I am still getting error messages and distorted screens with https://discourse.ubuntu.com/ and now and then "This site can’t be reached". What is the latest status here? Is the DDOS attack still going on?
I have an even older dedicated Linux machine with a GTX-560 on an old ASUS Maximus IV motherboard with an Intel i7-2700K, and after upgrading to 26.04 it still feeds two monitors just fine. (Might be a clue here?); (I am not a gamer, hence the continued use of the GPUs, they are fine for work.)
On my MSI 399 Pro Carbon, 24 thread AMD, with the 760, I have tried to use the 470 Nvidia driver to no avail, and I went back to the recommended Nouveau. Is there a legacy procedure of any kind or software mod to get two screens again on my best machine?
I am unsuccessful in establishing a RDP remote login connection to Ubuntu 26.04LTS.
I followed the instructions here. It is a fresh installation of Ubuntu.
As a client I use Remmina. Authentication works, but the screen remains black, with no error. Please see screenshot. The top border of the screen shows some "colors" when looking at it exactly.
In contrast, RDP Remote Desktop sharing works. Connection from other client devices equally do not work.
Remmina logs as follows:

Has anyone been successful installing Ubuntu on an Asus z170 Deluxe motherboard? I am new to this operating system, and so far have been unable to install the OS. I boot from a USB PNY 32GB, it boots, get the Ubuntu screen, allow the timer to run down, and then the computer freezes. I must reset the system to restart. Secure Boot is OFF.
I followed troubleshooting steps precisely, but I had no success. I tried every combination of BIOS settings and had failure after failure.
A few weeks ago, I wanted to try Ubuntu for my laptop that is also my main computer. Two days ago, I installed it on an external HDD I had bought for the occasion. My SSD (not external) was still on Windows, and I absolutely want to keep Windows in case I need it.
After using Ubuntu for a while, I realized that despite using USB 3.2, the HDD simply isn't fast enough to keep up with what I'm doing, so today I wanted to swap Windows and Linux from drives, but after spending hours trying to do so, it just won't work, I literally tried resetting Windows hoping it'll let me choose where to download it, but it didn't and after hours of waiting a download, it put itself back on my SSD and I can't put Ubuntu on it at the same time since Windows won't let me create a partition that's bigger than 50GB despite having my SSD 32% used. I thought that I'd try downloading Ubuntu again on the HDD (since I had formatted it earlier to try to put Windows on it) and then use Ubuntu to create a partition, but now that I've installed Ubuntu again and told it specifically to go on the SSD, it somehow managed to put itself on the HDD anyway.
I don't even know what to do anymore at this point. What should I do? I feel like absolutely nothing works correctly when I try to tinker around with OSs.
I had to rebuild my FLASH disk after a rebuild that used Ubuntu Server 24 first (because the DVD no longer contains the full Ubuntu Desktop configuration). Neither logout/login nor full reboot after the described removals works.
The previous successful answer was to rm -Rf ~/.cache/thumbnails/fail
from Ubuntu 24.04 File thumbnails not visible on desktop
That no longer works for me.
I sincerely hope the only workable answer now ISN'T starting from Ubuntu 22.04 and doing an online full system rebuild.
I recently noticed that my scene in a new Unity project was lagging/getting choppy even though it was just a tilemap with a handful (~10) game objects thrown in. Looking in the profiler I found that there was a thread called “Audio PulseAudio Mixer” that seemed to be causing large frame time spikes: from ~5ms to ~125ms. This seemed strange because there is no audio in the game. No audio listener, even. Nothing that I am aware of that could remotely require any activity in an audio thread. I even have "Disable Unity Audio" checked in Project Settings.
I’m on Ubuntu 24.04.4 as a recent Windows refugee, and my (limited) understanding is that ~~PulseAudio was standard before 24.04 when it was replaced with PipeWire.~~ PipeWire is a wrapper for PulseAudio:
pactl info | grep 'Server Name'
returns
Server Name: PulseAudio (on PipeWire 1.0.5)
I have no idea if that means anything.
I am aware that Unity is still a work-in-progress on Ubuntu, but I am very keen to not have to go back to Windows (or head over to Mac).
Many thanks for any help.
(This question is no longer cross-posted on GameDevSE)
Edit: I'm using a Focusrite Scarlett 2i2 (3rd Gen) audio interface, if that's at all relevant.
