Hi,
Unfortunately, I run the following line thinking it would remove unused permissions. But apparently, I was far from the truth.
sudo aa-remove-unknown
After that, programs installed with snap stoped working because of the famous
snap-confine has elevated permissions and is not confined but should be. Refusing to continue to avoid permission escalation attacks
I tried most of the advice linked to restarting AppArmor, without success.
I tried to reinstal snapd hoping it will add back correct profile, but does not work
Here is the list of profiles removed:
