Thanks ddstreet, I agree 918e6f1c0151429f5095355f4f3f74f16e79724a could be related as well, but unfortunately that commit produced quite some fall-out.
Nevertheless, I've prepared a new systemd build in my PPA and the "core18_20211118_amd64.snap" at https://people.ubuntu.com/~slyon/uc18/ cherry-picking the changes from https://github.com/systemd/systemd/pull/8675 (incl. 918e6f1c) As I said, there are quite some other PRs related to this, in order to clean-up after it https://github.com/systemd/systemd/pull/8798 https://github.com/systemd/systemd/pull/9200 https://github.com/systemd/systemd/pull/9229 https://github.com/systemd/systemd/pull/9366 In total that should be approx. 1000 changed LOC... So I'm not sure how suitable this is for SRU. But let's first give this newest build a try and check if the initial commit/PR changes anything wrt to our core problem here, if so we can into the details of those backports (and hopefully skip manny commits of those). -- 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
