I'm coming with bad news. Today both me and Michael have individually retested both snaps you provided (20211102 and 20211105), and the bug happened with both of them. It's possible that yesterday Michael accidentally used QEMU for his tests, without realizing (and in QEMU it seems that this bug is not reproducible).
Here are the spread logs (plus "journalctl -xe") obtained in the 21211105 snap: https://paste.ubuntu.com/p/CnnyXNC2Tt/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1949089 Title: systemd randomly fails to activate mount units in Ubuntu Core 18 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1949089/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
