It's not like I was going "off book" and trying to install my own network management app, or something like that, where, if I messed it up, then, yes, it's on me to go through the packages and find "the problem child," etc.</div><div><br></div><div>I'm essentially an "end user" . . . looking for basic function of the GUI, and I run apt and follow the prompts to maintain a system.

I have Lu 21.04 installed on my desktop as well, and looks like tomorrow it will be up for the daily driver, I'll run apt on it and see what happens with it, if anything shows up that might point to a problem . . . I can test wifi on it as well.
