I noticed while troubleshooting boinc running under Linux Mint 21 that the only Mint 21 computers that had no problem with boinc were ones that had HD with older down loads of boinc. All say that they are v7.18.1. The new downloads also say they are boinc v7.18.1 but when trying to start boinc manager I get an error message saying "illegal instruction".

Trying to figure this out I stumbled across:
"There have been reports that some recent Ubuntu repositories have installed a broken version of BOINC in their repositories - it claims to be v7.18.1 but they appear to have packaged Android sources, rather then x64 sources".

Does anyone know anything about this?

you'll have to take it up with the maintainer of those repositories, either the Mint/Ubuntu devs, or whoever runs the PPA if it's a PPA.

the BOINC team just provides the code, but have nothing to do with what's built and put in various repos.

The earliest report I can find is message 107883, from 18 Apr 2022. Read on from there.

I used software manager to uninstall every boinc thing it had installed.. After fighting with this for way to long I then discovered that using the software manager to install the "boinc manager flatpack" gives you a different newer version of boinc. I then used project manager to install boinc client and now everything works.
