is causing the problem, and a possible cure? Please provide guidance on what diagnostic information would help to narrow down the cause.

System information:

• Chrome Version 149.0.7827.155 (Official Build) (64-bit) - [latest stable version of Google Chrome for Linux on 22-Jun-2026]
• Ubuntu 24.04.4.LTS
• Laptop: Dell Inspiron 13 7000

Diagnostic Information:

• System Monitor shows multiple errors even before slowdown, mostly of the form '/opt/google/chrome/chrome -type-renderer --crashpad-handler-pid-4808-enable-crash-reporter-.... followed by another 10 lines of alpha-numeric words and numbers. (I'm not sure if this is connected to the slowdown/freeze problem, although I did once notice a big increase in the number of processes of this type, although I did not manage to capture the details).

• CPU usage has periods of 100% usage on some of the 8 CPUs

• System Memory (8.0 GB) was 100% full just before latest crash.

• After restart, System Memory started at 20% with single tab on Chrome, increased to c. 40% with 6 tabs. swap is at <10%

• 2-3 hours after restart with 2 Chrome windows, email, LibreOffice Writer, etc. running, memory and swap usage are both >80%

I am trying to install Lubuntu 26.04 on an old computer, dual boot alongside Windows 10 on the same GPT SSD, however after a successful installation the computer boots into Windows. Grub does not appear, and I have no option to boot into Linux.

The motherboard is a Hybrid EFI Gigabyte 78LMT. Apparently it can make dual booting very tricky, but I lack the technical knowledge to understand details like these. Windows is installed in UEFI mode, but I can only boot from USB in legacy mode; hence, Lubuntu is not installed in EFI mode. The inability to boot USB in EFI mode is a known issue with this motherboard and its "hybrid EFI" technology.

Specs:

• Motherboard: Gigabyte GA-78LMT-USB3 Rev. 5.0

• CPU: AMD FX-8350 (8-core, 125W, AM3+)

• RAM: 8GB DDR3 1600 MHz (2×4 GB)

• GPU: AMD Radeon HD 7750 1GB GDDR5

I have tried this solution but boot-repair gives the following error:"The current session is in Bios-compatibility mode". I cannot setup the BIOS to boot USB in EFI mode, the option exists for CD/DVD only, as explained here:

Although Gigabyte's Hybrid EFI contains a full-fledged EFI implementation from an OS's perspective, the firmware setup utility provides almost no options to help you use this functionality. Specifically, only one firmware option, entitled "EFI CD/DVD Boot Option," on the "Advanced BIOS Features" menu, relates to this feature.

In another question, someone tried to install from CD, apparently without success. I have no CD/DVD drive to test this option.

I cannot find any UEFI settings to select Ubuntu as the default operating system to boot either; thus, it seems this solution will not work: no UEFI settings.

I can choose from which disk to boot; Windows and Ubuntu are on the same SDD. I have also an old HDD I use for backup attached to the motherboard; perhaps installing GRUB on it could be a solution?

GNOME Activities Overview workspace thumbnails begin flickering after about 10 minutes of uptime on Ubuntu 26.04 LTS with GNOME Shell 50.1 running on Wayland and Intel Alder Lake-N integrated graphics (i915 driver).

System:

• Ubuntu 26.04 (upgraded from 24.04)
• GNOME Shell 50.1 / Mutter 50.1
• Wayland session (no Xorg session available)
• Intel Alder Lake-N UHD Graphics (i915 driver)
• Three displays (all 1920×1080 @ 60Hz)

Symptoms:

• After about 10 minutes of uptime, GNOME Activities Overview becomes visually corrupted.
• Specifically, workspace thumbnails flicker immediately upon entering Overview (Super key or hot corner).
• The flickering is limited to Overview workspace thumbnails and GNOME top bar. Normal desktop, application windows remain stable and unaffected.
• Exiting Overview immediately returns the desktop to normal. Logging out and back in resolves the issue temporarily, but it returns in a few minutes, rebooting it returns after 10 or 15 minutes. No GPU resets, hangs, or DRM errors appear in journalctl.

I’ve tried:

• Kernel parameter: intel_idle.max_cstate=1 Appears to delay or partially change the symptoms, but the issue still occurs.
• Kernel parameter: i915.enable_dc=0 Initially seemed to reduce symptoms, but the issue still returned.
• Tested different kernels (including older kernel) No change in long-term behavior.
• Disabled a couple of third-party GNOME extensions (still using default Ubuntu extensions).

Observations:

• The issue does not affect application rendering or the desktop outside of Activities Overview.
• It appears only after extended uptime (hours), not immediately after login. - Update - this occurs sporadically, sometimes 10 minutes and some boots it would take a few hours.
• The issue is reproducible across reboots and kernel versions.
• No relevant errors in journalctl related to i915, DRM, or GPU resets.

