This is a follow-up to my post last night about the new Athenaeum game manager.    I say "new" only because
it is a fairly recent project.

I ran an update via terminal in both dnf and flatpak, and the Athenaeum-installed-apps did not update.

But Gnome Software said all the twenty-four games ( that I had installed last night ) had updates available
( most in the 694.8 MB range ).     So I clicked on "Update All" with my slow but reliable ethernet
 connection of 40 Mbps.

After about 20 minutes, nothing has happened.     The boxes read "Installing" in light grey letters.

So is there a way to do this from terminal ?    They are just regular flatpaks.   Right ??
