(In reply to Cristiano Guadagnino from comment #40)
> Thank you @ChristianBoltz, with your fixed package my snaps are working now.

sorry, you would have needed to use

  apparmor_parser -rT /var/lib/snapd/apparmor/profiles/

the -T will cause apparmor to skip reading from the cache, forcing it to recompile the profiles. Since the neither the profile files nor the includes files were changed, apparmor will think the already compiled policy in the cache is still valid and load that.