Question:

Has anyone seen GNOME Activities Overview workspace thumbnail flickering or corruption on GNOME Shell 50 / Mutter 50 under Wayland, particularly on Intel integrated graphics? Are there known issues, workarounds, or logs that I should investigate further?

Update:

I performed additional testing and found a significant correlation with monitor configuration.

With my original multi-monitor setup (2 ASUS monitors + 1 TCL TV), GNOME Shell produced thousands of repeated errors:

gbm_surface_lock_front_buffer failed Failed to query buffer age, got error 3003

These sessions also exhibited Activities Overview flickering, top-panel flickering, and occasional window-edge artifacts.

I have now tested the system with a single display only (different display: Sony TV over HDMI) and the issue has not reproduced. There is no visible flickering, no rendering corruption, and:

journalctl -b | grep -c "gbm_surface_lock_front_buffer failed" 0

journalctl -b | grep -c "Failed to query buffer age" 0

The issue also reproduced across multiple kernels, including a newer mainline kernel Linux 7.0.12-070012-generic, which makes a pure kernel/i915 explanation seem less likely. Using this mainline kernel the symptoms also started appearing after roughly 10 minutes rather than a few hours.

At this point, the strongest lead appears to be a GNOME Shell/Mutter multi-monitor rendering issue, or an interaction involving multiple outputs.

Update (June 22nd):

The issue now consistently appears ~10 minutes after boot (earlier testing likely just didn’t run under full load).

The “unplug/replug” suggestion didn’t help, but it led to a reliable workaround: boot with only the DP 4K display connected, wait a few minutes, then connect the first HDMI display, wait again, then connect the second HDMI display. This results in a stable session and has provided ~20 hours of uptime without flickering or GBM errors.

I’ve reverted all system tweaks and returned displays to:

DP-1: 3840×2160 @ 60Hz, 200% scaling HDMI-1: 3840×2160 @ 60Hz, 200% scaling HDMI-2: 1920×1080 @ 60Hz, 100% scaling

(Previous all at 1080p configuration was part of testing.)

Driver and desktop tests:

Tried Intel Xe driver → same issue Tried KDE Plasma and Budgie → no flickering/GBM errors, but DP 4K display stayed black until forcing 30Hz via CLI (GUI wouldn’t allow it), so I reverted back to GNOME

Current conclusion: GNOME + Intel display stack on this hardware appears unstable only in full 3-display configurations. Any 1–2 display combination is stable for long periods, but stability on 3 displays only occurs with the staged hotplug sequence (DP first, then HDMIs). Adding DP last reliably triggers the issue.

At this point, this is a workaround rather than a fix.

I have a test system with two physical disks. I'm trying to recreate a setup I used to use years ago where I could span volumes across said physical disks. I never considered it a complicated setup but, I can't seem to duplicate it with ubiquity. When I did this last, the installer was still text based and that doesn't seem to be an option these days. I attempted the following within the Ubuntu 26.04 Live environment.

My two physical drives, in this example, are /dev/sda & /dev/sdb. I went looking for the equivalent commands and I think I got close. What I did is below:

1. I created partitions for the EFI boot stuff and LVM: sudo fdisk /dev/sda

   1. Made one primary partition, about 1GB

      1. Flagged it ef for EFI (/dev/sda1)

   2. Made a logical/extended partition for the rest of the drive

      1. Flagged it 8e for Linux LVM (/dev/sda2)

2. I created created one logical/extended on the second drive: sudo fdisk /dev/sdb

   1. Flagged it 8e for Linux LVM (/dev/sdb1).

3. I then used LUKS to encrypt the partitions that will be used for the system:

   1. sudo cryptsetup open /dev/sda2 crypt_drive1 && sudo cryptsetup open /dev/sdb1 crypt_drive2

4. I then opened those encrypted partitions:

   1. sudo cryptsetup open /dev/sda2 crypt_drive1 && sudo cryptsetup open /dev/sdb1 crypt_drive2

5. I then set up a volume group with some logical volumes:

   1. sudo pvcreate /dev/mapper/crypt_drive1 /dev/mapper/crypt_drive2

   2. sudo vgcreate vg_system /dev/mapper/crypt_drive1 /dev/mapper/crypt_drive2

   3. sudo lvcreate -L 8G -n lv_swap vg_system

   4. sudo lvcreate -l 100%FREE -n lv_root vg_system

At this point, I figured I was good to go so I fired up the installer wizard and tried to run through the installer. When I got to the partition setup, I selected the option for a manual setup and expected to see my logical volumes available but didn't. I was able to select /dev/sda as my boot device and it set dev/sda1 as the boot partition but, it's not showing the logical volume stuff. Below, is a screenshot of where I'm stuck. I'm sure I missed a step. Where did I go wrong?

