gnome-control-center crashes when try to open it

[adin]

gnome-control center crashes when trying to open it. Tested as following

$ gnome-control-center --verbose
**
cc-object-storage:ERROR:../shell/cc-object-storage.c:167:cc_object_storage_add_object: assertion failed: (G_IS_OBJECT (object))
Bail out! cc-object-storage:ERROR:../shell/cc-object-storage.c:167:cc_object_storage_add_object: assertion failed: (G_IS_OBJECT (object))
Aborted (core dumped)

When trying to open it through the graphical interface it dies silently. A message of error would help too.

Strangely, purging nvidia drivers seems to fix the issue (following advice from https://askubuntu.com/a/1183137/44054). However, I had a different error as noted in the original bug description.

However, now I can't have nvidia working with the settings.

[adin (adin-rivera)]

Further information. After updating the packages the error returned (nvidia is still uninstalled).

$ gnome-control-center --verbose

The kernel is the same.

Thank you for your bug report

Can you provide the output of those commands?

$ dpkg -l | grep gnome-control-center
$ which gnome-control-center
$ ldd -r $(which gnome-control-center)

[adin (adin-rivera)]

Sure. The output is

Thanks, in fact looking at the error it's similar to https://gitlab.gnome.org/GNOME/gnome-control-center/issues/342

Did you try to replace network-manager by another component or having it not working?
What's the output of
$ systemctl status NetworkManager

[adin (adin-rivera)]

The output of the command you asked for is

As the other thread mentions, it seems that it has to do with the NetworkManager. Since mine was already running (as I understood from the output above), I restarted it with

$systemctl restart NetworkManager

and the settings are working again. But the outputs of the status seems the same to me. See, after restart

$ systemctl status NetworkManager
