Ubuntu 26.04.
Suddenly I've got an error executing apt update. After days of searching in internet impossible to solve the problem. The error is:
W: An error occured during the signature verification. The repository is not updated and the previous index files will be used. GPG error: <URL> : Unknown error executing apt-key.
version: Ubuntu server 24.04.2
I have another server with the same keys and the same version and everything is fine. Listed with apt-key list.
I am really stuck with this do you have an idea on how to solve this?
I am currently using Kubuntu 25.10.
The problem is that when I turn on Wi-Fi and connect to a Wi-Fi network, after 2–5–10–15 (random) minutes, my system freezes (keyboard + touchpad + mouse + screen) with a fullscreen message "KERNEL PANIC", and then I have to force shutdown to restart the system.
So I thought there was a problem with Kubuntu 25.10. Then I tried using the latest Linux Mint (through a live USB) without connecting to a Wi-Fi network, and the moment I tried to connect to a Wi-Fi network, the system froze again. Then I became sure that the issue is not with Kubuntu 25.10.
So now I am still using Kubuntu 25.10 and using the internet with USB tethering through my mobile phone, and the issue is gone. I haven’t checked with Ethernet. So if I unplug the USB cable and turn on Wi-Fi, it automatically connects to an available network, and I can use the internet for a maximum of 2–5 minutes. Then the Wi-Fi automatically disconnects, but in the panel (Wi-Fi connected icon) it still looks like it is connected, and then the system freezes, displaying a message: “KERNEL PANIC.”
There are some outputs of useful commands:

I installed an Virtual Machine Manager but then got no connection to Qemu. I got the message that I should look, if an adequate libvirt daemon is running. What can I do? This is the full message:

What can I do.
I'm running Ubuntu in a VmWare VM. I have eliminated all snapshots and increased the size of the disk in the VM. What do I need to do to use the additional space?
I've got bind9 installed and it's working just fine. All nslookup and dig commands work, checkconfig all of that.
I just want any unresolvable requests to go to Google.
Here's /etc/bind/named.conf.options:
options {
directory "/var/cache/bind";
forwarders {
8.8.8.8;
};
dnssec-validation auto;
listen-on-v6 { any; };
};
I'm not sure what else I need to do.
The requests are not sent to 8.8.8.8. I verified that in Wireshark.
Authentication Prompts to Install Unknown Software:
An icon appears on my hotbar (KDE/Kubuntu) when I first log in after rebooting my computer. It looks like a speech bubble with an ellipsis in it. Clicking on this brings up this pop-up asking for authentication to install... something. I have no idea what it is, but have been worried it might be malware (thus I always cancel, and it goes away). I've been using Kubuntu for several years, and Linux for longer, but have never seen anything like this. It doesn't seem related to Dolphin or the normal updates.
Does anyone know what it is? If it is a threat, anyone know how to get rid of it (I'm tired of seeing it every time I restart my computer)?

I'm not sure what happened, but I am running 4 Dell Optiplex machines and they all have the same problems going back several weeks. General slowness, choppyness, high CPU, slow load times on web pages and so on. The telltale sign is choppy mouse that freezes momentarily when a tooltip pops over the GUI or when the machine is processing.
All machines are from the Dell Optiplex series. They all have integrated, Intel video cards. They're all running 24.04. I've tried rolling back the kernel, switching from Wayland to Xorg, and disabling Gnome extensions. I have not read of others having this specific problem but it can't be a coincidence if it happened to all my machines at the same time. Any ideas how to fix this?

