Using the Raspberry Imager I am burning Ubuntu Core on to a CM5.

Strange issues.

First, using this link to download images https://cdimages.ubuntu.com/ubuntu-core/24/stable/ these are my results:

After burn and on first boot,

current build --> does not boot (sticks and loops around ubuntu flash screen not ubuntu core splash screen)

05-01 build --> works fine.

05-15 build --> works fine.

06-01 build --> same failure current build has (see above)

06-03 build --> same failure current build has (see above).

The CM5's I am purchasing are from PiShop. I have only had this issue with PiShop CM5's that I purchase. They do some sort of testing process that I believe may mess up partitions.

Any idea what is going on here?

Thanks, Will

I'm running Ubuntu 26.04 LTS and receive the following error during system updates:

Updating UEFI dbx results on internal error

Current version: 20250902
Latest Version: 20260402

does anyone know why widevine is not working for drm on older devices?

I have a lenovo b50 that no longer streams from ITVX, although some films seem to work, others don't. My dell optiplex 3020. 4th gen i5 with intel hd4060 graphics is also no longer being accepted by ITVX.

The browser, Firefox or Chrome, is displaying 'Update your browser'.

I'm trying to update my Ubuntu computer from 24.04.4 LTS to the latest LTS version (26.04), and along the way in that process I'm getting this error:

Could not calculate the upgrade 

An unresolvable problem occurred while calculating the upgrade. 

This may be caused by unofficial packages installed on the system. 
Please try replacing the following packages with official versions 
from the Ubuntu archive, and then try the upgrade again. 

gstreamer1.0-libcamera 

How would I go about removing libcamera so that I can update?

As requested this is the output of apt policy gstreamer1.0-libcamera:

gstreamer1.0-libcamera:

I had an issue I used AI to solve and thought I would pass it along. I followed all the advice but couldn't get my controller to work wireless. I will add the summary of diagnostic steps and solution below. I hope this helps someone. :

PS3 DualShock 3 Bluetooth on Ubuntu 24.04.4 LTS (Kernel 6.17)

Problem
-------
- Controller worked perfectly over USB.
- Bluetooth paired and connected but Steam never detected it.
- No /dev/input/js0 was created.
- bluetoothctl showed Connected: yes but Paired: no/Bonded: no.
- sixpair successfully programmed the controller with the PC's Bluetooth MAC.

Diagnostics
-----------
1. Verified hardware
   - USB controller detected.
   - hid_sony kernel module loaded.
   - Wired controller worked in Steam.

2. Verified Bluetooth transport
   - btmon showed:
     * ACL connection established.
     * HID Control (PSM 0x11) connected.
     * HID Interrupt (PSM 0x13) connected.
     * Controller transmitted HID reports (A1 01 ...).
   - Therefore Bluetooth and pairing were NOT the problem.

3. Verified device creation
   - udevadm monitor showed:
       add uhid
       add hidraw6
       remove hidraw6
   - HID device was created then immediately destroyed.

4. Found kernel errors
   journalctl reported:
       sony ... unknown main item tag 0x0
       sony ... Failed to set controller into operational mode
       sony ... failed to claim input

Root Cause
----------
BlueZ was using the UserspaceHID (UHID) backend, which failed to initialize
the DualShock 3 correctly on this system.

Fix
---
Edit:

    sudo nano /etc/bluetooth/input.conf

Set:

    UserspaceHID=false
    ClassicBondedOnly=false

Restart Bluetooth:

    sudo systemctl restart bluetooth

Ensure HIDP is loaded:

    sudo modprobe hidp

Reconnect controller:
    1. Plug USB in briefly.
    2. Unplug.
    3. Press PS.

Verification
------------
Successful fix produced:

    /dev/input/event27  PLAYSTATION(R)3 Controller Motion Sensors
    /dev/input/event28  PLAYSTATION(R)3 Controller

Controller became visible to evtest and Steam.

