We discussed on IRC that this is because *no* systemd units are being activated; the user session is not being run under systemd. This is a regression vs. unity, and should be considered a bug in the desktop session as a whole.
Reassigning this to gnome-session, which seems like the correct starting point. ** Package changed: update-notifier (Ubuntu) => gnome-session (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-session in Ubuntu. https://bugs.launchpad.net/bugs/1743366 Title: Systemd .path units are not working properly in Bionic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/1743366/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