As the title says. I have Ubuntu 26.04 LTS and the Top Bar icon for Livepatch is missing. I did have to go to /etc/update-manager/release-upgrades to change the prompt to "Prompt=lts" so it can be on LTS (install put it on the standard release cycle for some reason). Livepatch is enabled and the icon is on as well, but none are present. Help me figure this out please.
Please inform us when the official patch for CVE-2026-31431 will be available
I have a script I use to allow me to plug in a second keyboard and change what keys are sent when pressed. I use it to send key combinations that execute macros in my audio editing software. It's become a vital part of my workflow. Here is the script:
#!/usr/bin/env python3
import os
from evdev import InputDevice, categorize, ecodes
#dev = InputDevice('/dev/input/event6') # Do not use event numbers for identifying keyboard as they change with reboots.
dev = InputDevice('/dev/input/by-id/usb-CHESEN_USB_Keyboard-event-kbd') # Use IDs for identifying keyboard as they do not change with reboots.
dev.grab()
for event in dev.read_loop():
if event.type == ecodes.EV_KEY:
key = categorize(event)
if key.keystate == key.key_down:
if key.keycode == 'KEY_ESC':
os.system("xte 'keydown Control_L' 'keydown KP_0' 'keyup KP_0' 'keyup Control_L'") # Fill TS with 50ms roomtone
elif key.keycode == 'KEY_F1':
os.system("xte 'keydown Control_L' 'keydown KP_1' 'keyup KP_1' 'keyup Control_L'") # Fill TS with 100ms roomtone
elif key.keycode == 'KEY_F2':
os.system("xte 'keydown Control_L' 'keydown KP_2' 'keyup KP_2' 'keyup Control_L'") # Fill TS with 150ms roomtone
How do I change this script to work with Wayland? As I understand it, it uses things like evdev and xte, not sure what else, which don't work in Wayland.
In looking into this, I've seen reference to an issue with the commands sending multiple keys rather than the lines of the script being for simple substitutions. I don't see anywhere how to deal with this in Wayland.
I'm not a coder by a long shot and no longer remember how this was put together.
So for some reason whenever I try to use bluetooth on my laptop only one window produces sound while the other only produce sound when said window is also making sound. I remember I had a similar issue with this in windows 11 and I'm not entirely sure why it's happening here. The sound page in settings acts like my device works and in pavucontrol when I switch my bluetooth device between SBC and SBC-XQ it work for like a second and then silence. I'm using a fully installed Kubuntu 26. Please help.(btw this happens in both pulseaudio and pipewire)
Just picked up a new Asus Zenbook S16 (UM5606GA) Ryzen AI 9 465
I have attempted to install ubuntu quite a few times along with a bunch of other linux flavors. They all have the same issue.
First off When installing ubuntu I have to use "nomodeset" at grub for the live installer and after install.
2nd and most important is I can not get the Laptop speakers to work, I have done various searches, tried a bunch of fixes, Tried to use AI to help me figure it out.
As far as I can tell, There is no "map" for this machine, and all I get is Dummy output. From what I have figured out it has something to do with the Cirrus Amplifier and Ubuntu/any other linux can not seem to activate the Amps and can not map the speakers. All I can get is HDMI out and Headphone out. I was wondering if anyone else has had this issue and may have advice other than waiting for it to get put into the kernel.
also, I have attempted mainline kernels as well. No Luck.
Specs:
Deduced my issue to a faulty Nvidia graphics card driver, so I'm currently stuck in emergency mode. I tried to replace it with a previously tested driver, but apt-get is somehow now failing.
Err: could not return resolve 'archive.ubuntu.com'.
If more info is needed, please let me know.
In the terminal how do I change the GFX driver Nvidia 580, installed in error, to the Nvidia 535 which is recommended for the Nvidia GeForce RTX 3060. Followed by cleaning up any drivers which have been used in the past?
I followed the instructions in another thread to fix something, but since it didn't work, I'd like to go back and restore the original configuration.
So, as the title says, how can I restore and go back after running these commands?
sudo chmod -R ugo+rX /lib/python3.12/
sudo chmod -R ugo+rX /lib/python3/dist-packages/
I can use a tethered connection but there is no option for a wifi connection when I use Ubuntu from a USB.
I saw Dirty Frag: Universal Linux LPE (CVE-2026-43284 and CVE-2026-43500), which yields a root shell (!) on 24.04.4.
In an (isolated) 26.04 x86-64 VM, I've reproduced it with both V4bel/dirtyfrag and 0xdeadbeefnetwork/Copy_Fail2-Electric_Boogaloo.
