Installing in a virtual machine, the spinning worm doesn't spin.
The progress bar moves, the install works, but there was apparently
no point in the spinner at the left of the progress info.
The first thing the intro to gnome 42 tells me is to use the "Super"
key. There is no key labelled "Super". Some hint about alternate
names might help the newbies the intro is presumably designed
to help (experimentation revealed it was the Start key :-).
Shutting down the virtual machine hung for about two minutes waiting
for packagekit.service to stop.
