Success: Install LinuxCNC-sim on debian butster?

In went over to 2.8 but with this version i had more problems with dependencies as with 2.7
On git i saw the 2.7-buster version, but after building there were also dependency problems.

Package python-gtksourceview2 is not part of the debian repositories. After downloading it anywhere else i had dependency problems with this package but debian package manager did notice the problems and suggested to solve it with some more packages.

The key was to get python-gtksourceview2 installed. Then i installed linuxcnc again and now it works as linuxcnc-sim.
I learned something new about git and compiling software, it was worth the trouble.
