I'm running Ubuntu 26.04 LTS, 64-bit, Linux 7.0.0-15-generic, gnome version 50.

And using an NVIDIA GeForce RTX 3060.

I downloaded and installed the new Ubuntu, onto a newer computer. Installed Steam, and was met with the message:

"32-bit NVIDIA driver files were not found on your host system. It's best you install them for the best experience."

It then gives some terminal commands.

sudo dpkg --add-architecture i386
sudo apt update
sudo apt install libnvidia-gl-595:i386

Enter the commands in that order and it gives me this response:

I'm a new user to Ubuntu 26.04. I'm using Ubuntu to both serve a data drive to my home network as well as controlling Ubuntu (so I can learn more about it) via remote control from the MacBook. It works very nicely when it's working, but anytime I reboot I must connect a keyboard and mouse to the Ubuntu PC and manually go into System/Remote Desktop and select UNLOCK and enter my password for the system to allow remote connection on the Mac. I should mention I'm using a Mac application now called "Windows App" to initiate that remote connection.

What I really would prefer is to just reboot and be able to connect the remote desktop. The Ubuntu PC already auto logs in, but not the RMD.

I use Ubuntu Desktop 25.10 and want to upgrade to Ubuntu 26.04
I have updated + upgraded my packages multiple times, yet the same error occurrs:

Reading cache
Distribution data outdated 
Please ensure all package updates are installed, and then try again. 
=== Command detached from window (Wed May 20 22:51:41 2026) ===

I have a Ubuntu SO 24.04 LTS and it has a RTL8192EE PCIe wireless network adapter.

When I updated to 26.04 from terminal using sudo do-release-update -d my wireless adapter stopped working, and I have no clue why. I wonder that the drivers from that adapter are updated just for Windows, because when you visit the drivers website (https://www.realtek.com/Download/List?cate_id=672&menu_id=297) it only shows the Windows drivers, not Linux or others.

I tried rescanning the drivers and making rm to reinstall them, viewing Secure Boot, rfkill bloq, NetworkManager restart.

Is changing the PCIe Adapter an option? Is there other way to solve it?

Starting 25.10 Ubuntu (Gnome) installer could install alongside Windows even with Bitlocker ON, if there is a freespace already.

But today when I installed 26.04, there was no Grub installed in EFI partition (as I checked later through Windows). So there was no way to boot into the Ubuntu, the Bitlocker screen came up. I didn't face this issue with 25.10 when installing alongside Windows with Bitlocker ON.

Should I try Kubuntu 26.04 now? Although they still have Calamares, not Flutter installer, can it work?

This morning I booted my Ubuntu 24.04 and internet connection was gone! Tried some Network restarts and found NetworkManager couldn't start. Some tutorials tell me to get dhclient, but to get that and other drivers and system updates, I need internet connection!

I changed the settings on the systemd file on NM and lowered the amount of seconds to try to get it to stop stopping NM but it's still the same

I'm new and so my knowledge is based on copy and pasting what I find on the internet.

I need my computer. Tried adding wifi manually on the prompt, ancoring from my phone. it's been 5 hours of browsing the Internet for solutions that require me to have internet connection to install the commands.

I am at a complete loss at this point in time. No matter what I do, upgrading to 26.04 was a mistake. Had nothing but gui issues (using a gtx 1660 ti), apps weren't working in the slightest. So I went back to 24.04.

Anyways the problem(s) at hand.

tldr; Having all the problems in the title, but not sure how to solve them. Seeking help!

The force reboot keeps happening. For no reason, I would be in the middle of a video, maybe I'm in the middle of writing code on visual studio code. Maybe I am doing my art design or whatever. Ubuntu will force restart my computer for no reason. Doesn't ask, just does. This is a reoccurring problem I've been having with ubuntu.

I have an xp pen artist 12 pro external drawing monitor. Sometimes when I am using it or it's connected, the display will stop working. Likewise it flickers on and off.

