Installing LinuxCNC 2.9 or Master on Linux Mint 21

Python, QT, Wayland, what's next?
At one point in time, the buildbot version of LinuxCNC required Python under 3.6 and over 3.9 at the same time! I am sure i posted about that here somewhere, it is astonishing how much mess Python 3.n has made, with everything, not just with LinuxCNC.
I did waste quite some time trying to figure out how to make an appimage for LinuxCNC, from experience with plenty of apps in that format, they do work perfectly, no installation, no dependencies as everything is included, etc etc, but the tutorials online are useless and copied/pasted from the same source, information's are all about what i do not need, and none mention dependencies. Or my search-fu has failed miserably.
This would have been the best solution as it would run on almost anything, just download, make executable, run.
And since uspace version works as sim if there is no real time kernel, all would be good with the world!
Need realtime? Install kernel.

Before anyone takes off at a tangent, no "snaps" and no "flatpak", but definitely NO SNAPS! Flatpak is bearable, somehow, maybe.

I tried to make a deb on a lower python version but something failed with translations.

Try it with --no-docs
Usually that works and takes much less time to compile.

Yeah, Debian is the way now as it is officially in their repos, not sure when Bookworm comes out but it can be downloaded and used.
RodW has a good tutorial for it, i think, been spaced out lately so not "Mr Current affairs" right now.
