After installing F44 on VM and open Gnome Software, I got stuck at this:
Then I tried to use pkcon refresh force command and it gave me an error:
david@localhost-live:~$ pkcon refresh force
Failed to contact PackageKit: Error calling StartServiceByName for org.freedesktop.PackageKit: Timeout was reached
david@localhost-live:~$
Then I tried to restart packagekit service, it gave me an error too:
david@localhost-live:~$ sudo systemctl restart packagekit.service
Job for packagekit.service failed because a timeout was exceeded.
See "systemctl status packagekit.service" and "journalctl -xeu packagekit.service" for details.

This issue didn’t happen on host machine, the host machine’s Gnome Software is normal.
