LinuxCNC on Linux Mint 20 quick and nearly easy install

The repository was added earlier. But deb packages from Buildboot need Python 3.7.  Writes can be updated and does not update.

Well the thing with Python has gotten to be absurd, nothing works any more.
Did you see this?

Thanks for your attention, I've seen and tried this. Some forum members update linuxcnc every day but don't share how. I think it is necessary through python env like django but I do not have enough knowledge.

Not the same thing/howto/ISO.
The one you think it is, was for Mint 19.2 by Beagle. He was very good at it, shame he left.
This one is done by Snowwy and it is for Linux MX, it is lighter on resources although it boots slower than Mint.
The Python issue has nothing to do with the environment, it suffered to much changes lately to improve security so most of the old stuff does not work with the new versions. So Django will not help.

I know I am reviving an old thread but I very much want to get Linuxcnc working on Linux Mint. Everything went well for me, but I need kernel headers for my wifi dongle to work. It is unable to find my headers. I followed the instruction for installing kernel headers but got caught by a circular dependency… gcc-6 requires cpp-6 and cpp-6 needs gcc-6 so I can install neither and therefore can’t get my the wifi drivers to recognize the 4.9 kernel headers. Thank you!
