I'm running Pop_os 22.04. I recently tried to install openrgb, which required me to add the thopiekar/openrgb repository. immediately after adding this repository, I started getting the following errors every time I tried to upgrade or install something (including openrgb)

ERROR (dkms apport): kernel package linux-headers-6.17.9-76061709-generic is not supported

I searched the error codes online and tried the following fixes as well, none of which fixed the issue:

1990  sudo apt install linux-headers-generic

1991  sudo apt upgrade -y

1992  sudo dpkg --configure -a

1993  sudo add-apt-repository --remove ppa:thopiekar/openrgb

1994  sudo apt update

1995  sudo apt update && sudo apt upgrade -y

1996  sudo dpkg --configure -a

1997  sudo apt install --fix-broken

2005  sudo apt purge openrgb

I've installed openrgb on arch with no problems in the past. Any thoughts? Thanks

I have a laptop with an onboard Radeon 680M and a RTX 4050; checking nvidia-settings, it does not show the option to switch between the gcards, while calling prime-select query the following options are shown: nvidia|intel|on-demand|query (I don't have a intel)

Is the Radeon not supported or I should try a different approach?

I'm using Kubuntu 26.04 with kernel 7.0.0-15-generic. After suspending the system with Meta+L and leaving the computer for a while, I encounter this screen.

I'm forced to perform a hard reboot via the power button or use the REISUB to restart. Has anyone experienced this, or knows a solution?

I am planning to migrate my main Workstation from Windows to Ubuntu 24.04 LTS (GNOME 46). Since i want to stay on Wayland for my daily driver. I want to ensure a 1:1 input feel for a mix of competitive games without having to switch back to X11.

Hardware:

• NVIDIA RTX 5060.
• Intel Core i5-13400F.
• Wayland (GNOME 46) with 125% Fractional Scaling.

Upgrading from 25 to 26.04, upgrade hangs on "setting up wvdial". Now i can't boot into my previous install, the startup process results in a kernel panic. I can restart the update process from recovery mode, but it still hangs in the same place. How do i get either my old setup back or the upgrade completed without wvdial?

Edit: rebooted into linux 6 recovery mode, dropped down to root shell and did

sudo apt remove wvdial

Which removed it, and then apt just automagically went on to finishing the upgrade

My system wont upgrade because it says I have a unofficial version of libopenexr 3 1 30. How can I reinstall the official version? I have not tried anything at point because i don't know where to start.

I have a number of hosts running Ubuntu in a lab managed by ansible. Ansible is used to upgrade and install specific deb and apt packages.

I've just upgraded one to 26.04 LTS. The upgrade caused a problem with ansible, triggered by the transition to sudo-rs.

How can I specify for a specific machine a different sudo executable; in this case, /usr/bin/sudo.ws?

I am using Ubuntu 24.04 LTS on a ThinkPad E15 Gen 5 with an Intel i3 13th Gen processor.

I always keep the system in “Power Saver” mode. However, sometimes after booting the laptop, I notice that the power profile has automatically changed to “Balanced” mode without me changing anything manually.

Is this expected behavior in Ubuntu 24.04, or could this be a bug?

Has anyone else experienced this issue, and is there a way to force the system to always stay in Power Saver mode across reboots?

I applied updates yesterday to prepare for my upgrade to Ubuntu 26.04 today. However, when I came back this morning, before the upgrade, I found my fans running at max speed as soon as Ubuntu booted. My CPU and GPU are both idling and at ~50°C and ~35°C, respectively. So there's no need for my fans to be working overtime. Looking in KDE's System Monitor, I see it's correctly reporting my fans to be spinning at 4000-5000 RPM.

I've had this issue before on CachyOS, so it seems this might be a Kernel issue. My updates yesterday evening included a Kernel patch, which would explain why I wasn't running into this issue earlier. I proceeded with my upgrade to Ubuntu 26.04, hoping the issue would resolve itself, but the fans are still spinning at max speed.

I have a dual-boot setup with Windows 11. Booting into Win11, my fans idle at expected levels, rather than screaming at 100%. Putting a load on the system correctly turns the fans up. This rules out the UEFI as a problem.

I've been using Linux for years, but I'm still a complete noob when it comes to Kernel-level issues. How do I go about debugging this?

I have installed Ubuntu on an external SSD. I did a full instalment on it and it works fine on the computer where I installed Ubuntu on. But I would like to be able to use that same SSD and plug it in an other computer, and use Ubuntu on that computer as well.

