Bug Description

Hi,

today while inspecting logs with journalctl, I noticed error messages during shutdown (see below). The problem is that some (but not all) snaps fail to unmount. For instance:

sept. 15 11:20:01 vougeot systemd[1]: snap-hello\x2dworld-27.mount: Mount process exited, code=exited status=32
sept. 15 11:20:01 vougeot systemd[1]: Failed unmounting Mount unit for hello-world.
