I need to get rid of the GNOME Desktop Environment which has been installed by default when I updated my pc from 15.10 to 16.04.
After a while, I found myself not only with GNOME DE, but also with Cinnamon alongside (in the login screen, I could choose at least five or six DE!)
Now I am using Unity, and I'm happy with that, and I successfully uninstalled Cinnamon, but now I'm afraid that after uninstalling GNOME I will mess up the Unity DE, since I see many packages running in unity with the packagename starting with gnome-… Would someone mind to help me? Thx in advance

Uninstall ubuntu-gnome-desktop and it's dependencies
This will remove the ubuntu-gnome-desktop package and any other dependant packages which are no longer needed.

If you also want to delete your local/config files for ubuntu-gnome-desktop then this will work.
Caution! Purged config/data can not be restored by reinstalling the package.
