This affects dbus, but the last change that could probably have caused this was in systemd.

The first occurrence happens on January 21th 2021, since this time we were experiencing 0 up to 2 machines with this issue on each reboot cycle affecting all (approx 20) Ubuntu 20.4 (Focal Fossa) LTS machines. On January 21th the machines were rebooted due to a kernel update. On January 19th there were updates for systemd (systemd:amd64 245.4-4ubuntu3.4) installed. The Symptoms seem to be: ``` root@es1:~# systemctl status dbus ● dbus.service - D-Bus System Message Bus Loaded: loaded (/lib/systemd/system/dbus.service; static; vendor preset: enabled) Active: inactive (dead) TriggeredBy: ● dbus.socket Docs: man:dbus-daemon(1) ``` There is no `dbus-daemon` process running any more after reboot. The messages in /var/log/syslog: ``` Feb 24 09:21:52 runner1 kernel: [ 11.005391] systemd[1]: sockets.target: Found ordering cycle on dbus.socket/start [...] Feb 24 09:21:52 runner1 kernel: [ 11.012386] systemd[1]: sockets.target: Job dbus.socket/start deleted to break ordering cycle starting with sockets.target/start ``` Jounalctl output ends with the dbus-Shutdown before reboot, and it is not updated any more. When rebooting the affected machine again, this does'nt occur again, and the dbus-daemon is started and working again. We experienced this on 4 rather different machines on 6 reboot cycles across all Ubuntu 20.4 (Focal Fossa) LTS machines till now. We are not experiencing this on other LTS releases than 20.4.