Apps flickers. Quite often actually. Between steam. Videos or websites on Firefox, they flicker at a constant rate. Probably happens about 10x a day in a 8 hour span of being on this computer.

The pointers and keyboards will randomly stop working. To the point that logging out does nothing. I have to force reboot. Wondering if this relates to being with a laptop and having hooked up devices. But shouldn't make a difference.

Now my question at hand is... How do I solve these issues? I have been trying different work arounds. Different drivers, upgrading ubuntu. Downgrading. Changing settings. But nothing seems to work. I've only been using Ubuntu base for about 2 months now. Prior I've always used Budgie, Pop OS and even bazzite (also technically ubuntu studio). But these problems seem to only occur on ubuntu base.

To note, major reason I wanted to use ubuntu base was for the sake of Visual studio code working somewhat flawlessly on here. Which it does.

Also I should note that I have run this specific laptop on Bazzite and PopOS. My other dual boot is bazzite.

I'm really new to command line, and I'm trying to move a folder full of FASTQ files into my directory. I haven't had any luck in the terminal, so I tried moving files using GUIs (nautilus and thunar). However, I can't move any files and I've been receiving these errors:

(thunar:865): GLib-GIO-CRITICAL **: 15:17:18.061: GFileInfo created without standard::size

(thunar:865): GLib-GIO-CRITICAL **: 15:17:18.061: file ../../../gio/gfileinfo.c: line 1845 (g_file_info_get_size): should not be reached

Any ideas on how to fix this or if I'm missing something?

I have a HP OfficeJet Pro 8500 that HP stopped supporting in Mac OS and Windows.

The printer works fabulously from Ubuntu with the HP supported driver.

I have been PDF'ing files and sharing to the Ubuntu device which has an automation to print any new files in a folder.

Can I do this better? I.e. have a driver that will print from latest Windows and MacOS rather than the faff of PDFing first?

I'd like my wife to just be able to hit file, print and be able to choose colour/bw and quality as with any other printer.

I was hoping to convert my much-customised OS to UEFI boot by updating to 26.04, putting a minimal 26.04 UEFI install with the same user details onto a new NVMe drive and using rsync -av to transfer the home, etc, and opt folders to the new install. After transferring the home folder things looked promising, but transferring /etc stopped any booting. Is there a way to make this work? Boot-Repair couldn't fix it.

I’m trying to diagnose a persistent read-only filesystem problem on an HP desktop and would appreciate ideas on what to test next.

System details:

• SO: Dual boot with ubuntu 18.04 and windows 10 on a HDD
• Machine: HP ENVY 750-500 Desktop PC series
• Motherboard: HP board ID 2B36
• BIOS version: 80.11
• BIOS date: 2015-04-01
• SATA controller: Intel 9 Series Chipset Family SATA Controller [AHCI Mode]
• Kernel driver: ahci
• Storage setup: SATA SSD connected internally

The SSD I tested is:

• Model: Crucial CT500BX500SSD1
• Firmware: M6CR072
• Capacity: 500 GB
• Interface: SATA III 6.0 Gb/s

Problem

After installing Ubuntu 24.04 on the SSD, the system would intermittently remount the root filesystem as read-only. The symptoms included:

• sudo touch /tmp/testfile failing with Read-only file system
• sudo apt update failing because it could not write to /tmp, /var/cache/apt, or /var/crash
• The system sometimes booting, but later behaving as if the root filesystem had become read-only

What I tested I tested the SSD and several different SATA cables:

• one brand-new SATA data cable
• two other data cables already in use with HDDs
• different SATA power cables
• disconnecting a HDD and reusing its SATA cables

Filesystem checks From a live USB, I ran:

sudo fsck -f -n /dev/sdc2

The result showed no filesystem errors. The output completed all passes without reporting problems.

