Is this for Xubuntu or the official ISO?
which distribution did you use stretch or buster?

[edit]
last question is regarding what you wrote in the "Distribution" field when you added the repositories.

1) I'm still on official debian version.

2) I used "stretch" as on the video "buster" doesn't seem to work ...

For the official debian ISO you would want to use "buster". Worked for me after I added the key with the command
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com --recv-key EF1B07FEE0EE663E
In what way did it not seem to work for you?

I did this, I tried, but he tells me that he cannot find the dependence "libboost-python1.62.0"

Not easy anyway.

I will try to put my configuration Under Xubuntu linuxcnc 2.9pre. if I just have to copy my configs files, it will be easier. But I still think I will run into other problems ...

Not easy anyway.

No, this should be a lot easier. I agree.

Have you removed the 'stretch'-repsitories you added before?
Maybe you could post a screenshot of your synaptic package manger window showing the repositories?

I am on Xunbutu where the Linuxcnc 2.9pre configuration is already installed.
I copy my configs files in the "Linuxcnc" folders
I then started linuxcnc as described, but it also doesn't work:image missing /media/kunena/emoticons/sad.png
