Yesterday I upgraded my version of Ubuntu. In stead of Gnome I now have the Unity environment. I'm not sure I like Unity better, so I'll give it a probation period to see if it's any good.
What I really do not like though, is the Global menu bar. After googling I found that I had to enter:
sudo apt-get remove appmenu-gtk3 appmenu-gtk appmenu-qt
If I do that I get the error message:
E: Unable to locate package appmenu-gtk3
Can anyone tell me what I'm doing wrong here and explain how to fix this problem?