When I put the SSD in my second computer, and choose the SSD as boot drive, the computer starts, I see the logo of the computer but then it goes black and then Windows starts (because the internal drive with windows was still first in the boot order).

I have already turned off secure boot and fast boot on the second computer. I have also tried putting the SSD first in the boot order but that also does not work.

The two computer I am using are:
First computer: Lenovo Thinkpad
Second computer: PH Probook

On Ubuntu Studio 25.10 and 26.04 my Audient iD4 MkII sound interface stops working when resuming from standby. This is what I see in dmesg:

uac_clock_source_is_valid(): cannot get clock validity for id 41
usb 2-1: clock source 41 is not valid, cannot use
usb 2-1: 2:1: cannot get freq (v2/v3): err -71
usb 2-1: 2:1: cannot set freq 48000 (v2/v3): err -71

On Windows 11 it works ok even after resuming. Tried different USB ports but no success. Any ideas? Disconnecting and connecting the interface solves the problem though.

I am trying to install a program that requires java/jvm in Ubuntu 26.04:

$ sudo ./cplex_studio2212.linux_x86_64.bin

This works under Ubuntu 24.04 but fails in 26.04 with the following error. Hence the question on how to fix it.

Environment

• OS: Ubuntu 26.04 LTS (fresh install, last LTS)
• Hardware: AMD-powered laptop [Lenovo IdeaPad-Slim-5-15ARP1]
• Session: Wayland
• Firefox: installed from Mozilla APT repository (removed snap first)
• Thunderbird: installed from Mozilla APT repository (works, but shows warning)

What I did

1. Installed Ubuntu 24.04 LTS on a new laptop
2. Removed the preinstalled Firefox and Thunderbird snaps
3. Followed the official Mozilla instructions to add the Mozilla APT repository and install the .deb builds
4. Thunderbird launches normally
5. Firefox fails to start

Expected behavior

Both Firefox and Thunderbird should start normally from the APT packages, as on previous Ubuntu releases.

Actual behavior

• Firefox: crashes instantly and sometimes shows the Mozilla Crash Reporter instead of a browser window
• Thunderbird: starts, but prints a sandbox warning in terminal

Terminal output

Firefox:

[16570] Sandbox: CanCreateUserNamespace() unshare(CLONE_NEWPID): EPERM
[16567] Wayland Proxy [0x7bc5c6587010] Error: StartProxyServer(): bind() error : Permission non accordée

: 'glib warning', file toolkit/xre/nsSigHandlers.cpp:201

Followed by multiple additional warning paragraphs.

Thunderbird:

Sandbox: CanCreateUserNamespace() unshare(CLONE_NEWPID): EPERM

What I've already checked

• Both applications were installed using the exact steps from the official Mozilla website for Ubuntu
• Thunderbird works despite the sandbox warning, Firefox does not
• Errors mention AppArmor (label="firefox (enforce)"), Wayland proxy bind permission, and unshare(CLONE_NEWPID): EPERM

Question

How do I fix the Firefox startup crash on Ubuntu 24.04 after replacing the snap with the Mozilla APT build? Is this caused by the new AppArmor user namespace restrictions, the Wayland sandbox, or a missing permission, and what is the correct way to allow Firefox to create its sandbox without reverting to the snap?

I am unable to run Ubuntu properly with my NVIDIA RTX 5050 GPU. Both Ubuntu 24.04 and Ubuntu 26.04 result in a black screen when the NVIDIA driver is enabled. The system only works using nomodeset, but then GPU acceleration is unavailable and resolution is limited (around 720p).

I can only install and boot the system using GRUB modification (nomodeset), but enabling NVIDIA drivers causes a black screen after boot.

I have tested multiple NVIDIA driver versions (570, 580, 595), but all result in the same issue.

System information

• GPU: NVIDIA RTX 5050

• CPU: AMD Ryzen 5 5500

• RAM: 8GB DDR4 3200MHz

• Storage: 256GB NVMe SSD

• Motherboard: Gigabyte B550M-K

Steps already tried

1. Boot with nomodeset (only working method)

At GRUB:

• Press e

• Add:

nomodeset

Then boot with Ctrl + X

2. Install NVIDIA drivers

sudo apt update
sudo apt install nvidia-driver-580

Also tested:

sudo apt install nvidia-driver-570
sudo apt install nvidia-driver-595

3. Remove broken NVIDIA installation (via chroot / recovery)

sudo apt purge '^nvidia'
sudo apt autoremove --purge
sudo rm -f /etc/X11/xorg.conf
sudo rm -f /etc/modprobe.d/nvidia*
sudo update-initramfs -u
sudo update-grub

4. Update kernel / system packages

sudo apt update
sudo apt upgrade
sudo apt install linux-generic-hwe-24.04

Current result

• System boots only with nomodeset

• Without nomodeset, black screen occurs immediately after GRUB

Looking for a stable solution to run RTX 5050 properly on Ubuntu (kernel/driver configuration fix or compatibility workaround).