Useful diagnostic commands
--------------------------
btmon
bluetoothctl
sudo udevadm monitor --kernel --property
sudo journalctl -k -n 100 --no-pager
ls /dev/input/event*
ls /dev/input/js*
sudo evtest

Notes
-----
- sixpair is still required once to program the controller with the PC's
  Bluetooth MAC address.
- This controller is a genuine Sony CECHZC2U A2. ;

The Editing of the /etc/bluetooth/input.conf file as above was the solution. 

It simply freezes during installation and does not progress forward. I've tried different USB sticks, disabling Secure Boot, and nomodeset.

I have had many GPU problems in my current install of Kubuntu (I keep things as updated as possible). The previous GPU, an RX 580 8gb, had overheating issues (now found to be a hardware problem) and a system crashing issue, and now my RX 5500 xt 8gb also has a problem of randomly crashing in the game Cyberpunk 2077, and so far nowhere else. The game seems to be unstable on its own, as it can crash and glitch outside of graphics crashes. I am running it in medium graphics in windowed mode, on proton hotfix.

I have followed the guide "Dummy's guide to AMD GPU Issues", and besides enabling "amdgpu.gpu_recovery=1" in grub (which hasn't stopped crashing), this is the output I have been able to gather of all the goings-on in my system:

https://pastebin.com/knywXCRc

If needed, the crash that happens is that the game will freeze, the GPU won't send signal anymore and when it gives any signal it's all artifacts, the system being unresponsive.

I'm trying to figure out a concept on how to create a system that is installed on a RAID and has both encryption and self-healing (checksumming) capabilities, however, so far, I have failed to come up with a solution that has no issues.

Please consider the following as guidelines:

• A laptop (or other machine) that has two separate drives installed (SSD)

• Drives should be configured as RAID 1 against single drive failure, because unique data is saved onto them on the go (photos, videos, client's notes, passwords, etc.)

• RAID array should be able to boot in a degraded state, if absolutely necessary

• RAID array should be transferable, in case of laptop hardware failure (no hardware RAID)

• Data should be encrypted, because laptop is susceptible to theft and sensitive data should not be accessible by foreign parties

• (Strictly optional, but highly desired): Data should be safe against any form of corruption in the long term

I've read into a couple of different technologies that accomplish some of these criteria, but I can't make them work together to create a system that fulfills all of them. So far, I've considered:

md-raid: Does not know about data corruption, will brainlessly write any data to all active devices, whichever gets read first, gets loaded. RAID on top of encrypted block devices may fail to boot on single drive failure (?).

btrfs: Does not know about encryption. If btrfs is located on an encrypted md-raid device, it does not see individual underlying drives = no self-healing and no use for btrfs in the first place (in this specific scenario).

dm-crypt+dm-intergrity: No easy way of opening block devices (integritysetup) to boot the system, initramfs must be manually modified = no update-stability. RAID on top of encryption issue again.

ZFS: No native kernel support. Too... problematic to do.

Is there any other way to accomplish this that I have missed or anything that I got wrong? If somebody has done this before or knows of a configuration that would solve all these points, I would be glad to find a solution.

I'm trying to upgrade my Ubuntu Server to the latest LTS (26.04) from 24.04, but do-release-upgrade fails:

root@aragorn:~# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 24.04.4 LTS
Release:        24.04
Codename:       noble
root@aragorn:~# do-release-upgrade 
Checking for a new Ubuntu release
There is no development version of an LTS available.
To upgrade to the latest non-LTS development release 
set Prompt=normal in /etc/update-manager/release-upgrades.

I do not want a development release, so I left the prompt to lts in /etc/update-manager/release-upgrades

How can I do it?

I just upgraded my Ubuntu 24.04-4 MATE install to the latest version. I noticed that in Firefox the save dialog box refuses to save a file on the proposed location when hitting [Enter] like it always did. I first blamed Firefox but it is system-wide. Any GTK app has this unwanted behavior. Other PCs, a fully up-to-date Linux Mint 22.3 workstation and a fresh test install of Ubuntu 24.04 MATE on an HP USDT (Ultra Small Desktop) save just fine on [Enter].

But not only that, I also noticed files being overwritten without any warning when clicking Save (or using [Alt]+s). Barring a complete system re-install, how can I fix this?

