I recently installed Ubuntu 14.04 on my computer and now I want to change my desktop environment to Gnome 3. I have seen many methods to install Gnome 3 but now I am confused which method should I follow. Please tell me if I can install Gnome 3 with just these commands without any other commands like adding repositories etc.
sudo apt-get install gnome-shell
&
sudo apt-get install ubuntu-gnome-desktop
