I found these two bug tickets that could be relevant: https://github.com/home-assistant/operating-system/issues/896
https://github.com/systemd/systemd/issues/8683 I should also add that this seems to happen on the majority of boots for me, but not every boot. So there is some amount of non-determinism involved. I'm not familiar with what service / tool / part of kernel does what in the boot of an Ubuntu 20.04 system, but I might read up on what systemd- time-wait-sync.service waits for to see if I can figure out why that does not happen. Anyway, thanks for helping me debug this issue! ** Bug watch added: github.com/home-assistant/operating-system/issues #896 https://github.com/home-assistant/operating-system/issues/896 ** Bug watch added: github.com/systemd/systemd/issues #8683 https://github.com/systemd/systemd/issues/8683 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1937238 Title: systemd-time-wait-sync.service stuck in "activating" state after boot, blocks timers from starting Status in systemd package in Ubuntu: Incomplete Bug description: When I start my server running Ubuntu 20.04 the systemd-time-wait- sync.service is stuck in "activating" state. I noticed this because none of the systemd timer units triggered, because all the timers depend on systemd-time-wait-sync.service. Running "systemctl restart systemd-time-wait-sync.service" manually works around the problem.