Can anyone recommend some good disk data recovery software for Linux? I have a 4 Tb disk that was my primary Ubuntu 22.04 drive about 3/4 full that has a damaged GRUB and wouldn't boot. I spent about 2 weeks trying every repair command line strategy Google could come up with without any success. As a last resort I re-installed Grub from the installation USB. Now it boots but doesn't access any of the 257,410 items that 'properties' describes as unavailable. I presume that means I have overwritten some or all of my root directory. I have a new installation of Ubuntu 24.04 on a different computer with a larger drive so I have a safe place to put any recovered files. All the recovery software that Google comes up with seems to be for Mac and Windows and runs on Mac or Windows. I have 5 different flavors of Linux but no Mac or Windows. Any suggestions would be welcome.
User68187 asked what flavors of Linux. Ubuntu22.04 and 24.04, Mint 22, and LMDE7; all in desktop PC's. LinuxCNC (Debian 14) and BeagleBone black (Debian 12.13),in two dedicated non-PC machine controllers.
I am about 3-4 weeks new to Ubuntu, downloading it in a bid to not install Windows 11, and for those weeks I've been trying my hardest to get my Steam games working on this device, to no avail.
Some games do work. I was able to get PEAK working on my computer after a LOT of setup, and single player games/really old point and clicks (e.g. Dave the Diver, Sam and Max Hit the Road, IHNMAIMS) work perfectly (though this could just be because of how simplistic they are).
Games such as Deadlock, Marvel Rivals, and The Outlast Trials, more high-fidelity games with a high amount of multiplayer however don't boot up. The best I've gotten is Deadlock, which I've been able to get the launch screen up until it crashes. Unfortunately all the answers I've seen on this website are either not working, or are simply too complex for my newbie brain to comprehend. I have gamemode installed and configured, GeProton is installed and applied to all desired games, ProtonTricks is installed, though I have no idea idea how to use it, and my Driver package is nvidia-driver-535.
Here is the last terminal log I recorded with Deadlock, gained by running Steam through Terminal. If I had to guess what the problem was, it would be the system is not recognizing libgamemode.so, despite it being on the device.

Please help me with this. I'm at my wits end, am not going back to Windows for the life of me, and I not really welcome to the idea of booting another OS such as Arch and drafting all my files to that system just to have a better chance. It's already been a pain in the ass just to get Ubuntu working.
I use KDE Connect between my phone and laptop on my University WiFi. Very often, the IP address changes and the connection stops working. I have to manually find the IP of the computer with the command ip address and put it in my phone and connect manually. The same thing happens when I connect to a different network.
Is there any way to automate the connection process? AFAIK know Apple's computers have some robust connection procedure with iOS devices.
I want to be able to do this for multiple computers with the same phone.
Cannot get security updates. This is the message i got

I have a Lenovo IdeaPad Slim 5 16HAP9 that is running Ubuntu 24.04.3 LTS. With some regularity the track pad will partially stop working. The symptoms are not always the same but commonly include inability to left or right click, loss of 2 finger scroll, and increased cursor sensitivity (moves much faster). I can always move the cursor and sometimes left mouse click still works. The laptop has a touch screen which continues to function properly.
If I reboot the track pad will continue working for some indeterminate amount of time before the issues reappear. I have not found a predictable cause. It seems very random.
I can also get the track pad to work again by reloading the driver.
sudo rmmod hid_multitouch
sudo modprobe hid_multitouch
Are there ways to find errors or log messages that can give me some hint as to what is causing the issues and how to fix it?
On my lubuntu 24.04 distribution I have installed the hypervisor Oracle VirtualBox 7.1.6 and I have imported a Virtual Machine (called my-virtual-machine below in this question).
I have found how to start and power off a Virtual Machine by command line:
/usr/bin/VBoxManage startvm 'my-virtual-machine' --type gui
/usr/bin/VBoxManage controlvm 'my-virtual-machine' acpipowerbutton
I have the following needs:
my-virtual-machine (the Guest) automatically at boot time of my Host (that is lubuntu 24.04)my-virtual-machine at the shutdown of the HostBy this post, which is very old and refers to VirtalBox 4.2 but seems yet valid for VirtualBox 7.1, I'm able to solve my first request and perhaps the second request.
The problem is the third request because the method explained by the post allows to start the virtual machine at boot of the Host system but in headless mode and not with the GUI.
When the Vitual Machine is correctly started I can see the following 2 process by ps aux command:
> ps aux | grep VBox
[...] /usr/lib/virtualbox/VBoxHeadless --comment my-virtual-machine --startvm 546632bd-b8bd-4f2d-b2a1-8657b968378a --vrde config
[...] /usr/lib/virtualbox/VBoxSVC --auto-shutdown --inherit-startup-pipe 7
How to start a Oracle VirtualBox VM with GUI (and not headless) at boot time of the Host system and power off the VM at the shutdown of the Host system?
After the upgrade I have noticed that dragging a file to WPS office window in order to open it leaves behind a ghost icon stuck on the screen above all windows:
Ghost icon:
Using nautilus -q solves the problem, but it is generally annoying and I have no clue how to debug this behavior.
##Please see output at this link https://termbin.com/nru6.
I have looked at https://github.com/lwfinger/rtw89 and tried it but it doesn't work. It also says this in the description.
"This code will build on any kernel 6.10 and newer as long as the distro has not modified any of the kernel APIs. IF YOU RUN UBUNTU, YOU CAN BE ASSURED THAT THE APIs HAVE CHANGED. NO, I WILL NOT MODIFY THE SOURCE FOR YOU. YOU ARE ON YOUR OWN!!!!!"
Any help will be appreciated. Thanks
Ubuntu is not opening after removing Windows from the laptop.
I cannot see grub and a black screen, and the only thing on this screen is: Reset System. Please help me with this.

