I'm using Ubuntu 24.04 LTS and I want to install Node.js 22 using the official NodeSource repository instead of the default Ubuntu package. I tried installing Node.js using: sudo apt update sudo apt install nodejs However, it installs an older version than I need.

My questions are:

What is the recommended way to install Node.js 22 on Ubuntu 24.04? Should I use NodeSource or another official method? How can I keep Node.js updated in the future? Is there any risk of conflicting with Ubuntu packages?

I have searched the Ubuntu documentation and several online guides, but I'm looking for the recommended approach from experienced Ubuntu users.

Bellow is the issue I am getting while installing packages using snap example Firefox is mention bellow. Can someone help me in this? is it related to organization certificate or Ubuntu?

Ubuntu 26.04 Freezes After Playing or Exiting Friday Night Funkin

System Information

Operating System: Ubuntu 26.04 LTS Laptop: HP EliteBook 845 G8 CPU: AMD Ryzen Processor GPU: AMD Radeon Vega 7 (Integrated Graphics)

Issue Description

I'm experiencing a system freeze whenever I play Friday Night Funkin. The game itself appears to run normally while playing, but after exiting the game—or sometimes shortly after gameplay—the entire desktop becomes unresponsive.

The freeze affects the whole graphical session, making the system unusable until I force a reboot.

The desktop freezes after playing or exiting Friday Night Funkin. The display becomes unresponsive. A forced reboot is usually required to recover the system.

Hardware Information

Device: HP EliteBook 845 G8 Graphics: AMD Radeon Vega 7 (Integrated)

Possible Cause

Since the issue only occurs after running the game, I suspect it may be related to:

Wayland or X11 display server compatibility GPU reset or display rendering issue triggered after the game exits

However, I'm not certain whether this is a graphics driver problem, a Mesa bug, or an issue specific to Friday Night Funkin'.

Troubleshooting Request

Has anyone experienced a similar issue with AMD integrated graphics on Ubuntu?

I would appreciate guidance on:

How to identify whether the problem is caused by AMDGPU, Mesa, Wayland, or the game itself. Which log files or diagnostic commands should I check. Whether there are any known compatibility issues between Ubuntu 26.04 and AMD Radeon Vega 7 when running Friday Night Funkin'. Any recommended fixes or workarounds to prevent the desktop from freezing after exiting the game.

Any suggestions or debugging steps would be greatly appreciated. Thank you!

Among snap folders in 26.04LTS x64 Desktop there are 116 files which have the text \x2d embedded in their names - why? ordinary bash utilities such as tar and stat are having trouble with these files, in a backup utility I am writing.

Why embed a backslash code in a pathname?

Yesterday evening I updated my Ubuntu operating system, and then it requested a restart. I did that, and I lost everything that I had changed in the desktop appearance, so when I tried to refix that, it showed "Report a bug to Launchpad". How I can solve this issue? Is there any technical team that looks into my system and provides me with the solution in one go? I tried many times, but I cannot get it to work correctly because it does not appear in the settings, rather it shows Report to Launchpad.

The only difference between current/selected/highlighted icons in the Alt+Tab switcher is only few percent of gray intensity for background color, which is only visible under ideal lighting condition. If I use any of my 2 laptops in a bright environment with a screen positioned at a slight angle (to reduce glare) then there is no way to see which application is selected/highlighted in the Alt+Tab switcher window. This looks the same on Ubuntu 24 and 26, with Light or Dark theme selected, with high contrast accessibility setting enabled or disabled.

My problem is not just with yaru, which unfortunaterly uses close to 50 shades of gray to represent states of objects and it is impossible for human eye to see so many shades, but with gnome/ubuntu, which makes it super hard to modify that setting. I wasted days begging ChatGpt and Claude to give me instructions on how to change that and all I got was one hallucination after another, some of them prevented system from loading and requiring reinstall.

