Comment 0 for bug 2024637

As of snapd 2.60, when installed as a snap, snapd includes its own vendored apparmor_parser and configuration. As such, it generates profiles using newer apparmor features than the system installed apparmor may support.

In LP: #1871148 apparmor was updated in focal+ to stop loading apparmor profiles generated by snapd as since snapd 2.44.3 it has shipped the snapd.apparmor.service unit which loads its apparmor profiles on boot.

apparmor in bionic and xenial should be updated to stop loading snapd generated apparmor profiles and instead leave this up to snapd.apparmor.service.
