Exactly.

I have a pb ,

inuxcnc-uspace:
 Dépend: libboost-python1.62.0  but it is not installable
 Recommande : linuxcnc-doc-en mais ne doit pas être installé ou
    linuxcnc-doc

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"

I did this, I tried, but he tells me he can not find the dependence.

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:

 

Wow, that is a full image converted to text !
Did you check this:
forum.linuxcnc.org/9-installing-linuxcnc...nd-easy-installation
It works for ubuntu 18 also.

No, I already have the last version installed on this "Linuxcnc 2.9pre" distribution, you told me that the switchkin was already integrated and that it was enough to copy my configuration files. Why do all this procedure. I apologize but I really have trouble understanding
