[GNC] Install of GNC fails on Flatpak

[jeffrey black]

I'm having to do this via my cell phone so please excuse typos.

I had a complete network failure when a surge suppressor decided to explode in my face. Destroyed my server, multiple drives, printer, and my laptop. Other computers were not affected but did not have access to my GNC books.

Now that I have a new server and laptop I am trying to get my network back up and running.  Every time I try to install GNC on the server via snap I keep running into:

"Unable to install "org.gnome.Platform": Refspec 'flathub:runtime/org.gnome.Platform/x86_64/44' not found.

I'm running Ubuntu 22.04LTS.

I was running the latest flatpak version prior to this disaster.  The default Ubuntu version is way too far behind since I occasionally have to run GNC under the current WindDoze 10 version.
