I followed the instructions and it mostly worked for me. The kernel referenced doesn't seem to exist in that repository and it's kinda old now anyway so I installed 'SMP PREEMPT_RT Debian 5.10.13-1~bpo10+1 (2021-02-11)' from the same repository. I can report LinuxCNC works under that kernel on Mint 20.
I did struggle with signing the kernel for Secure Boot, never used that before. After spending hours following several instruction sources several times, trying both signed and unsigned kernel packages, I lost patience and disabled Secure Boot in Linux.
Other than those couple of issues it was rather straightforward following your instructions. I'll be hooking up a Mesa 7i76e, which I've also never done previously.

wget ftp.us.debian.org/debian/pool/main/l/lin..._4.9.228-1_amd64.deb
That still works, and that is the one used in the tutorial. It was 5.4 but that is not found any more so glad you found 5.10.
Secure boot is another microsoft "showed upon us" useless feature.

Thanks. All the more reason to disable it then. I'll probably do it once and for all in my BIOS just to give my ex-employer a proper finger.
My machine will be mostly standalone due to not having wifi in my barn so I'm not too worried about hackers trying to steal my woodworking template designs ... lol

I interestingly found out not to allow Linux to update the kernel, for when it reboots the RealTime kernel will provide a lovely kernel panic and refuse to start. Thankfully, the generic kernel still booted so the issue was easily fixed by reinstalling the RT kernel. I disabled automatic kernel updates on my machine which will depend on me to perform them manually and track the repository ... which I probably won't do.

Sudo apt dist-upgrade
Should take care of not updating the kernel.
I did say should as i had one PC that would upgrade the kernel despite using that, other PC do not upgrade the kernel. Must have messed up something on that PC!

Removing the linux-image-generic meta package will stop the kernel being updated. The kernel packages are not directly upgradable like, say, the LinuxCNC packages, being that they are all individual packages with unique names. Reinstalling that package will reinstate the kernel auto updates.
5.10 is very recent, recent enough that it should not need upgrading for some time. I may not mind updating every couple of years.
Linux has come a long way, I remember being on a 0.99 kernel back in the day. He says, wistfully ...

hello, colleagues. I installed everything by intsruction in the first post, but in addition to the usual linuxcnc, I need linuxcnc-dev to compile my own components, but it does not want to be installed, stating an unresolved dependency: phython-serial but it is not installable. perhaps I missed the answer to a similar question, so please tell me how to install this phython-serial correctly? I even found a deb package on the network and installed it, but the dependency remains unresolved. I would appreciate your help!

Better use the Mint 19.3 for dev stuff, 20 has a lot of issues with everything Python.
Dev version of LinuxCNC can be installed and it works (after about 20 to 30 missing dependencies) but it will still stumble and fall when trying to compile anything lightly complicated.