Finally, with help from Claude, I came up with the following procedure, which works:

# On the first run make backup of the original resource
RESOURCE=/usr/share/gnome-shell/theme/Yaru/gnome-shell-theme.gresource
RESOURCE_ORIG=${RESOURCE}.bak # Original
if [ ! -e ${RESOURCE_ORIG} ]; then
  echo "sudo cp ${RESOURCE} ${RESOURCE_ORIG}"
  sudo cp ${RESOURCE} ${RESOURCE_ORIG}
fi

WORK_DIR=~/temp
mkdir -p ${WORK_DIR}
rm -rf ${WORK_DIR}/*
cd ${WORK_DIR}

# Extract original resource to ~/temp directory
while IFS= read -r gpath; do
    local_rel="${gpath#/org/gnome/shell/theme/}"   # strip prefix
    mkdir -p "${WORK_DIR}/$(dirname "$local_rel")"
    gresource extract "${RESOURCE_ORIG}" "$gpath" > "${WORK_DIR}/$local_rel"
done < <(gresource list "${RESOURCE_ORIG}")

# Patch several "background-color" items under various "switcher-list" elemwnts, not clear which of them are really used
BACKGROUND="rgba(255, 255, 255, 1.0)"
PATCH_CSS=("gnome-shell-dark.css" "gnome-shell.css")
for css in "${PATCH_CSS[@]}"; do
    f="${WORK_DIR}/Yaru/$css"
    sed -i '/\.switcher-list \.item-box:selected {/{n;s/background-color: [^;]*;/background-color: '"$BACKGROUND"';/}' "${f}"
    sed -i '/\.switcher-list \.item-box:highlighted/{n;n;s/background-color: [^;]*;/background-color: '"$BACKGROUND"';/}' "${f}"
    sed -i '/\.switcher-list \.item-box:highlighted/{n;s/background-color: [^;]*;/background-color: '"$BACKGROUND"';/}' "${f}"
done

{
    echo '<?xml version="1.0" encoding="UTF-8"?>'
    echo '<gresources><gresource prefix="/org/gnome/shell/theme">'
    find "${WORK_DIR}" -type f | sort | while read -r f; do
        echo "  <file>${f#${WORK_DIR}/}</file>"
    done
    echo '</gresource></gresources>'
} > "${WORK_DIR}/theme.gresource.xml"

# Compile
(cd "${WORK_DIR}" && glib-compile-resources theme.gresource.xml)

# Deploy
sudo cp "${WORK_DIR}/theme.gresource" "${RESOURCE}"

# Reboot (or re-login)
sudo reboot

This works:

But it cannot be so complex!

Also, Claude suggested that there should be a way to modify the Yary theme locally instead of system level, but so far I did not get working instructions.

Is there a better way? Any suggestions?

(By the way, Windows simply paints a thin white rectangle around the selected icon, which is always perfectly visible).

Thank you

I also posted this question at https://github.com/ubuntu/yaru/issues/4477

I upgraded to Ubuntu Resolute (26.04) on a Dell XPS 13 Plus and now the camera and built-in microphone don't work.

System info:

• Dell XPS 9320 (13 Plus)
• Ubuntu Resolute (26.04)
• Kernel: 6.8.0-45-generic
• Intel Raptor Lake processor

What I've tried:

1. Installed intel-ipu6-dkms - failed to compile: v4l2_find_nearest_size_conditional function doesn't exist in kernel 6.8.0-45
2. Added ppa:oem-solutions-group/intel-ipu6 and installed linux-modules-ipu6-generic - no change
3. Blacklisted mei_vsc and mei_vsc_hwem modules - still failing

Current error:

[   15.985162] pci 0000:00:05.0: deferred probe pending: intel-ipu6: IPU6 bridge init failed

Audio devices load but produce no sound. Camera app gets no device.

dmesg output:

[    3.106500] intel-ipu6 0000:00:05.0: enabling device (0000 -> 0002)
[   15.985162] pci 0000:00:05.0: deferred probe pending: intel-ipu6: IPU6 bridge init failed

Is this a known issue with Resolute on XPS 13 Plus? What's the fix?

