After the systemd-234 upgrade, systemd-networkd ("enabled" in multi-user.target.wants) would fail during system startup: systemd-networkd[132]: Could not connect to bus: Connection refused leading to the service failing with "Failed with result 'protocol'" This was also on a completely empty /etc/systemd/system directory, enabling only systemd-networkd. It works fine if "dbus.service" is added to "After=" in systemd-networkd.service.
That does not sound right. Please report the issue upstream.
(In reply to Mike Gilbert from comment #1) > That does not sound right. Please report the issue upstream. I already found it on the bug tracker - See URL (https://github.com/systemd/systemd/issues/6435)
Does adding "After=dbus.socket" also resolve the issue?
To clarify, please replace After=dbus.service with After=dbus.socket and re-test.
Yes, After=dbus.socket is sufficient too!
The upstream issue you found was unrelated to this bug.
Reported a new issue upstream.
Could someone test the changes from this pull request? https://github.com/systemd/systemd/pull/6659
Thanks for reporting upstream! I can confirm that the fix in pull request https://github.com/systemd/systemd/pull/6659 works (lets systemd-networkd start rather than fail on my systems). As I see, the fix extends an internal retry loop to also include the error occurring when dbus is not yet up. I cannot imagine that this solution is really what the systemd authors intend, as it hides the information on the condition for which a service is waiting from the system. As I understand it, it would be cleaner to add dbus.socket as a dependency. Then this dependency is explicit and systemd-networkd may simply fail if it isn't met, just as before. I'll post the same on the pull request now.
(In reply to Bernd Feige from comment #9) Well my musings are obsolete - Poettering just merged the pull request, so this appears to adhere to policy...
Should be resolved in 235.
I am still facing this issue on one machine with sys-apps/systemd-246-r1 But it does also not seem to wait after connecting to dbus failed and rapidly tries 5 times and ultimately fails: -- Reboot -- Okt 11 23:06:10 heisenberg systemd[1]: Starting Network Service...