SMART checks I installed smartmontools and ran:

sudo smartctl -a /dev/sdc
sudo smartctl -x /dev/sdc
sudo smartctl -t long /dev/sdc

Important results:

• SMART overall-health: PASSED
• Extended self-test previously completed without error
• No reallocated sectors
• No pending sectors
• No offline uncorrectable sectors
• But UDMA_CRC_Error_Count is 731

The full SMART output suggests the SSD itself is not failing in a classic way, but the CRC error count makes me suspect SATA link or motherboard-side issues.

Other observations

• The SSD benchmarks looked normal for a SATA SSD.
• The system is running in AHCI mode.
• I don’t fully believe all SATA cables and ports on the board are bad, so I’m wondering whether this could be a motherboard, BIOS, power, or controller issue instead.

My main question Given that:

• two different SSDs showed similar read-only behavior,
• multiple SATA data cables and power cables were tested,
• fsck found no filesystem corruption,
• SMART passed but UDMA_CRC_Error_Count is high,

what would be the next best step to isolate whether the problem is:

• the motherboard SATA ports,
• the PSU / SATA power,
• BIOS/firmware,
• or something else?

Would updating the HP BIOS be worth trying on this system?

Thanks in advance.

While trying to make a modification to a KDE4 subpackage for one of my retro-machines, I managed to break a good number of the other subpackages. My hunch would be that this has to do with using a newer compiler (gcc-9 from one of Ubuntu's own PPAs instead of gcc-5 that I used for the previous build from 10 years ago).

I'm now waiting for another build to finish that uses gcc-5 again, but it seems that this is a newer gcc5 than the one back then.

The old packages are still on the server, but are marked superseded. Fortunately I downloaded them because I feared I might have to roll back (as I can no longer properly do a local build).

Is there a way to bring those superseded packages back online? I had hoped that would happen automatically if I deleted the old version, but apparently not ... and I can't even fetch them with apt-get download foo=4:4.11<blabla>.

Thanks!

The last update of the Nvidia drivers failed and I had the message to send the failure report to Ubuntu 24.04. Since then, the display remains dark after the boot selection screen. I am unable to login.

I have two questions:

1. Is there a way to disable the GPU and use native graphics before the boot sequence?

2. What can be done to correct the driver issue?

I am behind a Fortinet SSL-inspecting network and need to trust the Fortinet root CA.

What works:

• Certificate exists in /usr/local/share/ca-certificates/Fortinet_CA_SSL.crt

• Certificate is valid PEM

• CA:TRUE

• update-ca-certificates --fresh succeeds and shows:

Replacing debian:Fortinet_CA_SSL.pem

• Symlink exists:

/etc/ssl/certs/Fortinet_CA_SSL.pem
47d00205.0 -> Fortinet_CA_SSL.pem

• OpenSSL trusts it:

openssl verify \
-CAfile /etc/ssl/certs/ca-certificates.crt \
/usr/local/share/ca-certificates/Fortinet_CA_SSL.crt

OK

• trust list works normally and shows system roots.

Problem:

• Almost all applications fail TLS/HTTPS as if the Fortinet CA is not trusted.

• Chrome only works in profiles where I manually imported the certificate.

• System-wide trust does not propagate to applications.

Things already checked:

• p11-kit-trust.so exists and trust module loads.

• trust list shows normal root certificates.

• Cert permissions are correct (0644 root:root).

• Cert contains exactly one PEM certificate.

• Reinstalled p11-kit, p11-kit-modules, and ca-certificates.

Environment:

• Ubuntu 26.04

• Fortinet appliance SSL inspection certificate

• Certificate subject:

CN=FG200FT925904109
OU=Certificate Authority
O=Fortinet

Question:
What trust path are desktop apps/Electron/Chrome actually using on Ubuntu 26.04, and why would the OS trust store (ca-certificates) verify the cert while apps still reject HTTPS unless manually imported?

EDIT: Ubuntu 26.04 system trust store correctly trusts my Fortinet SSL inspection CA, but desktop apps still fail TLS.

