AppArmor is a security tool that uses name-based mandatory access controls to restrict or confine the system access of “at risk” applications. AppArmor is not supported by Parallels Plesk Panel (Plesk). Sometimes AppArmor can interfere with Plesk installation or functionality.


Disable AppArmor using the following commands:

# /etc/init.d/apparmor stop
# /etc/init.d/apparmor teardown
# update-rc.d -f apparmor remove

Then restart the server.

Alternatively, you can try to remove the apparmor package with your package manager (run apt-get remove apparmor). Do not 'purge' apparmor if you think you might want to re-enable AppArmor at a later date.
