I am using Ubuntu for many years now and feel relatively safe that I could recover from weirder mistakes/problems as well (with the help of this forum e.g.). However, over the time some relatives and friends have also begun using Ubuntu, initially with my help. Can I just tell them to run

sudo apt update && sudo apt upgrade && sudo apt autoremove

once a week? (potentially with the -y flags)

What are the problems that could come up? As far as I understand autoremove always keeps a "backup" kernel as well. These are regular users, they are doing nothing special like managing a server, it's only their private machines.

In my Qt app, I display the svg icon in the about page.

While the icon is displayed correctly, I get the following error message in terminal:

qt.svg: /usr/share/icons/hicolor/scalable/apps/io.github.archisman_panigrahi.QuickBib.svg:150:32: Could not add child element to parent element because the types are incorrect. 

How to fix this error?

I'm talking about this interface.

Wired connections rule, in my world.
And I had my "old" laptop connected to amp and mixer , all working good with x11vnc. All my laptops then on 24.04.

Curious about new upgrades, I used to alfa and beta test, I upgraded to 25.10 and found that wayland does not play by the same rules. Earlier setup is not working.
Immediately I remembered I had done same before, different upgrades on server/client leading to workaround, but then I could fix it.

My main lap is Ubuntu 24.04.3 LTS, my server is 25.10

How do I get a remote connection, mostly streaming, to work again?
Do I have to upgrade my main from LTS?
Superhappy if I could get help about how to get this working again :)

Does Ubuntu Ubuntu 24.04.3 LTS support Armenian language?

I cannot add Armenian language to keyboard.

I deployed a fresh virtual machine using the Ubuntu 24.04 Desktop ISO.

The installation completed successfully, and the VM boots without any visible errors. However, when I try to access the GUI through the web console, the screen shows only a loading screen, as shown in the attached screenshot.

Even though the GUI does not load, the VM appears to be running normally — pinging the VM’s IP address is successful.

What I’ve tried:

• Rebooting the VM

• Reconnecting to the web console

• Increasing the video memory from the default 8 MB to 12 MB

Has anyone encountered this issue with Ubuntu 24.04 Desktop in a virtualized environment?

Are there any known display or graphics-related issues, or recommended configurations to resolve this?

I'm looking for a software recommendation for a desktop environment for a Samsung touchscreen device. Samsung calls it a tablet, but it also has a detachable keyboard that permits it to be used as a laptop. The most important factor for me is to have a good user experience while using the touchscreen.

I am attempting to install and run cmake 4.2. Several warnings repeatedly appear, some of which I think I could fix once I complete the installation. How can I suppress these messages? This would allow me to better locate any error messages.

Please help, I'm new to Linux, trying to escape from Microsoft Windows:

I have Ubuntu installed on a Raspberry Pi 5, this was done via the Raspberry Pi Imager and selecting Ubuntu Desktop to image its SD card.

It booted and updated OK. Overall, running well until I ran into the power management problem.

Just a few of my USB devices would not recover though. That is good but I have no GUI option to stop it over when back to wake state.

There is no GUI option to disable it even though it is not a portable device.

I found also that my PI 5 does not use GRUB so I could not use any of those posted solutions.

So, how can I get USB auto-suspend turned off?

Today, I installed Ubuntu on my desktop PC. It works well, but when I reboot, it can't find the boot files, so I have to go into the BIOS boot menu and select my SSD every time I want to start my system.

I added some entries to my ~/.XCompose file and they work fine.

Except, those with <?>, <+>, and <*> seem to be ignored (perhaps others too).

Significantly, when editing it in vim, rather than the usual red colour, those three sequences are displayed in white:

I couldn't find any documentation saying that these characters are disallowed, or how one should enter them.

I am not able to get scanning working on my HP Smart Tank 523 printer. Printing works fine, but scanning always fails with a SANE error (logs screenshot attached). I also think it is a known problem on ARM devices where printing works fine but scanning fails.