Evidence:

The Fortinet CA is installed in:

/usr/local/share/ca-certificates/Fortinet_CA_SSL.crt

update-ca-certificates --fresh imports it:

Replacing debian:Fortinet_CA_SSL.pem

System verification succeeds:

curl -Iv https://google.com

shows:

issuer: C=US; ST=California; O=Fortinet; CN=FG200FT925904109
SSL certificate verified via OpenSSL.

openssl s_client also verifies successfully:

Verify return code: 0 (ok)

So OpenSSL + /etc/ssl/certs/ca-certificates.crt trust path is working.

However:

• Most desktop apps fail HTTPS/TLS
• Chrome only works in profiles where I manually imported the Fortinet certificate
• Electron-based apps fail
• Appears apps are not consuming the system CA store

Question: On Ubuntu 26.04, what trust backend are desktop apps/Electron/Chrome/Snap/Flatpak actually using, and how do I force them to use the system OpenSSL trust store for a Fortinet SSL-inspecting network?

I am developing a Qt app, and considering whether to use PySide6 and PyQt6.

Is there any difference between them in terms of:

• performance?

• resource consumption (RAM/internal storage)?

• compatibility with native look and feel in GNOME?

I installed Ubuntu 26.04 LTS Desktop on my Galaxy Book2 Pro 5G. It only has one SSD, and I created a shared partition named "shared" (D:). When using Strawberry Music Player, I always get an error message; I need to access the shared partition before I can play music files. So I was wondering if automatically mounting the shared partition would solve the problem. I occasionally mount it to /home/ku/shared, but Strawberry Music Player can't see the music files in the shared partition. I think I might be doing something wrong. I've attached some screenshots; I hope someone can help me. Thank you!

This seems wrong.

is it normal for practically all the window navigation shortcuts to be broken because the dock shortcuts take precedence and launch applications from the dock?

For example, right now I’m trying to move Firefox to workspace number 4, but the Dock opens the application in slot number 4 even though I used different keybindings (Ctrl+Super+4) to move the windows to the workspace 4, whereas for the Dock it should only be (Super+4).

This is an extension of this question and of this answer. I asked some clarification there in the comments, but I received no answer.

I have a number of mp4 files, and their metadata title displays some undesirable text. I would be perfectly satisfied to replace that text with the file name, but without the file path and without the file extension.

If I use ... -metadata title="{}" ..., the title contains both the file path and the file extension.

If I use ... -metadata title="${basename}" ..., the title still contains the file extension.

So how should I modify the command to remove the file extension too?

As the link https://packages.ubuntu.com/search?keywords=boomaga&searchon=names&suite=all&section=all suggests, the Boomaga software is no longer available in Ubuntu 26.04.

I know that I can add the appropriate PPA and still use the old version (taking any risks).

However, my question is this:

What is the best way to easily preview printouts, rearrange pages, combine printouts, make booklets, or print multiple pages on a single sheet (all in one software) in Ubuntu 26.04?

I use fvwm, with sloppyfocus and autoraise (so that when a window receives focus, it automatically raises above overlapping windows). Since I upgraded to ubuntu 24.04.4, auto raise isn't functioning.

============================== Edited ===========================

Problem solved: I installed fvwm3 and used that instead of fvwm2, and all is now well. fvwm3 is working happily without my having to change my config file (which is in ~/.fvwm/fvwm2rc). I found the deb for fvwm3 at ubuntuupdates.org/pm/fvwm3 after I was unable to find it in the ubuntu repository (I've seen the claim that it exists in the universe repository, but apt said it wasn't available).

My current system configuration is as follows:

• CPU: AMD Ryzen 9 9950X3D
• Motherboard: MSI MAG X870E
• RAM: DDR5-6000
• PSU: PX-2200

I am currently experiencing issues on Ubuntu 24.04 where installing the NVIDIA graphics driver leads to an infinite boot logo loop and a black screen.

