Please describe your issue in as much detail as possible:

Describe what you expected should happen and what did happen. Please link any large code pastes as a Github Gist

Steam for Linux was running perfectly well on my gaming laptop in Kubuntu 24.04.

Then I installed a LinkedIn application called LinkedHelper.

In order to get the application working properly with LI's APIs, their tech support made me add some cron jobs:

@reboot sudo sysctl -w kernel.apparmor_restrict_unprivileged_unconfined=0
@reboot sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0

Ever since then, Steam won't launch. Nor will individual games from my menu bar.

I removed the cron jobs.

I uninstalled Linked-Helper via apt-get.

I rebooted my machine a few times.

I uninstalled and reinstalled Steam from my Discover package manager.

The Steam client still won't boot.

Steps for reproducing this issue:

Are you sure you were not hacked?

Apparmor is Linux security system, and disabling parts of it is not something a Linkedin tool or any tool should be doing.
Not sure what restrict_unprivileged options do, but if I were you I would start by enabling them back (assuming that was the default which I don't know if it was):

sudo sysctl -w kernel.apparmor_restrict_unprivileged_unconfined=1
sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=1

Its also possible that the person you talked to already got access to your computer and made more changes in it, at that point I would suggest a fresh install.

Nothing extracted yet.
