Okay, but what did the error message say? And what triggered it?
It's really hard to help diagnose a problem if you don't actually describe the problem - beyond it being "fascist".

The message was insufficient authorization as I reported. What triggered it was trying to actually install apps (instead of just selecting them) as I reported.
I reinstalled with today's rawhide. The keystroke beeping is gone. I was able to install apps.
