Just upgraded to 20.04. At first the software center was working fine. I could scroll down and look at the categories. I could click on the installed tab and see the installed apps. A few hours after later the installed tab is just blank. Today, I can't scroll down to the categories. Is this just a bug that will get fixed soon or should I reinstall it? If so, how do I reinstall it?
Restart your PC!
Same problem after fresh install of Ubuntu 20.04, there are no categories in the software center.
What I did: opened the terminal (Ctrl+Alt+t), then
sudo apt install --reinstall gnome-software
I tried to open software center, still the same. Then, restarted my machine and voilà:
I don't know if it is worth mention but I think in the beta version software center was fine. I don't remember having problems.