I have a VPN connection configured in Settings > Netowork > VPN. I've entered the following values:

• Name: MyVPN

• VPN Protocol: Palo Alto Networks GlobalProtect

• Network gateway: https://vpn.mycomp.net

All the other values are left default, and are mostly empty.

Now, when I click connect, I am asked to log in. When I click the login button, The VPN window opens my company's log in page internally, inside itself. And this does not work, because the VPN window only supports password login, which is disabled by my company's administration, and as a result, I can never log in. What I must use instead, is passkey. The passkey login works fine through my default browser, which is Vivaldi. How can I rely on Vivaldi to log in my VPN connection?

I have atleast 1000 ubuntu servers running 18.04 with LTS support, Now i need to plan a phase wise approach to move from 18.04 to 22.04 and later plan for 24.x.

Manually updating each server takes a huge amount of time and the intended downtime associated with downloading of the packages and updating each library, kernel.....etc.

Can we replicate the upgrade packages that have been already used to upgrade lets say Server-1 and use it as a copy server to replicate across all other ubuntu servers, this saves a lot of time and bandwidth.

Ubuntu user

I have a dual boot setup with Ubuntu 24.04 and Windows 11, where each operating system is installed on its own dedicated SSD.

The issue is that after some time, GRUB completely disappears, and the computer boots straight into Windows 11. When I check the BIOS/UEFI settings, the Ubuntu partition/boot option is simply gone.

I can only get GRUB back by physically removing the Windows SSD and leaving only the Ubuntu SSD installed. After doing this and reconnecting both drives, everything goes back to "normal" for a while (though I notice that the Windows system clock gets completely messed up). However, after a short period, the Ubuntu partition disappears from the boot options all over again.

I have already tried several troubleshooting steps, including reinstalling and reconfiguring GRUB, but nothing seems to permanently fix the issue.

My hardware specs:

Motherboard: ASUS ROG Strix Z790-F Gaming WiFi  

NVMe 1: Windows 11  

NVMe 2: Ubuntu 24.04

Some relevant info...

When I list the disks and partitions in Linux, this is the output:

I tried to remove Ubuntu from window and install new Linux but the garb always pop out I think my file are still safe on window 10

I tried downloading Tuta AppImage but it doesn't run when I try to run it from file manager. I right click on the file and enabled running the file as an executable, and it still does not run. I intent to troubleshoot why it does not run, and it requires me to run it from the terminal so it will show me where it goes wrong. How do I run the AppImage file from the terminal?

Was looking up how to share my files between my two Ubuntu computers.

Found this question: How do I set up file sharing between two Ubuntu laptops on my wireless network?

But that's for 12.04. Very old. I have 24.04 and 26.04 LTS straight from the Ubuntu Desktop website.

Presuming the 12.04 was the most direct one as well, most minimal install the iso allows etc, do I still need to install openssh-server or anything, to move files over the network?

I am running Ubuntu 24.04. I was just using my laptop normally, and then suddenly the entire screen went dark. I realized that things were still happening in the background, and if i plug my laptop into a different display i can still see everything, and i can barely make out whats on the laptop screen by shining a flashlight on it. I have tried to enter recovery mode but i cannot see any of the menus since the my laptop doesn't put it on the separate display. What do i do?

Hi I installed amd graphics drivers on ubuntu 24.04 but when i go to settings -> Screen Display I still can not change the resolution. My monitor is 4K with 165 Hz, but it currently shows 3440x1400 and I can not change it.

amdgpu-install --usecase=graphics

My PC has no audio. I use Kubuntu 24.04 and KDE Plasma 5.27.12. I know nothing about computers. My monitor is a HQ 19.5". Apparently it has no audio output, but the audio also doesn't work if I try and connect earphones. I get audio only when I connect my CPU to the TV in the living room. Should I buy a new monitor?

