Run the following on the host: ls -l /etc/os-release /usr/lib/os-release and paste the output.

>  ls -l /etc/os-release /usr/lib/os-release
lrwxrwxrwx 1 root root 21 Feb 24 15:32 /etc/os-release -> ../usr/lib/os-release
lrwxrwxrwx 1 root root 26 Mar 19 10:01 /usr/lib/os-release -> ../share/tuxedo/os-release

Well that won’t work then. os-release is supposed to be a file under /usr/lib/os-release and /etc/os-release is a symlink to that file. Since the locations are known and fixed sandbox allows reading both. /usr/share/tuxedo/os-release is unexpected and accessing it won’t be possible within the sandbox.

Why zoom cares about the content of os-release is another question though that I do not know an answer to.

6

Zoom uses that info (falsely) to determine if the distro runs wayland, so it can take a different code path for screen sharing… (it is quite a bad implementation, but well, it is closed source, not much i can do about it on the packaging side)

7

Any suggestions on a solution for my issue?

8

Not recommended, but change the /usr/lib/os-release to /usr/lib/os-release.bak and copy the /usr/share/tuxedo/os-release to /usr/lib/os-release, thus it’ll become a real file

9

And maybe file a bug for the maintainers to implement the fix in the distro.

I think apparmor should allow to read files where the symlink of it is allowed

11

LOL they’ll just say to use the Flatpak version :smiley:

12

Heh, this is funny, given the flatpak version is actually a re-pack of my snap but with all confinement and most security bits dropped …

(Unless that recently changed)

seems like they won’t fix it

one of the main features of TUXEDO OS is to not support Snap at all.

Oh my…

one of the main features of TUXEDO OS is to not support Snap at all. Thanks for noticing the issue with the release file, we will look into it.

Quick damage control, eh?

I get why they removed Snap by default, but I’m glad they decided not to be overly hostile about it.

I willingly unblocked mine :slight_smile:
