This question already has an answer here:
On this machine, I installed Lubuntu 12.04 and then installed the
ubuntu-desktop package. Now there is some Lubuntu software, such as the Lubuntu Software Center, Xscreensaver, and Abiword, that needs to be removed.
There are plenty of scripts online, like this one, that describe how to get back to a pure Ubuntu desktop (after installing the
lubuntu-desktop package) by removing all the Lubuntu packages, that is, the packages that
lubuntu-desktop depends on. Can I use that script to remove the old Lubuntu packages and fully migrate to pure Ubuntu? I am worried that the script may remove some packages, like
libbluray, that Ubuntu needs.