I did apt-get install jmeter but can't get it to run.

First, it seems to use JAVA_HOME, which is a Really Bad Idea since it can be anything in the range of 8 to 26. But even then I can't find a JVM version with which I can run it. If I use JAVA_HOME pointing to Java 11, jmeter GUI starts, but right clicking load produces the following error in the log:

2026/05/15 12:47:34 WARN  - jmeter.gui.util.MenuFactory: Could not instantiate org.apache.jmeter.visualizers.RespTimeGraphVisualizer java.lang.UnsupportedClassVersionError: org/jCharts/properties/PointChartProperties has been compiled by a more recent version of the Java Runtime (class file version 65.0), this version of the Java Runtime only recognizes class file versions up to 52.0
        at java.lang.ClassLoader.defineClass1(Native Method)
        at java.lang.ClassLoader.defineClass(ClassLoader.java:756)

It is apparent that some of its classes need at least Java 21. However, when I try to run jmeter with Java 21, I get:

An error occurred: Unable to make field private static java.lang.String sun.awt.X11.XToolkit.awtAppClassName accessible: module java.desktop does not "opens sun.awt.X11" to unnamed module @42f30e0a

And the GUI will not start. Apparently, base JMeter is not built to modern Java standards and will fail to start with Java 21.

How do I get JMeter in Ubuntu 25.10 to run with usable GUI?

Issue Title: System hard freezes and black screen preceded by amdgpu DMCUB diagnostic errors on Ryzen/Radeon platform.

Description: I am experiencing intermittent hard system freezes on my laptop, particularly when using the Performance power profile. The failure follows a consistent pattern:

1. Immediate Display Loss: The screen goes black instantly.

2. Unresponsive Input: The keyboard and mouse become completely unresponsive (caps lock light does not toggle).

3. Thermal/Fan Behavior: Even though the system is frozen, the fans immediately ramp up to 100% (Full RPM) and stay there until a hard manual reboot is performed.

4. Error Logs: The system logs capture the following error shortly before or during the crash: amdgpu 0000:05:00.0: [drm] *ERROR* dc_dmub_srv_log_diagnostic_data: DMCUB error - collecting diagnostic data

System Context:

• Platform: AMD Ryzen with integrated/dedicated Radeon graphics.

• Operating System: Ubuntu (26.04/Linux Kernel 7.0.0-15-generic).

• Power State: The issue is most prevalent in "Performance" mode, suggesting a possible conflict with PCIe ASPM (Active State Power Management) or Voltage/Frequency scaling transitions.

Suspected Cause: The error points to a crash of the DMCUB (Display Core Microcontroller). When this microcontroller fails, it seems to lose synchronization with the system's thermal management, causing the fans to default to a "fail-safe" maximum speed while the display engine dies.

I was trying to use these commands to install Firebird on Windows Subsystem for Linux (I'm new to this).

wget -O firebird.tar.gz https://github.com/FirebirdSQL/firebird/releases/download/R2_5_9/FirebirdSS-2.5.9.27139-0.amd64.tar.gz

then:

tar -zxvf firebird.tar.gz

then:

sudo ./install.sh

And I typed my password. All I got was: sudo: './install.sh': command not found

What am I doing wrong? I used this instruction (It's a Polish website, but you can translate it.): https://dgcs.pl/firebird3-0-linux/

Hey guys I've been encountering plenty of problems in Kubuntu 26.04 that wont let me use my pc normally:

1. Translucently and wobble window effects get reapplied after each reboot without my consent

2. Chrome on xorg with using the built in classic option from appearance aka colors, the title bar buttons disappear when I try to type on the address bar.

3. Plymouth animation appears during transition from sddm to desktop (I have selected None as a transition)

4. The locale on the time widget in taskbar rejects any effort to be changed and still uses the Greek time format ΠΜ, ΜΜ, When I clearly set it to American am pm. I use Greek only for the keyboard

I have to note that I also use klassy I seriously need to find a solution because the name implies LTS and I am disappointed.

