FAHControl does not run on Debian Bullseye because it relies on Python 2.
Could this repository be updated to work with Python 3? It no longer works for the current Debian Stable, which is Bullseye. From the pull request list, I can see there are two separate ports to Python 3 already (https://github.com/FoldingAtHome/fah-control/pull/56 and https://github.com/FoldingAtHome/fah-control/pull/70). Why have they not been reviewed and merged?
I recommend we start with https://github.com/FoldingAtHome/fah-control/pull/70.
There are pull requests open for almost 2 years, which add Python 3 compat. Would be nice if someone cared to merge the updates, as Python 2 has been sunset for 1.5 years already, with more and more Linux distros no longer providing packages for it.
I'm currently using the code from fork cdberkstresser/fah-control, which works nicely.
