Launching Snap Package on Solus 4.2 Fails: cannot query current apparmor profile: Invalid argument

Case: Snap package (keepassxc and keepassx-elopio) refuses to launch after a successful install. Running package through the terminal throws error: cannot query current apparmor profile: Invalid argument.

Solution

Reinstall snapd, force-run system triggers and reboot.

sudo eopkg rm snapd && sudo eopkg it --reinstall snapd && sudo usysconf run -f && reboot