Sometimes I need to edit files in /etc. I know I can do this with the console (sudo mv some/file /etc/some/file, sudo nano /etc/some/file) etc, but I find this way a bit clunky. Call me spoiled, but I'm really used to GUI tools such as Nautilus and Gedit.
Distributions such as Ubuntu Mate or Mint make it easy: I can right click a folder and then a context menu appears with options such as "open as administrator". From then double-clicking a text file opens it in gedit with elevated privileges.
However, I can't find such an option in the default Unity version of Ubuntu:
Note:
gksudo, which no longer workssudo gedit /etc/whatever, but - AFAIK - using sudo with GUI tools is heavily ill-advised
Is there a way to run Nautilus or Gedit with elevated privileges?
Online I found the following figure where you can see "CPU" as first row, and it should represent the total amount of the used CPU.
Amongst the options of the htop I run on my PC there isn't the above CPU option. Where can I find it?

I was trying to update and I got to this. I'm not sure what to do.
I would like to start a python script from a virtual environment on startup. I have searched the whole forum and other sources but have not been able to make it work.
The script should run at the scripts directory as working directory and also the terminal that started the script should be kept visible.
I have mainly used the "Startup Applications" and different configurations of .desktop files in ~/user/.config/autostart
I have tried with running shell files that work on their own as the below:
[Desktop Entry]
Type=Application
Terminal=true
Exec=/home/user/autostart.sh
Hidden=false
NoDisplay=false
X-GNOME-Autostart-enabled=True
Name=autostart_shell
Comment=
And the .sh-file
#!/usr/bin/env bash
sleep 10
cd /home/user/environment
bin/python3 main.py
bash
or something like this
#!/usr/bin/env bash
sleep 10
cd /home/user/environment
source bin/activate
python3 main.py
bash
However the environment never gets activated.
I have also tried other .desktop-configurations as below without success
[Desktop Entry]
Type=Application
Path=/home/user/env/
Terminal=true
Exec=gnome-terminal --command 'bash -ec "sleep 10;cd /home/user/env;source bin/activate;python3 main.py;bash"'
Hidden=false
NoDisplay=false
X-GNOME-Autostart-enabled=true
I've spent most of the day on this without any success, does anyone have any ideas?
UPDATE Ok, after some more work the problem is related to activating the virtual environment.
I'm using the "Startup Applications" to run a shell script. I have tried both the gnome-terminal and xterm with the same result. Below is the command in the *.desktop jobs
gnome-terminal --command '/home/user/folder/startup.sh'
and
xterm /home/user/folder/startup.sh
The shell script looks as follows:
#!/bin/bash
# Give it some time to make sure everything is loaded
sleep 5
# Logging to make sure it is run
TIMESTAMP=`date "+%Y-%m-%d %H:%M:%S"`
echo "$TIMESTAMP - program was run " >> /home/user/folder/log.txt
# Switching working directory
cd /home/user/folder
# Alternative 1
# Run python script with virtual envirnments python binary
/home/user/folder/bin/python3 /home/user/folder/main.py
# Alternative 2
# Activate environment and then run
source /home/user/folder/bin/activate
python3 /home/user/folder/main.py
# Keep the terminal open
bash
On boot and login the terminal is launched but a python error is displayed about a missing module. If the shell script is run standalone it works without a problem, but launched from the "Startup applications" it is not.
