Qubes Global Config doesn't start

How to file a helpful issue

Qubes OS release

4.2

Brief summary

qubes-global-config doesn't show up. I did no changes to the system I'm aware of since the last time it worked, but there had been updates. It may be a transient bug, I'd be happy to diagnose but don't know how / what logs are interesting.

Steps to reproduce

Opening global config from the application-finder or application-menue or running qubes-global-config in dom0 should open the global config editor.

Expected behavior

Qubes Global Config Manager appears.

Actual behavior

The tiny loading-window appears for a moment and vanishes again, nothing happens.

qubes-global-config has no verbose-option, so I don't know how to supply more info.

Is there also no error or otherwise message in dom0 terminal when you run it from there? There really should be :/

[GammaSQ]

No, nothing. even echo $? is 0 ...

[GammaSQ]

Aha! there were two processes of the same name still running:

[user@dom0 ~]$ ps -A |grep global
   4309 ?        00:00:01 qubes-global-co
  64520 ?        00:00:00 qubes-global-co <defunct>
[user@dom0 ~]$ sudo kill 64520
[user@dom0 ~]$ qubes-global-config
[user@dom0 ~]$ sudo kill 4309
[user@dom0 ~]$ qubes-global-config

strangely enough, killing the defunct process didn't help.

[marmarta]

Oh no, this sounds like Gtk being Gtk... Did killing both of them help? Maybe the config was open somewhere on some other desktop?

[GammaSQ]

yes, sry, should have clarified: killing both allows starting the global config again. No issue from cli, application-finder, or other.

Background: not visually. I initially checked whether the window was already open and therefore couldn't pop into my view.