I have tried both the package version (3.23.10) and manually installing other versions of HPLIP (3.25.6), (3.25.8) on Ubuntu Server 24.04. Does anyone here have a fix?

I created a software called QuickBib, and I also made a snap package. Here is the yml file for snap. It is a python app using pyqt6.

The snap package gets a theme that looks like Windows 95. The APT package, of course, uses the correct system theme. Even the flatpak adheres to the system theme.

How to fix the theme in the snap package of my app?

I am using Kubuntu 24.04.

I recently installed Ubuntu 24.03.3 LTS on a new bought Lenovo IdeaPad 5 2-in-1 14IAL10, alongside Windows 11. Everything worked fine (except the Realtek sound card, but that's another issue) until after two days the bootloader didn't show up anymore. It's not listed in the bios either. The only option there is the Windows bootloader. I can still log in the Windows 11 partition, but not anymore into Ubuntu. With an Ubuntu live edition I downloaded "Boot repair" and got the following report:

Does anybody have an idea what to do? Thanks for input on the issue.

I just noticed a new kernel version is available via apt-cache search linux-image (6.14.x)

From what I understand, this is the latest LTS version of the kernel, and is suppored/shipped with the latest Ubuntu 24.04.3 (my system was upgraded from 24.04.1 over time).

Just curious before I upgrade if there's anything I should be wary of when upgrading/if anyone in a similar situation upgraded and had success/issues when updating the kernel?

This should almost certainly be on Meta. Apologies, I had to create a new account to submit this question because of the issues below. Can a moderator please move this?

Stack Exchange appears to have automatically logged me out of Ask Ubuntu. When I attempt to log in, using Launchpad, it creates a new token on Launchpad and claims that token:

List of authorized tokens showing Ask Ubuntu as the application in the "Claimed token" section:

I also got an email from Launchpad confirming the token creation:

Email showing "A new OAuth token consumer was enabled in Launchpad.":

(I tried going to irc.libera.chat but the website seems to time out. I haven't tried (re)installing an IRC client yet.)

However it always returns me to the same page that says "Launchpad Login failed. Please try logging in again.":

I have tried:

1. Disabling all ad blockers
2. Clearing the cache
3. Accepting all cookies on both sites
4. Changing the token access all the way up to "Change private data"
5. Attempting to log in through Incognito mode
6. Deleting all other Launchpad Tokens (both claimed and unclaimed)
7. Using Firefox (instead of Chrome)
8. Waiting a couple of days

This is, of course, all on Ubuntu. I haven't tried from Windows (puke) or MacOS (lol).

Is the Launchpad login broken?

After upgrading from 21.10 to 22.04, Apache server does not start anymore:

The available librarie is:

$ ls -l /usr/lib/apache2/modules/libphp*
-rw-r--r-- 1 root root 5354272 apr  7 19:46 /usr/lib/apache2/modules/libphp8.1.so

Here the content of the offending mods:

$ cat /etc/apache2/mods-enabled/php8.0.load
# Conflicts: php5
# Depends: mpm_prefork
LoadModule php_module /usr/lib/apache2/modules/libphp8.0.so

Changing it to libphp8.1.so leads to apache2 service restarts correctly.

Why it didn't update this file? What should I do to avoid this manually hacking?

I'm trying to port a project that uses Clang's LibTooling library from Arch to Ubuntu/Debian. I have installed the clang-10, llvm-10 and libclang-10-dev packages. The latter installs the necessary headers to /usr/lib/llvm-10/include/clang/ (i.e. usr/lib/llvm-10/include/clang/Tooling/Tooling.h). However, trying to link a program that uses these headers results in various linking errors such as:

undefined reference to `clang::ast_matchers::internal::DynTypedMatcher::matches(clang::ast_type_traits::DynTypedNode const&, clang::ast_matchers::internal::ASTMatchFinder*, clang::ast_matchers::internal::BoundNodesTreeBuilder*) const'

