Bob:
Just happen to be sitting in the lab and saw the email...
Using Linux Mint 22.0 which uses flatpak for installs during updates so it's right there to try.
Yes... Your URL downloaded and doing a flatpak install was good, just supplying password and Y when needed. There was a 5.8 on that machine and it seems to have been found when the 5.10 installed brought prefs forward.
I didn't check logs to see if the JDK was changed, quick check is version 21.0.6.
Obviously need to run more checks... this is a test machine and not in production...
