Since 08.06.2024 update of Chromium (snap) on my Xubuntu 22.04 LTS, Chromium has stopped working. Also don't work Brave Browser (also snap), Video Downloader and some another program.

How to solve this problem?
 


G'day codelenovo, Welcome to Linux.org

I know zero re snaps.

But a reasonable conclusion would be that the drama is entirely snap related. Have you had these problems before this?

Was there a kernel upgrade immediately prior to this happening ? ....anything that may have changed something, somewhere ?....

Script to get rid of Snap - Kubuntu Forums

Purpose of this script This is a little helper script for Kubuntu™ users who want to get rid of and block Snap entirely (like Linux Mint and TUXEDO OS do), including the Firefox Snap in 22.04 LTS & later and e.g. the Thunderbird and Firmware Updater Snaps in 24.04 LTS. It has been tested many...

fwiw, I have zero problems with Flatpaks.


Others here may have a solution to your immediate problem
 
There could be several things causing this

When you updated the snapd package did you use sudo? I see this - "cannot open directory "/usr/local/share": permission denied"

This may be linked to AppArmor, it secures the snaps. In your Home directory in Ubuntu check to see if the default folders (images, music, videos, etc… ) have a symlink with the same name pointing to other drives or somewhere else. This could be causing a security issue with AppArmor. If there, try to remove the symlinks and put back the folders, reboot and the snap should now launch. You can apply that solution to other snaps.

You can try re-installation with
snap remove snap-store

followed by
snap install snap-store

No. Symlinks are ok. I DON'T change anything more weeks.

And another people have the same problem (for example, I read about this on AskUbuntu, but without solving).

P.S. I use Xubuntu 22.04 LTS, not Ubuntu.

It's bad form etiquette to post the same question in different places. For this problem it's probably best to report a bug to Ubuntu or to the Snap package developer.
 
It's impolite and extra work for volunteers when you ask your question at multiple places. We have no idea what you've covered elsewhere, what they've suggested, what you've done to test, etc...

You're wasting our time. Time is a limited asset. Please don't do that.