Starting an installation of Ubuntu 26.04 with full disk wipe using the graphical installer, I have an installation stuck at rsync command for 30+ minutes after an error.

rsync connection closed:

Is there any way to proceed?

The Problem

Wi-Fi works when it wishes to. Sometimes it works fine despite heavy downloads and fast speed and Bluetooth enabled. Sometimes it goes on strike after loading a couple of tabs in the browser. It may stop working soon after boot, after many minutes, or hours, or not at all. The problem presents itself almost periodical. Usually, It starts having problems when I am using both wifi and bluetooth at the same time. Until now it appeared thrice, and it solved "itself" twice with an update after a number of months between 1 and 4, without any information on what caused or fixed the issue.

Symptoms

On the widget on the top right the wifi cannot detect networks, and if wifi is turned off it cannot be turned on. Sometimes, on boot the wifi voice on the drop-down menu is not even showing. lshw -c network shows network UNCLAIMED.

Running BIOS diagnostics detects no issue.

Latest diagnostics (23/06/2026)

• dmesg ` https://paste.ubuntu.com/p/xJHrD2cr2G/
• ./wireless-info output https://paste.ubuntu.com/p/bVQqnVc7Pj/

What I tried

I've tried reinstalling linux-firmware, NetworkManager restarts, to no avail. After a while, something randomly breaks, and it is especially frustrating as I have no easy access to ethernet cables.
Using older kernels did not work either.
I found that, SOMETIMES, flea reset OR messing with unimportant BIOS options, booting the os, rebooting and changing BIOS options again sometimes allows me for sustained network access (a suggestion I found browsing for solutions)... maybe this last one is not effective, I don't know how to check.

Technical Information

Hardware information

No dual boot. The machine came with Ubuntu22.04.1 preinstalled. I use it for work, programming, scientific computation, watching videos, and gaming. The original kernel for this Dell was an OEM kernel listed as 6.1.0-1013.13_oem. I have installed HWE kernels and I am currently running the latest HWE available. It worked perfectly for more than 1 year, even after I upgraded the OS to Ubuntu24. To try to fix the issue, I performed a factory reset, and it is back to 22.

Diagnostics

I performed hardware and software diagnostics.

Hardware Diagnostics

I performed diagnostics from the manifacturer's BIOS menu, using quick test and advanced test: all passed

Software Diagnostics

I created wifi logs using the wireless-info script I found here in askubuntu: wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info

When wifi is NOT working

The following logs were created using ./wireless-info when the wifi crashed, and no LAN network was attached. https://paste.ubuntu.com/p/bVQqnVc7Pj/ (updated on 23/06/2026) ~https://paste.ubuntu.com/p/T7Pv3NMnXc/~

When wifi is working

The following logs were created when the wifi is working just after boot (and it crashes later) using the same script. https://paste.ubuntu.com/p/td4gSKsJFy/ (updated on 23/06/2026) https://paste.ubuntu.com/p/SGFcT7dXyB/ (updated on 24/12/2025)

Final Notes and Updates

I welcome any advice on what to do when it will break, or why does it do that, additional diagnostics, readings, tools to install, etc. are more than welcome. E.g. I have just installed net-tools and iw, and I have read conflicting and old advice suggesting to install backport-iwlwifi-dkms.

Also, the guide in https://help.ubuntu.com/community/WifiDocs/WirelessTroubleShootingGuide seems to be somewhat helpful with understanding the diagnostics. Sadly, it does not provide any help in dealing with the problem I am experiencing.

edit Update: 24/12/2025

The problem manifested again. All I did was

• deactivated airplane mode
• connected to my cellphone hotspot
• updated snap
• apt update
  • sudo apt update
  • apt list --upgradeble (no hardware, security, or system updates, only software-related updates unrelated to wifi)
  • sudo apt upgrade After I lost wifi in the middle of the update, the wifi disappeared altogether.

What I tried and did not work:

• rebooting;
• disabling secure boot
• using different kernel versions;
• Changing BIOS options;
• nmcli networking off && nmcli networking on;
• nmcli radio wifi off && nmcli radio wifi on.

What did work for a bit:

• flea reset.

The diagnostics were updated in this edit. This is the old diagnostic of the wifi when it is not working: https://paste.ubuntu.com/p/xnYs8dGp5W/
I am keeping it for reference, but it lacks iw outputs.

edit Update: 23/06/2026

I may have made some progress.

The problem did not appear for some months after some updates. However, with the latest update the issue presented itself again.

I noticed that many error logs show "microcode" sudo dmesg | grep -iE 'microcode' [ 391.120843] iwlwifi 0000:00:14.3: Microcode SW error detected. Restarting 0x0.

