Schaublin 125-CNC retrofit.

Has that changed since thursday?

I do not think so.

Thanks, but that is the one which doesn't work.
I'll try the old 2.7 Stretch ISO with Preempt.

Sorry for the mess, i thought that was already in.
Back on topic, are you using a Live session or install on HDD/SSD?
Live session does not ask for password when using sudo, just warns and moves on.
During install to HDD/SSD, do not enter a root password, just move to the next screen where it will ask for a new user.
Adding a root password will set Linux to "multiuser" mode, so no amount of sudo passwords will work.

Thanks Tommy, Just a live session on the laptop today. I have a mini pc in the mail which will be the brain of the Schaublin, and will do a full install to it. I just wanted to do a couple of tests with the live session today.

Delete - screwed up the format.
