Error install LinuxCNC to Debian 12

Thanks.  However, the Ubuntu 22.04.01 remains installed.  Disabling Secure Boot at UEFI Firmware Settings allowed me to dual boot.  The Grub might require an update-grub if Secure Boot enabled.  www.linuxfoundation.org/blog/blog/classi...ting-grub-2-on-linux
 

Umm, your ubuntu is not running preempt_rt  and I think it is a paid option. You can't control a machine with Linuxcnc without it.

LinuxCNC is installed on Debian 12 presently Preempt-RT.  The Ubuntu is a separate operating system.  However.  Did Debian and LinuxCNC require another Linux operating system to cross function because Debian too lightweight generally?

I don't know where you got the idea about Linuxcnc requiring anything but Debian.
Debian is certainly not lightweight. Ubuntu is actually a fork of Debian.

So if you have Debian and Linuxcnc on your system, why add another Linux distro?

Linuxcnc will run on most flavours of Linux but you may need to compile from source if Debs are not supported.

Debian Bookworm is running kernel 6.10 vs Ubuntu's 5.19.
Normally that is not an issue but in recent times, performance has been improving with each version of the kernel so 6.x is an advantage.
Plus Ubuntu only release the real time kernel with a pro subscription. Debian is truly open source so its included.
Sure you could build the RT kernel from source, but with Debian its all done for you.

Probably because he likes how it looks.
 

But good looks don't run CNC machines in real time without stumping up with $25 a year. What a crock!
Ubuntu 22.04 the OP is using does not include the linuxcnc-uspace package.
CNC machines need good looks in the HMI, not in the OS.
 

The less eye candy the better.

Why pay $25 a year when you can roll your own kernel ?

Linux is about freedom of choice and binding one app to just one distro isn't quite what it's all about. Tho I understand the reasons for using Debian. And supporting all the Distros would be a bit crazy. Sorry rethought that, a lot crazy.

I think the issue was installing the RT kernel on Debian cos for some reason someone at Debian was asleep at the wheel and added the RPi stuff to the amd64 distro (not the net install).

Vaguely, I thought I read somewhere years ago that Debian 9 or 10 would require another Linux OS and now wonder if it had something to do with dual booting. Anyhow, I could use the Ubuntu OS for miscellaneous.

Debian, 9,10,11 and 12 are stand alone Linux distributions just like different versions of Ubunu released over the years.

In any case, Debian 12.1 was released yesterday and the rpi issue should now be fixed in that release.
