AppArmor issues

The issue

AppArmor is how the Supervisor does handling all the security around add-ons, without this, the Supervisor is missing important security mechanics to protect your system and data within it.

The solution

If the AppArmor is not enabled on your host, add this to the Linux kernel boot parameters: apparmor=1 security=apparmor and then reboot your operating system.

As a last resort, you might need to reinstall the host running the Supervisor with one of the supported operating systems, see instructions here.