Can anyone help me? Plasma 6.6.4 Just upgraded

Why would some USB drives be slower than other and is there anything that can be done about it?

Now that I am upgrading to XUbuntu26.04, I've been running some daily backups on both systems.

The time to complete the backup ranges from about 80 minutes to something close to 150 minutes. Thus far I am not finding much if any difference in timing between 24.04 and 26.04, although two years ago I did find 22.04 significantly faster on USB2 type drives. The drives I am using are USB 3.2, purchased some months back as a 10 pack so, they are probably from the same production run.

What I am noticing is that some specific drives run around 90 minutes on 24.04 and 26.04 while other drives take close to 140 minutes on 24.04 and 26.04. I am using very similar ports in both cases. The systems are identical Optiplex systems. The port is appropriate for USB 3 devices (labeld SS).

I have done some further testing then looked at the values reported by lsusb -tv Three of them reported an ID of 13FE and what I think is the manufacture (Phison Electronics). One of the drives reports asn ID of 325d. Two of them are requiring about 140 minutes, the other two required about 100 minutes. There were all purchased as Teamgroup 64GB 3.2 USB drives. The one which reports a blank manufacturer is one of the two fast drives.

I have bought a printer, an HP Envy 6500e. Although the driver is available, my notebook with Ubuntu 24.04 installed is not able to install it. It shows the printer as available, but it fails to install.
I tried with the standard Ubuntu installation procedure and using the hp-setup command.
I have also updated hp-plugin and I tried to connect the notebook to the printer through the USB cable or by Wi-Fi indicating the IP address manually.

I tried the printer using a Windows PC and Android smartphone and it works.

In all cases the printer installation failed. Any ideas?

This week my OS updated a few packages and after the update my nvidia drivers stopped working. I was using nvidia-driver-580-open and tried switching to nvidia-driver-590. The computer still felt laggy so I tried switching back to the 580 drivers but I ran into the following issue

    Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 linux-modules-nvidia-580-open-generic-hwe-24.04 : Depends: linux-modules-nvidia-580-open-6.17.0-23-generic (= 6.17.0-23.23~24.04.1+1) but it is not going to be installed
                                                   Depends: nvidia-kernel-common-580 (>= 580.142) but 580.126.09-0ubuntu0.24.04.2 is to be installed
E: Unable to correct problems, you have held broken packages.

I also tried using

ubuntu-drivers autoinstall

as well as purging, updating and re-installing the drivers.

I am using Ubuntu 24.04 LTS and have a 3060 RTX Mobile

Currently I've tried the 570 and they showed the same issue as the 590, laggy, without smooth transitions in the desktop and couldn't run games. And I've also tried the 535 drivers that led me to have to log in with tty4 to purge them.

When I try to manually install the packages manually

sudo aptitude -f install nvidia-kernel-common-580 
The following NEW packages will be installed:
  nvidia-firmware-580-580.126.09{a} nvidia-kernel-common-580 

I tried looking online and I couldn't find nvidia-kernel-common-580.142 available anywhere

After trying many solutions from Unable to correct problems, you have held broken packages, none of them worked as when I perform the install I do not have any nvidia related packages on my computer.

Currently the only drivers that somehow work are the Xorg drivers and that's what I'm trying to switch from into nvidia drivers.

It seems to me like the packages are still not available but I cannot confirm the issue is on my side

Also my sources list reads as

Types: deb deb-src URIs: http://pt.archive.ubuntu.com/ubuntu/ Suites: noble noble-updates noble-backports Components: main restricted universe multiverse Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg  Types: deb deb-src URIs: http://security.ubuntu.com/ubuntu/ Suites: noble-security Components: main restricted universe multiverse Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg 

I've now tried downgrading the kernel from version 6.17.0-23-generic to 6.17.0-22-generic, running into the same issues as before.

I also tried

sudo apt install ca-certificate
sudo rm -rf /var/lib/apt/lists/*
sudo apt update
sudo apt upgrade
sudo ubuntu-drivers autoinstall

And still got the same error as before

Potential temporary fix

So I tried purging and installing the packages once more, but then had trouble returning to not having drivers

I disabled secure boot and after a restart the X.org drivers in the Additional Drivers menu were selected.

To try and properly install them I pressed another random driver, then X.org drivers and selected "apply selected".