A more complete output of dmesg is found here: https://paste.ubuntu.com/p/xJHrD2cr2G/

I tried a couple of workarounds:

• sudo iwconfig wlp0s20f3 power off and sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf and reboot, as suggested by @Jeremy31. Sadly, it did not work.
• adding the following settings to /etc/modprobe.d/iwlwifi.conf options iwlwif 11n_disable=1 options iwlwifi swcrypto=0 options iwlwifi power_save=0 options iwlwifi uapsd_disable=1 as explained in What is "options iwlwifi 11n_disable=1" in WiFi setting? and https://bbs.archlinux.org/viewtopic.php?id=254766

This last fix seems to solve the issue, and without any external fix. In the next days I'll try to isolate the specific options that make the iwlwifi work, to isolate which option causes the iwlwifi module to crash.

The diagnostics and the problem description were updated and cleaned in this edit.

P.S.

I find it curious that a (possibly) working fix to this issue was found in an Arch Linux forum.

First of all, I'm not an experienced user so please be as clear as possible in all answers. I recently installed Ubuntu 22.04 on a new HP Victus laptop (This one except with Intel Core i7-12700H and GeForce RTX 3050 Ti). The wifi was working fine. I was not messing with any settings, it just suddenly disconnected and now it says "no wifi adapter found" in settings. I have already tried some solutions from similar questions but nothing works. I'm now online using a tethered android phone.

The wifi adapter does not show up using 'sudo lshw -C network':

I hope I haven't messed things up even further trying things from other questions without knowing exactly what I was doing (there are so many, i've lost track of everything I've done). I will use this computer for studying and I've spent a lot of time setting up all the software I will need, CUDA for molecular dynamics simulations and onedrive etc. So I would really like to avoid a fresh install if possible. Thank you in advance for your help.

I'm using Ubuntu 20.04 focal fossa.

I'm trying to install a package that depends on libc6=<2.33 or above. However, focal repositories only have version 2.31, which is causing dependency troubles:

Depends: libc6 (>= 2.34) but 2.31-0ubuntu9.2 is to be installed

Is there any way I can install libc6 2.34 or above on Ubuntu 20.04 focal?

LibreOffice does not seem to have an inbuilt voice type feature. Is there any way to enable voice typing in LibreOffice?

If not, is there any other free and open source software with which I can voice type in LibreOffice?

I am using Ubuntu 24.04.

While messing around with wine and learning how to use it I tried to start a game with it (genshin impact), as expected the game doesn't work very well (it simply crash) but I found in the logs some error I would like to fix. 00c9:err:module:import_dll Library WDFLDR.SYS (which is needed by L"C:\\users\\galyfray\\Temp\\mhyprot2.sys") not found After some research it seems to be a very important lib in windows and messing with it leads to BSOD but nothing about wine.
I'm running Ubuntu 20.04 with wine 5.0.2 wich is setup to emulate like a Win10. The missing lib isn't avalable with winetricks.

I have also several others error I put them bellow if some of them are related to my problem

I hope that someone know how to fiw it I will continue my research and update if I found anything. EDIT : I'm using WINEARCH=win64 (the game is in 64 bit as far as know it shouldn't be a problem) and a 64 bit WINEPREFIX

EDIT 2: dowloading and placing the missing file where it should be in the window file tree doesn't solve the problem

I used this command to install pwgen:

sudo snap install pwgen-tyhicks

But I can't find out how to use it. So I want to uninstall it. How do I uninstall it?

After installing Lubuntu, I got the No bootable device error, and after searching the net for a solution, tried to set the Select an UEFI file as trusted for executing option as instructed, but it does not show me any drives. The Information screen in the bios setup shows me HDD0, but the Security screen that's supposed to let me select the efi file shows nothing, unless I insert the USB. I set the supervisor password after installation, and I thought this may be a reason, and installed it all over again. But it's still showing me nothing. I am sure the installation was done on the hard disk because all previous boot options are gone (as I wanted).

What can be the problem? P.S. I am new to Linux.

Edit:

I have tried turning off secure boot, but it did not help.

I have checked and there is one partition with file system lvm2 pv with flags boot and lvm.

It's an Acer Aspire E 15 (E5-575-50RM) that came with Linpus and had no GUI. I have installed lubuntu-17.10.1-desktop-amd64.

I did not use any software to create the USB since my Windows XP is damaged and files are missing or corrupted. I used EaseUS Partition Master to format the USB as FAT32 and then copied the extracted ISO files to it, then marked the single partition as active.

I have a fresh install of Ubuntu 12.04.1 LTS an a number of servers.

I have not added any cron jobs or edited my crontab on those servers, however, at around the same time for each machine, I get a 75% CPU spike and the following info in my syslog at the time of the spike:

CRON[8380]: (CRON) info (No MTA installed, discarding output)

I have mono-complete installed and am running a service stack webserver.

What is the best way for me to stop this from happening? I would like to be able to remove the CPU spike.

I need to view a .pub file. How can I view the file or convert it to a more mainstream format (such as a PDF?)
