Update instructions

After a standard system update you need to reboot your computer to make all the necessary changes. A new utility, called aa-remove-unknown, was added to assist with profiles that would have been previously unloaded when AppArmor was restarted or upgraded.

Learn more about how to get the fixes.

The problem can be corrected by updating your system to the following package versions:
