Every other reboot I have no networking and a lot of "Unexpected error response from GetNameOwner()"

sender · 24 May 2020 15:43

Hi,

I'm quite puzzled by this one and I wonder if someone can give me a pointer on how to debug this.

It happens almost on 1 in 2 reboots. Boot seems fine until SDDM flickers (crashes). After that, it's possible to log in, only there is no networking at all (WLAN, Bluetooth, WWAN). Contents of the error logs right after login:

Was getting the exact same error and starting using this as a work around for now. Still looking into the error.

I edit the /etc/nsswitch.conf file and then was able to boot again in 7 seconds. Better than 1 min.

# Name Service Switch configuration file.
# See nsswitch.conf(5) for details.

## passwd: files mymachines systemd
## group: files mymachines systemd
shadow: files

publickey: files

hosts: files mymachines myhostname resolve [!UNAVAIL=return] dns
networks: files

protocols: files
services: files
ethers: files
rpc: files

netgroup: files

as you can see I edited out passwd and group with ## so I can easily remove when the bug gets fixed.

sender · 10 June 2020 09:00

What kernel are you using? I'm now testing with 5.7.0-3-MANJARO and no errors until now.

Whinery · 10 June 2020 12:35

I'm using Archlinux and it's happening to me on lts and the latest kernels. I'm not sure if it's dbus or systemd causing the error as both have been updated. Been on the road a lot lately so only had time to google the problem.

Termy · 6 July 2020 14:47

did you find anything yet?
I'm using your workaround, too and found out that it causes Polkit issues (kate can't use poltik anymore for example)

edit: it seems with dbus-broker the issue with boottime/nm is gone, but kate/polkit still persists

Whinery · 6 July 2020 15:51

Will try to boot normal later today, so far no issues at all but was able to enable passwd again. Only have group ## out.

Termy · 6 July 2020 20:08

interesting, i can confirm that only removing systemd from group solves the boot time issue - but sadly polkit/kate still won't work

Whinery · 7 July 2020 03:18

Tried without the group # out and the problem returns after the first boot. Just never had the time to look more into it and can't find any new post on the matter at this time.

sender · 7 July 2020 07:38

For what it's worth: I'm still on 5.7.0-3-MANJARO and didn't edit /etc/nsswitch.conf, and haven't seen the error since.

Termy · 9 July 2020 16:48

for todays update i reverted my system to a working state with timeshift (10.6.2020) and updated from there - unfortunately the issue came back, so definitely not a configuration issue.

sender · 9 July 2020 17:04

haven't seen the error since

I spoke too soon

Today I had a freeze (again): KDE lockscreen, mouse cursor works, no way to log in, restarting plasmashell and/or kwin does not work.

After a reboot via a tty I experienced this issue again. A reboot later: no issue.

Termy · 3 August 2020 08:53

good news, there is a better workaround than the nsswitch.conf thing that breaks polkit for me: disable org.cups.cupsd.service and use socket instead!

systemctl disable org.cups.cupsd.service
systemctl enable org.cups.cupsd.socket
