Hi, I don't know what happened in Gnome Software, but it only worked one time.
The first time I ran it as a normal user, it didn't prompt me for the root
password and it couldn't access any information. So I ran it as root, and all
looked good. It was showing featured apps and all the tabs worked. I went to
the update tab and refreshed, and it said no updates. So I closed Gnome
Software and opened YaST to check if there were indeed no updates. The next
time I opened Gnome Software, it doesn't work. It only says "No application
data found". I restarted the entire system, and un-installed/re-installed
gnome-software with its depenencies, but it doesn't work.

Thanks for looking into this!
