The boinc for Ubuntu 22.04 LTS went south a few weeks back, and I have been waiting patiently for an update. I had been running the flatpak install. Both flatpak and apt install version fail, differently. Flatpak fails to link, and apt install gets illegal instruction.

Can you be a bit more explicit about what has happened when it, "went South" If the problem were affecting all with 22.04LTS I would expect to see several posts about this by now.

Should have said, specific.

I posted details on boinc users but I guess the developers do not read that. I would expect both to run without special procedures, as the online doc and past experience does not imply otherwise:

I did some digging inside files in the flatpak dist and discovered the right launch for boincmgr flatpak is:

/usr/bin/flatpak run --branch=stable --arch=x86_64 --command=boincmgr edu.berkeley.BOINC

But it balked at the fact that I moved the files off my ssd and put a symlink to a HD dir in their place. I seem to have broken something by moving the files to my hard disk from my ssd. When I moved the files back, it launched and found my old projects. So apparently moving the files to a different disk is a bit more involved. It would be nice if the code was not symlink adverse. Maybe I have to move the parent dir and all the flatpak app subdirs.

Flatpak run is so complicated. You;d think it would put a viable script somewhere normal. Was it a failed install? Did I need to reboot after? Not seeing any online help to discover how to more properly install and run flatpak boincmgr/boinc.

Not sure why the other install does not work.

I have stopped using both deb and flatpack myself, opting to compile from source but tracking down the packages containing the required libraries can be time consuming.

Maybe if I delved into the souce I could fix the hatred of symlink problem! I have been there in open source land before!

I recommend you install BOINC 7.20.5 from this PPA: https://launchpad.net/~costamagnagianfranco/+archive/ubuntu/boinc

I'm using it on Pop OS 22.04, which is based on Ubuntu 22.04 and this version of BOINC works fine.
It's possible I had to do something after installation so the BOINC manager can communicate with the client (not sure - that problem may have been with some other BOINC version on Ubuntu 20.04).
