(superseeded) Linuxcnc on Linux Mint 19.3 quick and easy installation

[strike]If you have used that to make a Linux Mint bootable usb stick I guess, but Win32DiskImager is simple and reliable, it doesn't try to be too clever.[/strike]

What flawour of Mint are you using ?
From what you describe, there is no initrd and vmlinuz created or they are not in the boot folder.
I wonder how did that happen ????
I have installed this same setup over 30 times till now with Mint 19.1 and 19.2 and 19.3 and it never failed.
19.3 is a simple as install Mint, install 2 kona files, install Linuxcnc 2.9. Reboot and hold ctrl/shift.
Thats it.
Again just to be sure, i use Mint 64 bit Mate edition, never tested other versions.

It is mate 19.1. The boot message says the rt kernel has an invalid signature, whatever that means. I think I will wipe out 19.1 and install 19.3 and try again. I did not see the 2.9 version of linuxcnc but will check again. It is Mate 64 bit.

Wrong files.
Try these
simosnet.com/debian/packages/Konalinux/d...t5-kona-rt_amd64.deb
simosnet.com/debian/packages/Konalinux/d...t5-kona-rt_amd64.deb
Report back.
Thank you.

I had a feeling I had the wrong files since I was using them from your first post in 2018. I just burned a usb stick with 19.3 mate 64 and I will see how it goes. Thanks so much!

Ok, I have mate 19.3 installed and running. I installed the headers and image from the links you sent. Do I need a new link for the kernel? And the link for linuxcnc 2.9. Thanks

WinUSB v3.7.0.1 will not work with Linuxmint CNC 2.9 iso -error Linux Lnitrd file not found on iso .

L[strike]ike I said use win32diskimager. Your utility maybe looking for initrd.lz which is not on the iso, the file is actually initrd.gz, some of the USB utilities do not do a raw byte by byte write to the USB stick. The image has been created as a so called hybrid image, which will boot when written byte by byte to either a dvd or a usb stick. A non hybrid image has issues booting from a USB stick.

I tested the iso multiple times using VBox and put it onto a USB stick and installed it on my Laptop. I even have a copy burnt to dvd which I've used to install.

When doing things it really helps to follow the advice given. Then if they are any issues it is easy to diagnose and fix. I'm not being an ass.[/strike]

I am sorry but I don't have a clue as to what you are talking about. I posted about running Linuxcnc on Linux Mint 19.1 Mate.

If you look at the top of my last post you will see I quoted another user.
