Upgrade issue — Bus owner changed, aborting

Hi, there.

I’m using Fedora Silverblue 30. And I’m having trouble upgrading.

I’m getting this error: Bus owner changed, aborting. on running rpm-ostree upgrade.

I also checked this discussion forum — Bus owner changed, aborting when trying to upgrade — didn’t get it completely and ain’t there a solution, too.

Appreciate your help guys.

Great day.