Under Arch I can resolve this with -lclang-cpp but no such library exists under Ubuntu. Several posts on StackOverflow recommend linking to various other libraries, so I have als tried:

-lclangFrontendTool -lclangFrontend -lclangDriver -lclangSerialization -lclangCodeGen -lclangParse -lclangSema -lclangStaticAnalyzerFrontend -lclangStaticAnalyzerCheckers -lclangStaticAnalyzerCore -lclangAnalysis -lclangARCMigrate -lclangRewriteFrontend -lclangEdit -lclangAST -lclangLex -lclangBasic

But that does not work either. Are the libclang-*-dev packages incomplete/broken? Am I missing yet another package? Or am I just linking against the wrong libraries?

This is the error I get when I boot from the installation media:

Please help me with this.

My wife's OSX laptop won't boot. I've pulled the drive out and plugged it into a USB adapter and can see it from my Ubuntu laptop.

When I plug it and run gdisk I get the following output:

What's the recommended course of action at this point?

And I should point out that the drive is a Samsung 840 Evo. I think I need to upgrade the firmware as I hear there was a bug. Could the corruption be related?

When I run snap list --all command it shows all the installed versions of snap packages.

Now there are so many disabled packages there which are no longer used. So I want to remove those packages. Here the command is snap remove gnome-3-26-1604 --revision=62 . Now I have to do it for all the revisions and for all the packages one by one. Is there any command which will remove the disabled or unused snap packages with single line of command?

Thanks in advance...

I'm pretty new to using Icecast. We are streaming MP3s from a Linux box with Icecast, but we need to move to AAC. How can I make Icecast stream AAC files?

I'm confused, VPN client worked flawlessly on my virtual machine and today when I tried it failed to connect to L2TP VPN server... This is the log from my client VM, can someone help? I changed nothing (on purpose) and I do not understand why suddenly peer does not want to authenticate and was that expected in the past or its a new thing? My tablet still manage to connect as before.

I have setup disk encryption with LUKS and configure it to auto mount when the system boots up. So now as it supposed, it prompts me a passphrase when the system boots up. If i enter the correct passphrase it continuous the system.

So in some cases I want to escape from typing my passphrase. Is there a way to do that?

I want to check the particular process in already running or not.

I refereed this Q&A.

But I didn't get any specific solution. Following is the example that I tried: I have created abc.sh file and run this script on background, like sh abc.sh &.

Now this file is running on background and I fire the ps aux | grep "abc" command.

Following is the output of this command:

prakash     3594  0.0  0.0   4388   820 pts/0    S+   16:44   0:00 grep --color=auto abc

After that I stop the abc.sh running script and fire the same command ps aux | grep "abc" command.

But I am getting same output like:

prakash     3594  0.0  0.0   4388   820 pts/0    S+   16:44   0:00 grep --color=auto abc

Is there any other way to find the process is running or not?

When I attempt to boot into Ubuntu 14, I'm able to get all the way into the GUI w/o issue.. but once i'm there, the background is corrupted (black/white stripe/block images) as is anything "inside" a window (the window chrome is fine however).

I CAN see the navigation bar and menu bars, but any dropdown windows are also corrupted. It doesn't matter if I'm booting up to "try" Ubuntu 14, or install it. Complete power-down (vs reboot from windows 8) doesn't seem to make any difference either.

System specs:

• MSI Mainboard, Z77 chipset (onboard Intel gfx disabled in BIOS)
• Core I5-3750K (stock clock), 16GB RAM
• *2x MSI TwinFrozr 7870's (AMD Radeon HD7870's)
• 3x Monitors - 2x ASUS VS239's, 1x Lenovo L2321 (rotated 90 degrees).
• 320GB Samsung SSD
• 2x WD 1TB HDD

*The video cards are NOT in CrossFire mode (bridge is not attached).. actually, there's nothing connected to the second card at all at the moment.

