I use ubuntu, but I had problems with Unity, so I changed to use lubuntu-desktop:
sudo apt-get install lubuntu-desktop
The updating manager is now saying that there is a new version of ubuntu, and asks if I want to upgrade. Can I safely do that without getting problems with my desktop, or Unity coming back and replacing it?
Edit: I am currently running Ubuntu 12.04.5 LTS, and the update manager asks me to upgrade to 14.04.1 LTS. It would be interesting to know the answer to my question for this particular upgrade, but also generally.
