Snapped apps are unable to trigger mate-notification-daemon

Bug Description


Snapped applications are unable to trigger the mate-notification-daemon due to the service file not specifying an assumed apparmor label so apparmor does not know that it is unconfined and thus may receive the dbus calls. Snapd specifies in the apparmor policy that the label must be "unconfined".

I've filed an upstream PR to fix this at

This likely affects all of Impish, Hirsute, Focal, Bionic, and Xenial but I haven't validated the earlier releases.

Its not clear to me where this is Fix Committed and I don't want to just upload this and undue any work Martin has on going, subsequently I'm going to unsubscribe the Ubuntu Sponsors team. However, once this has been fixed in jammy feel free to prepare some debdiffs and test cases for Stable Releases.
