Probe Basic Tool Setter questions

What are the dependency names?

Is it the 4 listed at the end?:
linux-image-6.1.0-30-rt-amd64
linux-image-6.1.0-30-amd64
linux-image-amd64
linux-image-rt-amd64

I tried
chris@PM-833TV:~$ sudo apt install linux-image-6.1.0-30-rt-amd64

It came back with the same error and those 4 listed.

Which link did you use to build the iso?

This is what I found: linux-image-6.1.0-30-rt-amd64
Linux 6.1 for 64-bit PCs, PREEMPT_RT (signed)

I clicked on mark for reinstallation and then clicked apply.
It came back with:
E: Internal Error, No file name for linux-image-6.1.0-30-rt-amd64:amd64

Ok, have you installed linuxcnc yet?

This may be easier to chat in real time

People who follow random methods to install Linuxcnc are bound to  end up with issues sooner or later as things change
Install using the image on the downloads page and install probe basic etc from repositories
This will mean you get better support as people like Lcvette will be dealing with a known environment.
