I recently installed Ubuntu 18.04 and I'm not keen on the desktop environment. I want the desktop env. I used to have in Ubuntu 14.04. How can I get it?
I've attempted to use this answer, but when I try to install the Unity's 7.2.5 version using the command:
apt install unity=7.2.5
it gives me
E: Version '7.2.5' for 'unity' was not found
For sure I need to add a PPA for this, but which one!?
