title: "AppArmor issues"

description: "More information on why missing AppArmor marks the installation as unsupported."

## 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](/more-info/unsupported/os).