While investigating the issue, I came across reports suggesting possible compatibility problems between the RTX PRO 6000 Blackwell and certain MSI motherboards.

I would appreciate it if anyone who is successfully using the RTX PRO 6000 in an Ubuntu development environment could share their motherboard model and a stable hardware configuration.

In particular, I would also like to know whether this GPU has known issues with specific chipsets (e.g., X870E), or whether the problem is more likely related to BIOS settings or driver configuration.

I cannot start up my virtual box machines (which utilize ubuntu 24.04 server), as the startup is immediately aborted by the following error:

Error Log for Virtual Box 7.2.2 Debian Installed Snap:
VM Name: bob

Driver name clash. Another driver with the same name as the one being registered exists. (VERR_PDM_DRIVER_NAME_CLASH).

IConsole {6ac83d89-6ee7-4e33-8ae6-b257b2e81be8}

Since this had worked 2 days previously and I had not modified virtualbox, I'm assuming this is a ubuntu update issue.

I just installed Ubuntu 24.04.2 LTS (first time using Ubuntu) on my Lenovo Yoga Pro 7 Gen 10. Everything is working fine so far, but I can only get 2 of the 4 speakers to work on my laptop, and while I can turn Bluetooth on and off, it doesn't detect my wireless mouse. When I google the issue, I only find people with the same problem on the Gen 9, and their problem was solved by waiting for a newer kernel. Is this the only option? I would appreciate any help.

Till Ubuntu 22.04 I could just replace the /usr/share/sounds/freedesktop/stereo/alarm-clock-elapsed.ogg with a new sound file (with the same name) and it worked.
But in Ubuntu 24.04 it does not work. The same beeping sound reappears although I even deleted the file (/usr/share/sounds/freedesktop/stereo/alarm-clock-elapsed.oga – oga instead of ogg in the past).

Is there a new place and folder?

I searched the internet and dconf-editor but could not find any hint for a new location or solution.

I have the same error as described here... Couldn't Create Moklist: Volume Full - grub doesn't start at all

Disabling secure boot did not help.

I cannot boot into my OS and also with a liveUSB I cannot boot.

Laptop is an old ASUS. The OS on my HDD is Ubuntu and that is the only want I want.

I also read here... https://www.reddit.com/r/Fedora/comments/172azxc/live_usb_wont_boot_volume_full/ - that the only solution is to delete all the keys, reinstall them, save, and restart. I am just not sure how to do it. MY QUESTION: What I do first, second, third, etc.? It seems not recommended to do this (= risky), but I have no choice, so I want to do it right. Do I delete all keys at once and then what as to how to reinstall? Or do I just do the Platform Key (PK) and then either "set new key" or first "delete key" and then what? Or another or all listed secure boot variables?

Here some screenshots:

I noticed that my script is probably running in a wrong time (UTC maybe?). But I've added CRON_TZ into the crontab.

EDIT

It's Ubuntu 18.04, DigitalOcean.com droplet which was created from snapshot.

I've checked syntax and it is correct I think. Do you know where could be the problem?

CRON_TZ='Europe/Prague'
53 12 * * * touch /home/futilestudio/feedproject/cronsupervisor/scripts/touch0.txt

The script should be executed 12:53 Slovakia/Czech Republic time (in 24 hour format) but it wasn't - it haven't created a touch0.txt. If I execute it manually it works.

CONFIRMED

I tried to put there a command in UTC and it created a file (SK/CZ is 13:24 but UTC is 11:24 right now)

24 11 * * * touch /home/futilestudio/feedproject/cronsupervisor/scripts/touch0.txt

EDIT

It's 14:20 Prague time and I've set two jobs:

21 12 * * * TZ=Europe/Prague touch /home/futilestudio/feedproject/cronsupervisor/scripts/touch0.txt
21 14 * * * TZ=Europe/Prague touch /home/futilestudio/feedproject/cronsupervisor/scripts/touch1.txt

and removed touch0.txt from the directory.

