** Description changed: In the past weeks we experienced few systems coming up without started dbus-daemon after reboots due to updates. 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. - + January 19th there were updates for systemd (systemd:amd64 from + 245.4-4ubuntu3.3 undated to 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) + Loaded: loaded (/lib/systemd/system/dbus.service; static; vendor preset: enabled) + Active: inactive (dead) TriggeredBy: ● dbus.socket - Docs: man:dbus-daemon(1) + 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. + When rebooting the affected machine again, this does'nt occur again, and + the dbus-daemon is started and working again.
