(solution found) transitioning Boinc from APt to Flatpak version on Ubuntu 22 LTS without project data loss

Our client is behind the latest stable branch but perfectly usable in its capabilities. We basically start with what was known as the All-in-One package based on the original Berkeley installer.

We then add onto it with our custom team configurations.  But that client is limited to team members only.  We fixed some of the glaring client limitations that give the client more control over how it interacts with projects.

The AIO is available from the old Lunatics website where the old Seti custom app developers hung out.

It is nothing more than a full Boinc installation that is zipped up into a single file, downloaded and then unpacked somewhere in the users /home folder which gives the user full control over every file and config as the owner.

Makes for much simpler management and control.