14:21 - created /home/futilestudio/feedproject/cronsupervisor/scripts/touch0.txt

How to disable these advertisements, without disabling the update and login parts (the Want to make a highly secure kiosk, smart display or touchscreen? ... part)?

This is the same issue as here: Getting openconnect vpn to work through gui , but my additions to it were deleted and I was asked to create a new question.

In fact, there are a number of folks asking similar questions here, all with 0 responses.

Software versions: Ubuntu 14.04, openconnect 5.02

Main issue: I'm trying to add a VPN connection into network-manager, using openconnect. when i supply my VPN username and password, it connects successfully, but i can't resolve DNS.

If I run openconnect in the terminal via sudo, DNS works.

sudo openconnect -u <username> https://<vpn concentrator name>

More details:

1a. When connecting via openconnect and network-manager even though I've explicitly added DNS and a search domain under the ipv4 tab, only the search domain ends up in /etc/resolv.conf. Even if I don't supply DNS and search domains, I can see in the logs that it's getting that information from the VPN concentrator. Again, the search domain is updated properly. [log below]

1b. When connecting via sudo in a terminal, resolv.conf is populated properly with DNS and search domains even though I haven't added that information in the command line or provided a path to a vpnc-script. It must be getting it from the VPN concentrator. [log also below]

2a. When connecting via openconnect and network-manager, a new interface 'vpn0' is created.

2b. When connecting via sudo and command line, a new interface 'tun0' is created.

Log when connecting via network-manager:

Despite all the noise in the log about updating resolv.conf it removes the nameservers but doesn't replace them with the IP addresses in the log. It does update the search domain correctly, so it's likely not a permissions issue.

Log when connecting using sudo openconnect in a terminal:

NetworkManager[784]:    SCPlugin-Ifupdown: devices added (path: /sys/devices/virtual/net/tun0, iface: tun0)
NetworkManager[784]:    SCPlugin-Ifupdown: device added (path: /sys/devices/virtual/net/tun0, iface: tun0): no ifupdown configuration found.

dbus[471]: [system] Successfully activated service 'org.freedesktop.hostname1'

Nothing about updating resolv.conf, and yet it properly updates the name servers and the search domain.

Update If I ignore all the warnings in resolv.conf and add the vpn concentrator nameservers to it, I'm instantly able to browse. Of course as soon as I disconnect, those changes are overwritten.

there was a bug on this, back in 2012, but it expired. The issue seems to be the vpnc script.

I tried manually updating my vpnc-scripts to the latest versions, but to no avail.

Some further research turns up that as of 12.04 resolv.conf is no longer where nameservers go for dns resolution when using network-manager. That's why it works when I use the command line, but not when using network-manager. Rather the nameserver 127.0.1.1 [dnsmasq] is added and that nameserver is told the IP addresses of the actual nameservers.

The big advantage is that if you connect to a VPN, instead of having all your DNS traffic be routed through the VPN like in the past, you’ll instead only send DNS queries related to the subnet and domains announced by that VPN.

Update Disabling dnsmasq as explained in link above solves the issue because /etc/resolv.conf is populated.

This is not a real solution though, it's a fallback.

I follow this issue to configure PIdgin for MS Lync 2013 .

I get this message :

Web ticket request to https://rproxy.mycompany.com:443/CertProv/CertProvisioningService.svc failed

Known that settings has been configured as following:

And No proxy:

i received this certificate from MS sysadmin .

And i don't know if it is useful in Ubuntu . If so , How can i import it?

And Why rproxy appeared in message error even there is no proxy in my settings .

I mean :

https://rproxy.mycompany.com:443/CertProv/CertProvisioningService.svc

UPDATE :

I found where can i import certificate :

However , i get new error message:

SSL Connection Failed

Known that Authentication Scheme is: Kerberos , not TLS-DSK