I would attach screenshots for reference.. but I don't have a high enough reputation to do so... You can find them here: corrupted screen images

I'd appreciate any pointers y'all might have. Thanks!

There are two places I go when I want to download Ubuntu installer images: cdimage.ubuntu.com and releases.ubuntu.com.

Both of these appear equally official: they are both subdomains of ubuntu.com, and the main Ubuntu website makes references to both for its download links. (http://www.ubuntu.com/download/alternative-downloads uses the former for its 'Network installer' download links, and the latter for its 'BitTorrent' download links, for example.)

If I visit http://releases.ubuntu.com/ and follow links for the current Ubuntu release, I reach a page that lists numerous links to desktop and server installer images. Likewise, if I visit http://cdimage.ubuntu.com/ and follow links in a similar manner, I get to another very similar page that also gives numerous links to desktop and server installer images. At the moment, these pages are:

• http://releases.ubuntu.com/trusty/
• http://cdimage.ubuntu.com/releases/trusty/release/

(Following '14.04' links instead of 'trusty' leads to pages identical to the above, aside from their URLs.)

The language used on those two pages suggests that each page lists all of the available image files. For example, they each say "A full list of available files, including BitTorrent files, can be found below", and they each provide a wide variety of link types (.iso, .torrent, .metalink etc).

Neither page makes any reference to the other page's existence, and for a long time I thought that these were simply two different URLs serving essentially the same list of installer images.

Right?

Now that I look more closely I see that, despite appearances, the actual lists of files are almost entirely different. For the Trusty release, releases serves i386 and amd64 images, whilst the cdimage site serves PowerPC and Mac-friendly images. Even going back to the Precise release, when the architectures overlapped more, there are still installer images on each page that are not available from the other.

I've searched for explanations as to why the two sites are so disjoint, but have so far found none.

I assume that releases.ubuntu.com is intended to hold the more common installer images, whilst cdimage.ubuntu.com is intended to be a more comprehensive archive, given that it also hosts installers for the various spins such as Lubuntu, Xubuntu, etc.

However, this still doesn't explain some things:

• Why is there no single page I can go to and see all available images? For example, if releases.ubuntu.com is reserved for the more popular images, why are these not also included in the (more comprehensive) list at cdimage.ubuntu.com?

• If there's a good reason for keeping them separate, then why does neither page acknowledge the other as a complementary source of installer images?

• Is there any historical reason for this split?

If anyone has any behind-the-scenes insight into this, I'd be interested to hear how things ended up this way.

I want to share the wireless Internet connection on my desktop with my old laptop, through ethernet.

I have ticked the option "Make available to others" on both connections, on my desktop, but my laptop doesn't connect. Am I doing something wrong or is it a bug?

Before installing a new OS I tried to backup my Thunderbird by copying the .thunderbird directory.

To be on the safe side I tried to emulate the restore procedure on another machine. I copied the .thunderbird directory to it and set up a symlink from /home/username/.thunderbird to this backup directory.

Thunderbird starts correctly, it shows plugins, calendar, address book, all news feeds and all mail accounts.

But for POP accounts it shows only the Inbox folder (which is empty) and the Trash folder. All the other folders are missing (Archives, Drafts, Sent).

What I have tried so far and it did not help:

• click 'Repair folder' from the menu folder;
• Delete .msf files to force Thunderbird to rebuild index;
• Delete Panacea.dat;
• start Thunderbird with -profilemanager to choose the particular profile directory;
• all tips from the official documentation.

It seems like Thunderbird successfully restores all the information from the backup, except the folders and messages for POP mail accounts.

Any ideas regarding such a strange behavior of Thunderbird?

I'd like to scan a good amount of papers I have lying around, with the least possible hassle. I would like to convert them to images using Simple Scan, then convert them to text using OCR. Is there a good OCR app with a GUI that will give me good results at the push of a button?