How should I patch my system to secure it from this vulnerability?
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:

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

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
Ive had a fairly smooth experience on Kubuntu, only switched from Windows some time around X-Mas so I'm fairly new to linux. But a bit ago i had to mess around a little with the NVIDIA drivers. Don't remember why or what i did exactly and nothing seems to work badly ATM. But every time i log into the OS now i get this message:
32-bit NVIDIA driver files were not found on your host system. It is recommended that you install them for the best experience. To install:
sudo dpkg --add-architecture i386
sudo apt update
sudo apt install libnvidia-gl-595:i386
Entering the first line makes me type in my password and then does nothing anyway.
3rd line gives me this:
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package libnvidia-gl-595:i386 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'libnvidia-gl-595:i386' has no installation candidate
I did go to the GitHub link that came with the message for more info, but it did not help. I also asked the AI to find me some solution to this, but it did not help. So the question is how do I get this installed? And if there for some reason is no way around this does it even matter? I don't want to ignore this and have it cause problems in the future because like I said things seem to work fine despite this message.
I have a computer running Ubuntu 24.04 LTS desktop where I have QEMU/KVM running. One of the guest OS is Windows 11. This VM has secure-boot on as required by Windows. The secure boot certificates originally issued in 2011 will expire next month. The new certificates were issued in 2023.
The above page shows a table of expiring certificates:
| **Expiring Certificate** | **Expiration date** | **New Certificate** | **Storing location** | **Purpose** |
| ----------------------------------------- | ------------------- | ------------------------------------ | -------------------- | ---------------------------------------------------- |
| **Microsoft Corporation KEK CA 2011** | June 2026 | Microsoft Corporation KEK 2K CA 2023 | Stored in KEK | Signs updates to DB and DBX. |
| **Microsoft Windows Production PCA 2011** | Oct 2026 | Windows UEFI CA 2023 | Stored in DB | Used for signing the Windows boot loader. |
| **Microsoft UEFI CA 2011\*** | June 2026 | Microsoft UEFI CA 2023 | Stored in DB | Signs third-party boot loaders and EFI applications. |
| **Microsoft UEFI CA 2011\*** | June 2026 | Microsoft Option ROM UEFI CA 2023 | Stored in DB | Signs third-party option ROMs |
It looks like my VM is not using the new certificates. When I check the secure boot status from within Windows guest, it says:
Secure boot is on, but your device is using an older boot trust configuration that should be updated. There is not yet enough data to classify your device for automatic update.
This page says if I see this message then:
Your device might need additional validation before the update can proceed automatically. Visit aka.ms/getsecureboot for more information.
The link takes me back to the original page linked above.
This made me think Windows update failed to work with QEMU's UEFI firmware called OVMF.
The XML tab of the Overview section of the Virtual Machine Manager shows in part:
<loader readonly="yes" secure="yes" type="pflash">/usr/share/OVMF/OVMF_CODE_4M.ms.fd</loader>
<nvram template="/usr/share/OVMF/OVMF_VARS_4M.ms.fd">/var/lib/libvirt/qemu/nvram/win11_VARS.fd</nvram>
The files OVMF_CODE_4M.ms.fd and OVMF_VARS_4M.ms.fd have the modified date of December 10, 2025. The file OVMF_CODE_4M.ms.fd is linked to OVMF_CODE_4M.secboot.fd in the folder /usr/share/OVMF/.
I looked at the OMVF UEFI configuration menu and couldn’t find anything regarding the secure boot certificates or anyway to add new ones.

My searches have led to some solutions for Red Hat, and Proxmox, but nothing specific to Ubuntu.
From the Linux perspective most solutions refer only to updating to the Microsoft UEFI CA 2023 certificate. I have not seen anything on how or if one should update the three other certificates expiring in 2026 when running Windows in a VM.
Q: How do I make sure that the OMVF is using all the secure boot certificates from 2023 so that Windows 11 works as expected beyond June 2023?
Thanks
installed Kubuntu 26 hoping to resolve a recurring problem when trying to install older Linux versions. I'm using a dual boot setup on an HP Omen with an Nvidia RTX 4070 and an i7 13th gen. The best I've managed is to boot by modifying the GRUB configuration with pci=noapic. This allowed me to access the desktop, install the proprietary Nvidia595 driver, and it works. However, the sound from the speakers and the headphone jack doesn't work. Only Bluetooth works. I want to be able to remove the noapic command and boot normally. I've already disabled Secure Boot and tried everything I found online (drivers, other boot modes, other variations of noapic, nomodeset, etc.). Is there a patch that will fix this? Is one planned?
