Public bug reported:
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.
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.