Specifications:

   OS: Kubuntu 24.04
   KDE Plasma Version: 5.27.12
   KDE Frameworks Version: 5.115.0
   Qt version: 5.15.13
   Kernel version: 6.17.0-35-generic (64-bit)
   Graphics platform: X11
   Processors: 4 × AMD Ryzen 3 2200G with Radeon Vega Graphics
   Memory: 5.7 GiB of RAM
   Graphics processor: AMD Radeon Vega 8 Graphics

The audio system shows 2 outputs (HDMI and Pro Audio) which I can select with or without earphones connected, and I tested both with the earphones connected and there was no audio. I connected the earphones through the top and back connectors, and I tested with both outputs listed above. In the past I also tried connecting speakers to it, but it still had no audio.

I use Inkscape to run a vinyl cutter. Every time I try to use the cutter I have to change permissions using:

sudo chmod a+rw /dev/ttyUSB0

I believe there should be a way to set up permissions, possibly using groups, so that the permission is remembered and does not have to be changed every session. However, the information I have been able to find online seems to me to contradictory and confusing. I am wary of making changes without clear instructions as I am concerned about breaking other permissions.

When I run lsusb the entry for the cutter is:

Bus 001 Device 007: ID 0403:6001 Future Technology Devices International, Ltd FT232 Serial (UART) IC

I am using Ubuntu 24.04. I am the only user.

Is anyone able to help me with simple step by step instructions please? Any help is much appreciated, but needs to be simple as use Ubuntu as a means to an end.

First, thanks for the feedback. I'm embarrassed because IRL, I used to do QA.

I'm trying to install Ubuntu 26.04 LTS Desktop to an external SanDisk 4 TB SSD drive from a usb microsd card reader with a 28 GB card in it.

I get the "Something went wrong" screen. This happens with two different computers.

When I click the "Show Log" button, the only message that is displayed is "No journal files were found."

This is very reproducible.

I've also tried it with a PNY 128 GB flash drive. This installation got further but encountered an error during installation.

The download checksum verified successfully.

Is there any way to verify the installation media?

How I got there: I don't have a precise idea, I think it is a problem with updates. First I had problem with Alsa mixer. My sound didnt work when I wanted to watch a video. Each time I needed to reload alsa for the computer to emit sound. After I have some updates to do, the computer would shut down and I had to turn it back on, but no update was installed and it asked again every time I turned on the PC. This must have been going on for about two months. 5days ago it shut down and I can no longer exit the console screen when I turn on the PC. I can log in.

I'm a noob on Ubuntu, I don't understand and know a lot and how it works so I searched but found nothing to help me.

I want to return to the graphic screen, I think my data is dead but I would prefer to keep it if possible.

I am currently stuck on the console or tty screen. So I tried many commands to exit:

• CTRL + ALT + Fx

  (where x is between 1 to 12) it should work but no, I just change of screen but I don't quit.

• startx

  but that just gave an error:

Oh shoot ! Something went wrong. A problem has occurred and the system cannot recover. Log out and try again.

It doesn't work. Then:

  there is just a black screen now. I shut down with the button and it says

Have searched and found conflicting info..

Can Gnome on 26.04 run as an X11 session?

Or do I have to install/run XFCE or similar?

Mainly need this to run NoMachine on a headless server.

Thanks.

The default Super + something keyboard shortcuts don't work on my live session and even if I try to change it to some other shortcut key combination even not containing Super key, I can't get it work. No Super key combinations work in Window Manager settings, but some work in Keyboard settings. And Whisker Menu can be started by mere Super key release. Resetting to defaults didn't help.

I have bought a cheap new PC which I hope to put Ubuntu 24.04 or an official flavor as a sole operating system. The PC is an Acer XC-840 manufactured in September 2022 and still in box unused. Spec Intel N4505 processor ,4GB DDr4 Ram, 256 GB SSD , Intel UHD graphics , Bios R01-A2 . Hopefully this is able to run Ubuntu . I have never installed on other than very old computers and would like to know what I need to do to avoid failure . Do I need to run Windows first or can I Boot from a USB with Ubuntu ISO on and just select install using whole drive without disabling secure boot or making other changes beforehand ? As is probably obvious I am very much a beginner with Linux and would appreciate any available guidance.

