Public bug reported: From https://forum.snapcraft.io/t/snapd-doesnt-allow-notification- daemon-to-be-activatable/22912
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 https://github.com/mate- desktop/mate-notification-daemon/pull/201 ProblemType: Bug DistroRelease: Ubuntu 21.10 Package: mate-notification-daemon 1.26.0-0ubuntu1 ProcVersionSignature: Ubuntu 5.13.0-16.16-generic 5.13.13 Uname: Linux 5.13.0-16-generic x86_64 ApportVersion: 2.20.11-0ubuntu69 Architecture: amd64 CasperMD5CheckResult: pass CurrentDesktop: MATE Date: Mon Sep 27 20:05:15 2021 InstallationDate: Installed on 2021-09-21 (6 days ago) InstallationMedia: Ubuntu-MATE 21.10 "Impish Indri" - Beta amd64 (20210921) SourcePackage: mate-notification-daemon UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: mate-notification-daemon (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug impish -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1945234 Title: Snapped apps are unable to trigger mate-notification-daemon To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mate-notification-daemon/+bug/1945234/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
