gdm-hw-accel.service: Two services allocated for the same bus name

[lucabelluccini]

Describe the bug
Prior to update 25430, I had no more the graphical login and desktop.
I updated to the version mentioned above and I can get to login but I get:

> dmesg
...
...

[    4.475535] systemd[1]: gdm-hw-accel.service: Two services allocated for the same bus name org.gnome.DisplayManager, refusing operation.

And I've got

This looks like a leftover from a swupd update, this was removed from a while now, (May 7 apparently: clearlinux-pkgs/gdm@68e0e80 ).

What's the output of running the following command?

$ sudo swupd verify --picky

Hello! Thank you for assisting on this.

I get:

Should I issue a swupd verify --fix --picky ?

--fix for sure will correct this

from swupd (1)

       verify
          Perform system software installation verification. The program will obtain all the manifests needed from version url and  content  url
          to establish whether the system software is correctly installed and not overwritten, modified, missing or otherwise incorrect (permis‐
          sions, etc.).

          After obtaining the proper resources, all files that are under control of the software update program are verified  according  to  the
          manifest data

          · -f, --fix
                Correct  any  issues found. This will overwrite incorrect file content, add missing files and do additional corrections, permis‐
                sions etc.

          · -Y, --picky
                List (without --fix) or remove (with --fix) files which should not exist. Only files listed in the manifests should exist.

so likely a # swupd verify --fix --picky should be performed.

Thank you @mrkz @fenrus75
Worked like a charm.
It solved the issue. The service was removed.
