What to do to enable the Add/remove software to work properly? It freezes

Hi it’s me again.
So when I try to install the packages related to buildbot the Add/remove software application freezes.
What should I do to remediate the problem?

buildbot is in the repo, so what does sudo pacman -Syu buildbot say?

I have tried to install the linux driver “wired” and the error was in a build() function, so I’ve searched for all the apps that have [build] in their name and installed them, eventually. And eventually, it worked.

The issue that I had was, after the screensaver was activated and thus the system locked and the internet connection disconnected, when I tried to connect back, it did connect but the webpages wouldn’t load.
