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, set this to the Linux boot cmd: apparmor=1 security=apparmor and 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.
