You can't. Well, actually you could, but by doing so you'll remove your desktop as well since it depends on some gnome stuff. Is that DE Unity or Gnome?
i installed it in Ubuntu 18.04 and end up with unity 7.5 .it's unity, which means it is before 18.04
what version, Leonardo?
I wonder if Ubuntu 18.04 with Unity 7.5 is still using a number of Gnome apps?now i wanta to remove gnome- setting " settings"
