Installing LinuxCNC 2.9 or Master on Linux Mint 21

If you compile you can even use python 3.8.10. Python 3.11 seems to be a packaging requirement not a compiling requirement. it used to be easy to change it now it seems to read to python version of the system when building the deb, rather then using a minimum version.

I have to admit that I struggled a bit to wade through this nearly year-long thread, apologies if I missed something.
Has anyone figured a way around the python3.11 issue for Mint (which I'm using elsewhere too) and LinuxCNC 2.9?  Is building from 2.10 an option on mint?  Or do I need to use Debian?

2.8.4 is not an option, at least not without some real contortions, due to missing kernel modules to support a more recent AMD GPU.

Not bothering with this anymore since LinuxCNC is officially in the Debian repos and Debian has a Mate edition, so it is the same thing, granted Mint is still somehow much faster at booting.
Get the Debian 12 BookWorm Mate edition ISO, i am pretty sure you can install Mint-Y-blue or whatever Mint theme you want, so it even looks and feels the same.

I don't seem to have too much trouble building the most recent git pull of 2.9 on Mint 21 Vanessa.

Start here for a Debian 12.1 config and select mate instead of xfce if you must:

I just built a Debian 12 box on my work PC and am finding Cinamon to be quite nice too.

You can't seem to specify the python minimum version anymore on the build system.
You would need to compile linuxcnc for mint. (I still use compiled 2.9/master for older Mint)
I bet after that you could use linuxcnc to make a mint deb. IIRC the python version is pulled from the deb making system.