I have a problem with thumbnails of graphic and video files on the desktop, I can't see their thumbnails. I only see the default icons of the files. How to fix it?
I'm in the US so a page is 8.5 inches by 11 inches ie. letter size orientation PORTRAIT
Whether it is an existing Writer document or a simple document of a few lines, it looks portrait oriented but when printed to a physical printer, it comes out in landscape orientation. Also a simple calc spreadsheet does the same thing.
Libreoffice as it comes with Ubuntu 23.10 or before (in my case that would be Ubuntu 22.04) - does not have the problem.
My printers are Canon iX6820, which are able to take paper up to about tabloid size - which is larger than the typical letter or legal size.
I'm hearing other large format printers, such as Epson Stylus Pro 3880 have a similar issue.
I'm running Ubuntu 22.04 in Windows 11 via WSL 2.0.4. Within Ubuntu, I've used sshfs to mount a remote directory to /media/remote1. My local Ubuntu user owns the mount point.
I want to access that mounted folder in Windows via the WSL network share. I can access the media folder in Windows Explorer (\\wsl.localhost\Ubuntu\media), but trying to access the mount folder results in pop-up an error saying "\wsl.localhost\Ubuntu\media\mount1 is not accessible. You might not have permission to use this network resource..."
The sshfs mounted folder is accessible from within Ubuntu.
I've also tried mounting it using a few variations of sshfs -o allow_other,default_permissions,ro but no luck.
What is needed to allow Windows to access a FUSE-mounted drive via the WSL network share?
When I run my C program on Ubuntu 20.04, I get this run-time error:
Segmentation fault (core dumped)
I really need to find and view the core file, but I can't find it anywhere. Where is it, and how do I view the backtrace in it?
I run win10 with 18.04LTS VM on virtual box. I am not experienced in VM's but have a need for Linux (personal use) so I thought vBox was the only solution.
I have 2 discrete graphics cards so I want to passthrough one of these to the Ubuntu VM (also for my application to leverage this, and to explore/learn from using the GPU HW).
I believe my hardware is all supported (CPU / 2xGPU's discrete / Motherboard w/VT-D) but I cannot find a clear guide for my goal: GPU passthrough to Ubuntu VM.
My questions:
Any other help or feedback would be greatly appreciated
Update: 5/31/2020
I just wanted to make clear that I am not using this environment for gaming. I work mostly from win10, but want to accelerate Matlab and Python inside my Linux guest w/GPU pass-through.
After some further reading, I'm unable to determine if virtualbox has any solution for my guest/host. Instead, it might seem VMware vSphere or Workstation-Player might support pass-through.
I am trying to remove/uninstall Firefox from Ubuntu 18.04. I have used sudo apt-get purge firefox. I have also deleted all the files I was told to delete for Firefox, but it is still there and opens.I don't like the new Firefox and don't want it. How can I remove it totally?
It isn't listed in the Software Apps, where you install or remove apps.
I have been trying to accomplish this task for years and every time I try it, I fail miserably and simply give up completely after Googling it and trying for hours. This time though, I decided to seek help from you!
Logically speaking, It should be a very straightforward simple task as follows:
Step 1: Right-click on the menu button, then go to "Edit Applications".
Step 2: Click on "Add new item", assign a menu entry name then create your launcher or command.
No matter how many variations of commands I try, it is never working out. I tried to launch the Konsole terminal then execute the command, but the Konsole is not holding still and closing automatically even after issuing the right flag to keep it running.
konsole -e anaconda-navigator --noclose
Specifying the command directly also does not work out and simply renders nothing on the screen.
anaconda-navigator
I wonder why it has to be very hard like that. Your help will be greatly appreciated!
My System Information - For Reference:
Title says it all, I've tried wifi-hostapd-app but I always run into trouble while installing one of its dependencies, dnsmasq specifically. I read one of the workarounds is to disable Ubuntu's Network Manager, I'd rather not do that.
I have a largish music collection and there are some duplicates in there. Is there any way to find duplicate files. At a minimum by doing a hash and seeing if two files have the same hash.
Bonus points for also finding files with the same name apart from the extension - I think I have some songs with both mp3 and ogg format versions.
I'm happy using the command line if that is the easiest way.
