I think this is related to https://github.com/systemd/systemd/issues/6680, specifically this comment:
"hmm, so OnUnitActiveSec= operates relative to a unit becoming active, but Type=oneshot service units actually never become active, unless you combine them with RemainAfterExit=, hence the confusion... Type=oneshot units after all do stuff during their start-up and when that's complete they go down again, they never stay up continiously... Hence, combining Type=oneshot with OnUnitActiveSec= can't really work... This is a big underdocumented though" Which seems relevant, since: $ cat /lib/systemd/system/motd-news.service [Unit] Description=Message of the Day After=network-online.target Documentation=man:update-motd(8) [Service] Type=oneshot ExecStart=/etc/update-motd.d/50-motd-news --force -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1829968 Title: motd [on at least some instances] does not auto-update daily To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/base-files/+bug/1829968/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
