sigh. How did I miss that? (don't answer!) You're correct. It's for
zoom meetings. On a few issues that I bring to this list, I wish I
could do a zoom meeting to deal with it. With one of this list's
authoritative experts on the other end, it would be faster, easier, and
more effective. Both microsoft and HP have tools for connecting to a
remote windows workstation; such a tool could also work. Does Fedora
have such a tool?
Gnome has built-in screen sharing, but you need a separate channel for
audio. It also doesn't work through NAT because that would require an
outside server.

Mostly agree. Let's put this aside for now, deal one two other upgrade
questions/issues, and then handle the too-nearly-full filesystem in a
separate thread. But I think ultimately, the junk ought to be properly
identified and cleaned out.
Personally, I don't think it's worth the effort to figure out what
little can be removed.
The first upgrade question/issue:
During the download phase, dnf displayed the following:
-----
Running transaction test The downloaded packages were saved in cache
until the next successful transaction. You can remove cached packages by
executing 'dnf clean packages'.
-----
and when re-doing the download, dnf displayed the following:
-----
Download complete! Use 'dnf system-upgrade reboot' to start the upgrade.
To remove cached metadata and transaction use 'dnf system-upgrade clean'
The downloaded packages were saved in cache until the next successful
transaction.
You can remove cached packages by executing 'dnf clean packages'.

My sense is that those two dnf commands are things the sys.admin. does
if something goes wrong and he has to back-track (or start over). Am I
correct, or should I do those? By the way, the dnf man page makes no
mention of a system-upgrade command.
The first one is specific to the system-upgrade plugin because it puts
the files in a different cache location than normal dnf. You would only
need that if you decide not to do the upgrade and want to get the space
back. Or very unlikely, in case something really went wrong and dnf
can't recover from some corrupted files.
The second one is just the standard bit that dnf always puts at the end
if you don't actually run the transaction (e.g. --downloadonly). The
same reasons as the other one.