This is nagging me so hard, is it really not possible to start a terminal in a python virtual environment?
I recently set up Ubuntu server 18.04 LTS on an old laptop to use as a Plex Media server, and wanted to connect it to my existing media share on my QNAP NAS. I set this up using CIFS, and it seems to work, but every now an then i get the following message appear on the screen.
CIFS VFS: Free previous auth_key.response = 0000000076b9d676
The number at the end always changes. How do I get rid of this message??
Btw here is how I setup access to the share
sudo apt install cifs-utils
sudo mkdir /mnt/nas_media
cat > ~/.smbcredentials
username=myusername
password=mypassword
ctrl+c
sudo chown root ~/.smbcredentials
sudo chmod 600 ~/.smbcredentials
id -u plex
I'll be using 113 as the UID for this example
sudo cp /etc/fstab /etc/fstab-old
sudo vi /etc/fstab
press i to enter insert mode go to end of file and enter a new line add the following
Note ip, sharename and username have been changed for privacy. Also vers=3.0 was set because that is the version of samba I have set on my nas.
//192.168.1.50/MyShare /mnt/nas_media cifs vers=3.0,iocharset=utf8,credentials=/home/myusername/.smbcredentials,uid=113 0 0
type :wq to save and exit vi
mount -a
btw I've also rebooted the server and the message always comes back. Plex is able to read and write to the share, so I'm not too sure why this message is coming up.
Is there anything I missed?
I am working on a project where we have built (for free of course) some computing labs on middle-high schools by the use of some old computers running Edubuntu via LTSP software framework. The LTSP clients are thin clients.
Everything worked fine until we upgraded our server from Edubuntu 12.04 to 14.04. Then some thin client stopped working going on a sort of kernel panic during bootstrap. The strange thing is that a live of Edubuntu 14.04 booted via USB works fine on these clients. The problem involves just a subset of our computers, in particular the ones who share the same architecture(you can see the lshw next).
In particular, the error messages are the following:

Does anyone have some tips or had the same problem? Tell me if you need other information about the problem.
I followed the first answer here: How do I get an XBOX 360 controller working?, and ended up screwing with my XPad drivers. How can I reverse all of the commands and restore my XPad Driver?
I used these commands:
sudo apt-get install --install-recommends jstest* joystick xboxdrv
echo "blacklist xpad" | sudo tee -a /etc/modprobe.d/blacklist.conf
sudo rmmod xpad # unload module if already loaded
xboxdrv --silent
jstest-gtk
Then I edited /etc/init/xboxdrv.conf and added
start on filesystem
exec xboxdrv -D
expect fork
I am struggling to get this to work properly.
This works in terminal
sudo bindfs -u dave /media/dave/Documentary2Lin/RAIDMain/Documentary2 ~/shares/Documentary2
How do I get this to work in fstab?
I've tried
/media/dave/Documentary2Lin/RAIDMain/Documentary2 ~/shares/Documentary2 fuse.bindfs force-user=dave perms=a=rX 0 0
It gives an error in fstab

I'm writing a simple bash script, but I need it to check whether it's being run as root or not. I know there's probably a very simple way to do that, but I have no idea how.
Just to be clear:
What's a simple way to write a script foo.sh, so that the command ./foo.sh outputs 0, and the command sudo ./foo.sh outputs 1?
