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. 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.

When I start computer it shows "Kernel Panic! - Please reboot your computer. VFS: Unable to mount root fs on unknown-block(0,0)" error.

I go to Advanced options for Kubuntu and select Kubuntu, with Linux 6.17.0-19-generic and Kubuntu, with Linux 6.17.0-19-generic(recovery mode), Kubuntu, with Linux 6.14.0-35-generic and Kubuntu, with Linux 6.14.0-35-generic(recovery mode) but go into page showing BusyBox v1.36.1 (Ubuntu 1:1.36.1-6ubuntu3.1) built-in shell (ash)

How to solve this error?

I am experiencing a boot issue with Ubuntu 26.04 Live USB.

On the same hardware, Ubuntu 24.04.3 works normally and I can enter the "Try Ubuntu" desktop without any issues. However, Ubuntu 26.04 gets stuck at the spinning loading circle after selecting "Try Ubuntu" and never reaches the desktop.

Hardware:

• CPU: Intel Alder Lake N (e.g. N97 / N305)
• GPU: Integrated Intel iGPU (i915 driver)
• Display: Tested with both HDMI and DP

Tested systems:

• Ubuntu 24.04.3: Works normally
• Ubuntu 26.04: Fails (stuck on loading spinner in Live session)

Observed behavior:

• Spinning circle appears indefinitely
• No desktop is reached

I also tried booting with "nomodeset", but the issue persists or only partially progresses.

This strongly suggests a regression in the graphics stack (kernel / i915 / mesa / GNOME shell) in Ubuntu 26.04 compared to 24.04.3 on Intel Alder Lake N hardware.

I would appreciate any guidance or workaround (kernel parameters or driver settings) to get Ubuntu 26.04 Live session working on this hardware.

Thank you.

Is there anyway to default to 96khz/24bit audio, ensure LDAC locks to High Quality (990kbps) instead of auto-scaling down?

I've tried everything, including but not limited to pipewire conf files, wireplumber conf/lua, pw-top still indicate the connection and playback at 48000 F32LE.

i currently have highly annoying audio glitches when listening to music: apps tried:

• Quodlibet
• VLC
• bashgst-launch-1.0 playbin uri=file:///home/stefan/…/Schiller__Atemlos/1__02__Schiller__Tiefblau.flac
• ffplay 1__02__Schiller__Tiefblau.flac

that all with my USB Audio Interface (iBasso DC06).

(build in laptop speakers seem to work)

for me it sounds as if the USB bus is overloaded with data / the priority for the data is to low..

this problem only showed up recently. any idea how to narrow down / analyze the problem?

I was looking for a way to access the texts from my phone on my Ubuntu 24.04 desktop, and pulse-sms seemed to be a good option. I went to the web site, downloaded the .deb package, and installed it. But when I started the app, nothing happened. I tried to start it from a terminal and got this message:

Trace/breakpoint trap (core dumped)

Pulse-sms isn't in apt or snaps, is there something I can tweak to make it work?

I would like ton configure a raid 1 array among a ssd m2 hard disk on usb and a internal nvme ssd disk.

Is it possible, and, if yes, how could I configure a raid 1 array to install ubuntu 26.04 x64 ?

I noticed that 26.04 desktop os is strictly Wayland, the bundled nvidia settings seems to lack a lot of the configurations that once existed on previous version of Ubuntu via XOrg11.

• Is there any way to get these configuratble menus, or add these settings back in manuall via key/value profile?

• Is there a way to upgrade to drivers version 610 for nvidia instead of 595 (according to nvidia website this is available but ubuntu-drivers maximum is 595), any way to upgrade?

• I heard LInux Kernel 7.10 is available any way to upgrade to this as well?

Any attempts to upgrade Nvidia drivers via .run download will essentially bricked the os, either stuck with login loop, or drivers completely not loaded resulting in single screen display,

Thanks!

I have 2 servers that I access remotely (even the BIOS) One is an AMD Ryzen and the other is an Intel Xeon. I installed Ubuntu 24 AMD version on both. I didn't have any trouble with the Xeon until I tried to update. I got in through grub and saved the critical files to the other server. I would like to reload Ubuntu for Xeon remotely without a USB. If my only option is a USB then I would have to make a 200 mile round trip.

I have Kubuntu 24.04 installed on my desktop that has an Nvidia graphics card. After attempting to resolve issues with my second monitor not being recognized, I restarted for driver changes and now I'm unable to boot into Kubuntu at all.

I have tried adjusting quiet splash to nomodeset on all available kernels and recovery mode kernels in grub. I was able to see the boot process hang on the last line in the boot process, but I'm not quite certain what that means the issue is. To clarify, none of the kernel boot options in grub work, and they all stop at the same point.