When I type the command sudo python3 -m venv venv001 I get this error:

The virtual environment was not created successfully because ensurepip is not available.  On Debian/Ubuntu systems, you need to install the python3-venv package using the following command.

    apt install python3.8-venv

You may need to use sudo with that command.  After installing the python3-venv package, recreate your virtual environment.

Failing command: ['/home/mike/venv001/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']

so, I try sudo apt install python3.8-env and get the error message:

I've tried a couple of the sudo apt install -f, or --fix- commands, but still can't seem to recover from these errors.

after a reboot my Acer Laptop is stuck on a boot loop, in the upper left corner also appear the message "Reset System", I tried reinstalling ubuntu but this didn't solve the problem. I used boot-repair and pasted the log here:

What can I do? Thank you in advance

Whenever I boot up, my monitor's settings are always zoomed in about at 10, out of a scale of 0-100.

It also happens if I turn my monitor off and on again.

If I change my Display settings to rotate my screen orientation from Landscape to Portrait and back, but not Landscape to Flipped Landscape and back.

And changing the Scale in the Display Settings menu doesn't mess up the Zoom again, either.

I have a Dell SP2208WFP, and my Monitors.xml looks like:

<monitors version="2">
  <configuration>
    <logicalmonitor>
      <x>0</x>
      <y>0</y>
      <scale>0</scale>
      <primary>yes</primary>
      <monitor>
        <monitorspec>
          <connector>HDMI-A-1</connector>
          <vendor>DEL</vendor>
          <product>SP2208WFP</product>
          <serial>RR268831CT0U</serial>
        </monitorspec>
        <mode>
          <width>1680</width>
          <height>1050</height>
          <rate>59.954250335693359</rate>
        </mode>
      </monitor>
    </logicalmonitor>
  </configuration>
</monitors>

...

And now, Scale is reset to 1... Because I exited a fullscreen app or something??

...

It even happens in Recovery Mode, when I don't have a DISPLAY variable set.

...

But, it doesn't seem to happen if I connect through the screwy connection cables instead of HDMI...

Never mind. Updating might not have fixed it. I will have to test later. I was confused about what output I was using.

OS = Ubuntu 18.04 LTS PC = Lenovo Ideapad Y500 (released 2012) Wireless card = Intel Centrino Wireless N2230

I just installed Ubuntu 18.04 LTS on an old Lenovo Ideapad (notebook) model Y500. It works OK, but for WiFi to work, I have to provide these commands in a Terminal:

sudo modprobe -r iwlwifi
sudo modprobe iwlwifi 11n_disable=1

This works, but only for a little while. If the computer goes to sleep (or is rebooted), I have to give these commands again.

1. I have no clue what these commands do.

2. Whatever these fixes, I would like to make permanent.

3. When this works, WiFi speed is horrible (about 20 Mbps), but wired ethernet speed is wonderful (about 930 Mbps - I have fiber internet).

I have no clue what Ubuntu sees as my WiFi card. If this were Windows, I could look at the Device Manager and see what Windows thought it is (which can be wrong). With Linux, I'm too stupid to figure out what the OS thinks the card is.

Is it possible that Ubuntu is misidentifying my wireless card? If yes, can I fix this (and improve speed) by using a different driver?

As ZFS is now officially supported in Ubuntu 16.04, I would like to enable email notifications for my ZFS pool. Below are the steps I have taken so far, however I am now currently stuck:

• Installed msmtp and set it up to work with an external gmail account successfully.
• Uncommented and configured /etc/zfs/zed.d/zed.rc
• Set ZED_NOTIFY_VERBOSE=1
• Ran zpool scrub expecting to receive a notification of the clean scrub, no email is sent

This is the only post that I can find relating to ZFS/ZED configuration, however I was unable to get it to work: http://louwrentius.com/the-zfs-event-daemon-on-linux.html

Update: Both responses from Mumblepins and Martin led to the fix. Below are the full steps needed to get this to work:

• Install msmtp and set it up to work with an external email account (gmail or whatever)
• Install s-nail and msmtp-mta packages to map msmtp to the mail command
• Uncomment and configure /etc/zfs/zed.d/zed.rc (keeping ZED_EMAIL_PROG="mail")
• systemctl enable zed