I rebooted the computer and after the reboot the 590 proprieetary drivers of nvidia were installed and working correctly.

Still did not fix the issue with the 580 drivers but at least this works.

I'm from India, currently running Ubuntu 24.04.4 LTS. I am excited to upgrade to the newly released 26.04 LTS. However, even today's morning (Apr 25), my software updater couldn't find a newer version to upgrade to. Articles like (https://linuxconfig.org/upgrade-ubuntu-24-04-to-26-04) and (https://linuxize.com/post/how-to-upgrade-to-ubuntu-26-04/) suggest a manual upgrade via the terminal, first upgrading to a non-LTS version (25.10). I am not willing to wait till 26.04.1 LTS release.

How do I upgrade? Please help!

I am trying to install conjure-up to install the kubernetes on my ubuntu (16.04.1) with the command:

sudo snap install conjure-up --classic

After a few seconds, the below error is shown:

I recently bought a Wireless USB Adapter TP-LINK TL-WN722N v3 (https://wikidevi.com/wiki/TP-LINK_TL-WN722N). At first, it seems to work but I've noticed that there were, in fact, some problems with drivers after all. So I decided to install one, in following way:

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtlwifi-new-dkms

When that didn't work I followed this guide:

git clone git://github.com/lwfinger/rtl8188eu
cd rtl8188eu
make
sudo make install
sudo cp -v ~/RTL8188EU/rtl8188eu/rtl8188eufw.bin /lib/firmware/rtlwifi/
sudo depmod -a
sudo update-initramfs -u
sudo modprobe 8188eu

But it gave me 'modprobe 8188eu - Exec' format error on the last command. I've also tried using dkms, but that does not seem to work either.

sudo apt-get install git dkms
git clone https://github.com/lwfinger/rtl8188eu.git
sudo dkms add ./rtl8188eu
sudo dkms install 8188eu/1.0

I'm running: Linux version 4.4.0-116-generic (buildd@lgw01-amd64-021) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.9) ) #140-Ubuntu SMP

Right now the device is not recognised in any way after connecting it to USB port. How can I make it running?

This happens to me all the time. What I actually want to do is "Ctrl+A, Shift+|". But instead, I accidently hit "Ctrl+A, Shift+C". And it brings me to a new instance of screen.

But there are some output on my last screen which I would like to reference later. Wonder how to get back to it?

I'm trying to migrate to my new NVMe Samsung 950 pro.

chroot /mnt/boot-sav/nvme0n1p3 update-grub
grub-probe: error: cannot find a GRUB drive for /dev/sda1.  Check your device.map.

Process:

• Copied/pasted via Gparted (lastest gparted live-cd)
• Ran boot-repair (with 15.10 ubuntu desktop)
• failed on update-grub

http://paste.ubuntu.com/13244403/

Old drive had:

• sda1 fat32 EFI
• sda2 ntfs
• unallocated (had to shrink a small amount for new drive)
• sda3 ext4
• sda4 linux-swap

My first guess is that I'm no longer using an sd, but an nvm prefixed device.

Any thoughts/help is appreciated.

$ update-grub
grub-probe: error: cannot find a GRUB drive for /dev/sda1.  Check your device.map.

When I look in /boot/grub I do NOT have a device.map. I read that I don't need one for grub2, but I generated one, ran update-grub and ran into the same message as above.

I attempt to reboot anyway, and my EFI only shows a Windows Boot Manager as a bootable item, for which it lands on a windows recovery screen. The Ubuntu partition isn't listed as a bootable drive in EFI.

I have a RAID-5. I'm trying to replace a failing drive in Disk Utility GUI. I added a new drive as a spare, then did "Remove Component" for the failing drive. How do I tell it to actually use the spare (write all the parity data, etc)?

I tried re-adding, because I got nervous...

$ sudo mdadm /dev/md127 --re-add /dev/sdd

mdadm: --re-add for /dev/sdd to /dev/md127 is not possible

In a terminal window, I can use File > Open Tab to get two tabs in the same window.
Then, if I move the terminal up to the top of the OS, those two tabs become two separated windows.

How can I merge those two windows back to one (like I had before)?

Does anyone have any good ideas as to native MySQL GUI clients for Ubuntu?

So far I've tried MySQL Workbench, which never seemed to work properly, phpMyAdmin which I found a bit slow, and Navicat which is a windows port and runs under wine, but none of these is perfect. In an ideal world, I'm looking for something like a native version of navicat.