I've been trying to wipe my drive and reinstall Ubuntu after it had a kernel panic I couldn't explain. I keep trying to use a USB to load it into my computer now that the drive is wiped, and it keeps freezing once I get to the Try or install Ubuntu screen and I try and start the service. Do you have any pointers? It has never been this hard for me to download Ubuntu before.

I'm getting angry with my Ubunutu 18 (higher versions don't work me beacuse are freezing)

So... from a few days ago after updated firefox I'm struggled with internal keyboard of my Acer Aspire ES1-331:

internal keyboard sometimes get completytely disabled or is ignoring some keys (s, r, y, backspace, enter) or delays a lot, sometimes OS gets frozen. Sometyimes I'm not able to type just password on login, sometimes not. Generic solutions over internet doesn't help. USB plugged keyboard is OK, internal keyboard too untill that update.

I tryed to reconfigure keyboard with dpgkg config, but problem still persists - may I'm using incorrect model, but can't find which one is that my one - ther're like five or six models for acer. Switching to generic keyboard doesn't fix anything.

Same with switching from wayland to xorg - doesn't fix anything.

My System

1. version of Ubuntu 24.04.4 LTS

2. GPU hardware name/model

Because the screen size is 640x480 I can only see partial dialogs. Dialogs with interactive buttons are off screen. There is no known (to me) method to views dialogs that require a space larger than 640x480 pixels.

I believe I have a Nvidia GeForce 1080 GPU but due the above condition I am unable to check this.

At the time when the screen size got stuck at 640x480 I was NOT updating anything. I was only using the computer in normal ways that users use computers.

At the time when the screen size got stuck at 640x480 I had unusual problems with my external USB drive not functioning correctly and acting weird. This led to rebooting my Ubuntu machine. This is when the resolution got stuck at 640x480.

At the time when the screen size got stuck at 649x480 I tried updating my Ubuntu machine thinking this may fix the problem. Things got worse. The updater couldn't accomplish certain things and gave errors. Due to the above condition I am unable to describe what these problems were for lack of visuals (i.e. dialogs off the screen).

I'd rather not reformat the entire system - but this may be the only option.

UPDATE 1:

After reading random solutions on the internet I have this really bad feeling that it's 100% impossible for me to fix this. If my system has recently updated to something absolutely incompatible with my GPU card then I guess I'm just hosed. There's no way I'll be able to "hack" a driver as others have suggested.

This is why I've always been against upgrades - especially when nothing was broken to begin with. At the very least there should be some method to roll back to the previous state if some problem like this were to occur.

EDIT 1 & 2 - (A) added Ubuntu version (B) added descriptive text. (C) deleted a paragraph (D) Deleted and added text at top

I recently installed Ubuntu 26.04 on my MS Surface 2 laptop. I was having issues with the wireless connection so I downloaded & updated the MS surface kernel. I would tell you specifically which one, but upon reboot, it sends me to a black screen with itty bitty font in the upper left corner of the screen saying:

Ubuntu 26.04 LTS (name)SB2 TTYL

(name)SB2 login:

(I input "y" & get this option next)

Password:

When I use either of the pass-phrase or the password, it tells me it's incorrect & just repeats the prompts. I can't figure out what to do to either bypass or fix this screen. Any ideas?

PS - would love to give you the kernel but I used my laptop to find & paste it. so....I can't access it now. 😬

I have Lenovo G570 laptop with 256ssd and 6GB ram. i already using Ubuntu 25.10. i install blender but when i run it the laptop shutdown. I install synfig and it's work smoothly

When I try to do so, a page appears with signs and symbols, in no case a package of files.

I will appreciate your help.

Release 26.04; AMD, all partitions are ext4

I have situation where I can boot in SSD 1 (I freshly installed Ubuntu 26.04 into here). No problem!

However I have my / and files on SSD 2. (This was extracted from an original PC and I have extracted the contents from the original partition [ encrypted and LV partition] into SSD2.