I can boot from a live CD working. The safe graphics option and change the grub file contents of the install where it's located on my drive. This was recommended based on some preliminary troubleshooting searching the web.

After that I'm not entirely certain what to do instead of completely reinstalling, which I am hesitant to do since I just got everything set up and working.

I will admit, I am not entirely familiar with how to update the grub file after changing it, or if that even is part of my issue. I've just made the switch from Windows in the last year and am not the most literate at this stuff, so I apologize in advance if I ask any follow-up questions that might be a bit silly.

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. I do not use wifi on my mobile phone. All are wired networks.

Do you have any suggestions on how to find out what is causing the problem and a possible cure?

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, thou 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 at <10%
• 2-3 hours after restart with 2 Chrome windows, email, LibreOffice Write etc running, Memory and Swap usage are both >80%

I am having a HP laptop with AMD ryzen 3 3250u processor and I installed ubuntu 26 LTS and I tried to add a hibernation device in the laptop using a swap file but what I am experiencing is that when I run the command sudo systemctl hibernate my screen goes blank for sometime and return back to the lockscreen, sometime it work for the first time and subsequent hibernate fails, I am pasting my configuration files

I am recently Installed ubuntu os. In that I can't see the wifi symbol i tried all method but result is negative. So i researched many articles shows Your wifi driver may problem change inter wifi thats like

My wifi driver ls MediaTek9702 does this not support wifi in the ubuntu. And also in additional drivers it does not show anything if loads like half hour still no output.

I was using Kubuntu, but the new LTS slowed my computer down so I'm back to an older Ubuntu LTS. I'd like to see the seconds but the same way I was able to do it in Kubuntu, by hovering over the clock, not showing them all the time on the regular clock (because that's supposed to use more computing power) so, does anyone know how to do it? Or at least showing them in the dropdown calendar instead of the top bar?

Since a couple of versions, my email folders are not sorted alphabetically anymore:

A search told me that I should have a command to automatically sort them out, but there is not such option on my version.

I thought I could sort the folders manually and place them properly sorted. Alas, it is not working. I am unable to move one folder relative to another. (that could be a personal problem, though...).

Could you please tell me how to sort them properly ? Many thanks in advance for your help.

Note: I thought they are sorted by creation time but, no, they are not.

I have a Lenovo ThinkPad X9-15 Gen 1 with Ubuntu 26.04 (Resolute Raccoon, kernel 7.0.0-22-generic) and the built-in camera is not working in any application (Firefox, GNOME Camera, etc.). I tried to replicate solutions, given for ubuntu 24, but with no avail.

Some troubleshooting

Ubuntu version: 26.04

Ubuntu sees the camera:

$ v4l2-ctl --list-devices
Intel MIPI Camera (platform:v4l2loopback-000):
    /dev/video0

What I've already tried:

• Installed oem-sutton-dana-meta, libcamhal0, linux-modules-ipu7-generic, v4l2loopback-dkms

• v4l2-ctl --list-devices shows the camera via v4l2loopback

• ipu7x.so is present in /usr/lib/libcamhal/plugins/

• pw-cli list-objects shows the camera in PipeWire

v4l2-relayd -d fails with:

CamHAL[ERR] load_camera_hal_library, failed to open PCI device
gst_parse_launch_full: assertion 'pipeline_description != NULL' failed

libcamhal-ipu7x cannot be installed due to broken dependencies:

Depends: libjsoncpp25 but it is not installable (Ubuntu 26.04 has libjsoncpp26)
Depends: libia-cca-ipu7x0
Depends: libia-log-ipu7x0
Depends: libcamhal-ipu7x-common

I am trying to use a Qualcomm QCN9274 (Compex WLE7002E25) Wi-Fi card on my x86 machine, but it's not working with the ath12k driver.

I am using the official board-2.bin from the upstream repository here.

Does anyone know what the problem is?

I’m testing Ubuntu 26.04 with Btrfs and noticed that the installer creates a flat Btrfs layout (no @ and @home subvolumes), unlike Kubuntu which sets them up by default.

This causes issues with tools like Timeshift that expect the standard @ layout.

Question:
Is there a supported or recommended way to install Ubuntu 26.04 with Btrfs using @ and @home subvolumes during installation (without manual post-install restructuring)?

Alternatively:

• Is this behavior intentional in Ubuntu’s installer?

• Are there plans to support a proper Btrfs subvolume layout like Kubuntu?

• What is the best practice for users who want snapshot-based rollback (Timeshift/Snapper) on Ubuntu?

Any official guidance or recommended workflow would be appreciated.

