Step to reproduce:

- Install lxc package
- I see the following error message on AppArmor.

I guess the cause would be that lxc package doesn't include
config/apparmor/abstractions/start-container

https://github.com/lxc/lxc/blob/master/config/apparmor/abstractions/start-container.in

$ sudo systemctl status apparmor.service