I have changed /etc/fstab from SSD1 / partition to SSD2 / partition by changing the UUIDs. On rebooting it does NOT boot into the SSD2 but boots again into SSD1 / partition.
My brain is fried after figuring out the extraction. BUT....I need to invoke some thing to ensure the booting is from SSD2. Need help....:)

Using the standard guides, I was able to set up an ubuntu 24.04 server to use secure LDAP with google client certificate, I even got it working with Ansible (ansible vault for storing the secret key). This means setting up sssd.conf and other basic configuration files.

But this does not work with 26.04. When I check the logs, sssd_be stays offline and says it cannot authenticate with Google's ldap servers. I have tried many things including using Claude to suggest tests and read the debug logs.

Does anyone have U26.04 + Google LDAP working? Was there some special trick required?

Are any additional steps required after apt upgrade to the next version?

So, I installed Ubuntu 25.04, then used dd to create 13 identical servers, changing machine-specific settings. Later, I upgraded all of them to Ubuntu 24.10 without any problems.

I have now started upgrading them to Ubuntu 26.04 LTS. The upgrade succeeded on 9 out of the 13 servers, but the remaining 4 refuse to upgrade.

user@server:~$ sudo apt update
user@server:~$ sudo apt upgrade
user@server:~$ sudo apt full-upgrade
user@server:~$ sudo apt autoremove
user@server:~$ sudo apt install --reinstall distro-info-data ubuntu-release-upgrader-core
user@server:~$ sudo apt install update-manager-core
user@server:~$ sudo reboot

After reboot:

How did I eventually perform the upgrade?

I restored /etc/apt/sources.list.d/ubuntu.sources, replacing old-releases and oracular with the normal archive, security, and resolute repositories, and then repeated the following steps:

user@server:~$ sudo apt update
user@server:~$ sudo apt upgrade
user@server:~$ sudo apt full-upgrade
user@server:~$ sudo apt autoremove
user@server:~$ sudo apt install --reinstall distro-info-data ubuntu-release-upgrader-core

After reboot:

I am trying (for about 3 days) to install an Ubuntu 24.04 LTS desktop with these requirements using the graphical installer:

• LVM
• Encrypted storage
• Swap (also encrypted)
• Manual partitioning

Both ChatGPT and Gemini had me believing that this was possible but after days of wrangling it seems it isn't. So can someone with lots of experience in this area please confirm/debunk that this is possible at least so the AIs can pick it up and correct themselves.

If the above is not possible with the graphical installer, what is the closest (as I write I am downloading the server ISO to give that a shot ...TIA) ?

PS: Yes there exist questions that come close to what I am asking here but they usually wander away into manually setting up most of it which is not practical for repeated use.

I have the new Terminal by Ptyxis and the old gnome-terminal both in my Ubuntu 26.04. When I push Ctrl+Alt+T the old gnome-terminal appears. How to switch to modern Terminal by Ptyxis? I can call Terminal by Ptyxis manually, but I want to use Ctrl+Alt+T, and I don't want to remove gnome-terminal.

I have tried this without success:

$ sudo update-alternatives --config x-terminal-emulator
[sudo: authenticate] Password:  
There are 2 choices for the alternative x-terminal-emulator (providing /usr/bin/x-terminal-emulator).

  Selection    Path                             Priority   Status
------------------------------------------------------------
* 0            /usr/bin/ptyxis                   40        auto mode
  1            /usr/bin/gnome-terminal.wrapper   40        manual mode
  2            /usr/bin/ptyxis                   40        manual mode

Press <enter> to keep the current choice[*], or type selection number:

Then pressed enter key. But Ctrl+Alt+T still calls old gnome-terminal.

My professional laptop Dell Precision is under Noble 24.04 installed after delivery (delivered under Jammy).

I am french so I used fr (bepo) keyboard layout.

I stay with X11 to use Gimp, have no issue with web-conferencing app …

Early may

I still had kernel update (6.17.0-22) that switched me under wayland and qwerty keyboard layout, I run in CLI: setxkbmap fr bepo that returns me: WARNING: Running setxkbmap against an Xwayland server, I swithed back to kernel 6.17.0-20 and X11.