My friend is trying to install Ubuntu 24.04 on a new Acer desktop (very recent).

Booting from the USB drive works fine, any application or command works.

However the SSD drive is not detected anywhere: not by GParted, not by df, not by fdisk, and not by the Ubuntu installer.

For instance, sudo fdisk /dev/sda gives an error:

fdisk: cannot open /dev/sda: Invalid argument

The SSD drive works fine, since MS Windows is installed on it (as usual) and it works normally.

We tried to disable "secure boot" in the BIOS in case this is the cause, but no luck. [edit] We put secure boot back on, following comments.

2. RAID has been turned off in the BIOS (Acer support also said to do this), but it still doesn't work.

On my laptop the caps lock has a light, and for me it has reversed from Caps Lock - no light to no Caps Lock but light.

Plee

Hello folks! I've had my Latitude 7320 for a few years now and everything works out of the box with Ubuntu, except for the webcam. I've waited for years, and I'm now running 24.10 and still haven't been able to get this thing working. In this era it is very painful to have a webcam that does not work. There is at least one other person with my problem.

I've read a lot about this, and I believe that I have a MIPI ipu6 (tigerlake) architecture, which no longer uses USB so requires new packages. I see that there are many people out there running ubuntu with this type of webcam working, including official posts on the dell webpage.

Could someone please help a desperate soul here?

At the moment, I can't tell if there is a problem with loading the firmware, as it has an error message, but is followed by encouraging messages:

=> sudo dmesg | grep ipu
<snip>
[    2.857455] intel-ipu6 0000:00:05.0: Direct firmware load for intel/ipu6_fw.bin failed with error -2

[    2.870334] intel-ipu6 0000:00:05.0: Connected 1 cameras

This may be due to the fact that the Oracular linux-firmware package installs a compressed version of this file at /lib/firmware/intel/ipu/ipu6se_fw.bin.zst. I did copy a version of ipu6_fw.bin to /lib/firmware/intel/ipu6se_fw.bin for good measure but continue to see the error.

What I've done

The PPA package installation

Using this page as a guide, I added the OEM Solutions Group PPA for Intel MIPI IPU6. Here is what is listed on that PPA:

These don't appear to be installable packages:

=> sudo apt update
<snip>
Hit:7 https://ppa.launchpadcontent.net/oem-solutions-group/intel-ipu6/ubuntu oracular InRelease
All packages are up to date.    
=> sudo apt install ipu6-camera-bins
Error: Unable to locate package ipu6-camera-bins

but I can see the package details for each one of them. For example the gst-plugins-icamera package has this contents:

I can install the .deb packages listed each of them, with the exception of libipu6 which is a transitional package, so I don't believe it's a problem.

I have installed xrdp on Ubuntu 22.04 Server where I also installed ubuntu-desktop for development and testing. When one user is logged in through remote desktop, others cannot login. How to allow multiple logins (different users)?

Also, how to allow some users to login using xrdp and disable xrdp login for other users? I have four users. I want to allow accesses for two and disable access for the other two.

For ssh, it can be done using DenyUsers as answered here. Does something similar exists for xrdp?

There is one accepted answer here but I couldn't make it work.

When using the native print dialog in chromium (installed via snap) in Ubuntu 21.04, I get problems: it takes a long time to render, makes me unable to choose a page range (until the rendering is complete), and seems not to be able to work if not installed with extra permissions (with snap install --devmode chromium) (apparmor disables the access to the ppd file as can be seen from journalctl).

How do I make it use the system print dialog? (Always, no matter how it is invoked: from shell or from the menu/icon.)

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.

I installed Ubuntu 16.04 on my Acer Aspire E5-573-347G, and I have not had any problems until I needed to use bluetooth.

The Unity bluetooth menu does not allows me to use any options, as can be viewed below.

The lsusb command returns this information:

I have Ubuntu 13.04 and when I want run Vega program by ./Vega I get this message

An error has occurred. See the log file
/home/engalaabt/.eclipse/1150212041/configuration/1371636662714.log.

so what is the problem and how i can fix it ?

I use Transmission's Web Interface, but I don't feel comfortable using it remotely (outside of LAN, e.g., from a friend's house) due to the lack of any sort of encryption. The idea of broadcasting my Transmission Web Interface login details, wholly unencrypted, across the internet just doesn't appeal to me for some reason. (I'm kinda paranoid about that. I even installed a browser plugin to enable HTTPS on any site possible.)

I've heard of, and even attempted, a few of the convoluted tutorials involving lighttpd, but I haven't had any luck so far.

I just want to be able to use some sort of encryption for the Web Interface, so I can manage my torrents remotely. What do I need to do?

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?)
