I just added the reference to the ISO for completeness.
And wanted to pint out that my repos can be used to install Linuxcnc on a pre existing installation of Mint 19.x.

Well, I need some help... that is getting to be a theme...
I have a new used i7 4gen desktop and I'm trying to get a real time os installed to run Linuxcnc. i have done a lot of different things(linux installs of various flavors and kernel source compile) and now I'm trying the procedure described in the first post of this thread. I've installed linux mint xfce 19.3.
I followed the steps and I can still reboot and run which is further than I've been before but I'm getting max jitter of 6160975ns on the servo thread and 6914234ns on the base thread. No kidding. My older celeron laptop was much better than that. And apps seem like they are very slow starting up and running. I must have buggered something up.
When the latency test starts:
eddie@shop-cnc:~$ latency-test
Note: Using POSIX non-realtime
Waiting for component 'lat' to become ready................................................................................
Note: Using POSIX non-realtime
eddie@shop-cnc:~$ uname -a
Linux shop-cnc 5.3.0-53-generic #47~18.04.1-Ubuntu SMP Thu May 7 13:10:50 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
It doesn't say anything about rtPreempt or rtai or real time so I thought maybe i did something wrong so i ran through the installation procedure again and got to
eddie@shop-cnc:~$ sudo apt-key adv --keyserver hkp://keys.gnupg.net:80 --recv-key EF1B07FEE0EE663E
Executing: /tmp/apt-key-gpghome.jUqZoBdORi/gpg.1.sh --keyserver hkp://keys.gnupg.net:80 --recv-key EF1B07FEE0EE663E
gpg: connecting dirmngr at '/tmp/apt-key-gpghome.jUqZoBdORi/S.dirmngr' failed: IPC connect call failed
gpg: keyserver receive failed: No dirmngr
I don't have a clue what that is saying.This is the second time I've run through the commands so maybe I can't do that but once. I have no Idea.
Any suggestions from anyone?

sudo apt install dirmngr
and hold down shift and ctrl when booting to show the GRUB menu, choose a kernel with RT in the name.
The one you are using is not RT.
After installing RT kernel do not use
sudo apt upgrade
use
sudo apt dist-upgrade

many thanks!
The dirmngr was already installed.
I rebooted with the shift and ctrl and it booted without going thru a grub menu but I got this:

note the message on the first and second runs of the latency test. Is this something I need to investigate?
I have a new used graphics card and a wifi card to install then I can start integrating to my cnc. I have a mesa 7i96 for it.
Thanks again.

Wait, you did the first tests without rebooting the PC???
Nice, now you can move on to setting up the machine and making some chips.
Thanks for reporting back.

well, I thought I did. Nearly positive I did. But I really don’t see how I could have looking back at it. That is the first time I’ve ever screwed up.

New here and have a question.
I have followed the instruction on the first post in this thread and have successfully installed as described.
Is there any reason that I should not let the system perform updates?
Thanks

You can do:
sudo apt update
sudo apt dist-upgrade
as much as you like and it will update everything.
But will not allow new kernels and new Mint version that would render LinuxCNC non functional.

Wanted to try out the o so widely praised mint, so I dug out this thread.
wgetting the mentioned kernel failed, as "http.us.debian.org/" could not be found. I searched for a similar kernel here , downloaded ist and installed it.
I got this

It works here:
And the source code and unstable packages need to be enabled in the software sources from the main menu>administartion
Edit:
I did manage to install and run the 5.6 kernel, but the latency was terrible.
