How to reinstall Unity?

Question

A few months ago I installed this ppa from the recommendation of this answer. It now turns out that it's buggy as hell and breaks nearly everything almost all the time.

I tried removing the ppa and reinstalling unity, but I get the message Reinstallation of unity is not possible, it cannot be downloaded.

How do I go back to using unaltered Unity?

If you have already removed the ppa, you have to add it again for this to work:

sudo apt-add-repository ppa:mc3man/systray-white
sudo apt-get update

Next, purge the ppa, which will remove it from your sources and restore the packages to the official version:

sudo ppa-purge ppa:mc3man/systray-white

In case ppa-purge is not installed, do:

sudo apt-get install ppa-purge

@Jobin Agreed, although purging the ppa should automatically reinstall the package. – animaletdesequia Jan 11 '14 at 07:54

I reinstalled the ppa and then purged it, that worked. Thank you, this has been bugging me for months. – iirelu Jan 12 '14 at 01:18