This morning (17th jully)

After a first use, my laptop locked up after being idle for a while, then when I entered my password, I can't connect… it switched to qwerty. I also connect to the docking station to have external screen, but it stayed black, no external screen detected in display parameters. I had no more wifi connection, I should connect by cable.

I didn't find under grub connection to switch back to X11, so I switched in /etc/gdm3/custom.conf the WaylandEnable=false, but if I switch with success to X11, I still had no wifi, external screen.

I've recently updated my system through the "Software Updater" app.

After restarting the system the screen resolution was wrong, much smaller than expected and if I look among the Settings I am not able to choose any other screen resolution.

Previously, I was able to solve it by playing around with the settings in the "Software & Updates" app (NB: which is different from "Software Updater").
Apparently, Canonical has decided to remove it from newest versions of Ubuntu (see more: https://www.omgubuntu.co.uk/2026/02/ubuntu-26-04-drops-software-and-updates-gui).

What else can I do to solve the problem?

Given a local package name, I would like to open the corresponding Launchpad project in the browser. apport-bug supports this, but requires first filing a bug. I would like to go on Launchpad to read the changelog or search for duplicate bugs.

My current manual workflow is this: Retrieve the package name from dpkg -S /path or apt list --upgradable. Convert to a project name if dpkg -s packagename has a Source: line. Manually type in https://launchpad.net/ubuntu/+source/projectname in Firefox.

I would like mycommand subcommand [pid | packagename | program path] to automatically open that one Launchpad page. Launchpad sometimes takes a few seconds to load, so I don't want to need to visit multiple Launchpad pages. Is there a built-in command that supports this?

Furthermore, the Launchpad.net search feature suggested by @user1898883 is broken. https://launchpad.net/+search?field.text=aspnetcore-runtime-10.0 and https://launchpad.net/+search?field.text=dotnet10&field.actions.search=Search both return the unrelated https://bugs.launchpad.net/bugs/10 and https://answers.launchpad.net/ubuntu/+question/10 .

I am using Ubuntu 24.04 with English and Japanese keyboards: gsettings get org.gnome.desktop.input-sources sources gives [('xkb', 'us'), ('ibus', 'mozc-jp')].

The Japanese layout can input roman letters (capital A sign is in top-right corner of the screen); or hiragana (hiragana あ is displayed in top-right corner).

The problem is, that while I can reliably switch with super + space from English to Japanese, I can only switch back, if the Japanese layout is set to roman letters. Switching back from hiragana to English occasionally might work, but usually does not.

In a terminal screen, having hiragana active, the combination super+space almost always results in a space (that is: as if the super key were ignored completely).

I might have read somewhere that "this has to do something with 2-byte character encoding", but I can't seem to find the source right now. This was not an issue prior with Ubuntu 22.04.

I am using Ubuntu 20.04 with kde plasma. All of a sudden, my Dolphin file browser takes forever to open. Earlier it opened instantly, but now it is taking almost 30 seconds to start.

This seems to have started after an update; when I use kernel 5.11.0-38-generic there is no issue: the problem occurs when I use kernel 5.11.0-41-generic. In addition when on 5.41 the whole system seems to run slower.

When I run dolphin from the command line, there is no error output, and it is as slow as before to open.

I am using an Intel 4690k CPU with 16GB ram and SSD. I checked my drive health and it is fine.

Well, the title says it. I have a Lenovo yoga 500, recently updated to 20.04. When I was on 19.10, the keyboard used to show automatically when I touch a textbox. However, now it won't open, unless I do it manually via the Universal Access menu. I'll be happy If someone can help me.

I have a problem with Ubuntu 14.04. Suddenly, my second monitor isn't detected on Ubuntu. It worked fine before. When i try using Windows 7, it is detected. I'm using HP Pavilion G4 1212tx AMD ATI Radeon.

Why isn't it detected? Is there a problem with my VGA card?

I have one speaker next to my computer which I use mostly as a headphone amplifier. On occasion I need to use it as a loudspeaker. Is it possible to quickly change the audio output from stereo to mono, either system-wide or as a plugin for a media player?
