How do I reinstall Unity?

I installed Unity 5.0 to test it but I am having many problems with it, for example, the lenses don't work. But when I tried to downgrade, it didn't work.

I tried: sudo ppa-purge ppa:unity-team/staging

And I got the following warning:

PPA to be removed: unity-team staging Warning: Could not find package
list for PPA: unity-team staging

I used the article how to install Unity 5.0 in Ubuntu 11.10 to install Unity 5.0.

How can I downgrade from Unity 5.0? Thanks!

You need to have the ppa enabled in your sources before running ppa-purge or if quiting a ppa-purge attempt. (1st thing ppa-purge does is disable the ppa to be removed

So open your software sources (software-properties-gtk), re-enable the ppa & then update your sources -

sudo apt-get update

There is likely no way ppa-purge is going to do a clean, complete job so before using i'd strongly advise to install synaptic.

Then run your ppa-purge command, your best bet may be to accept the 1st solution, Y, & then answer Y to any other presented until it does it's thing.

Once finished Do Not log out or restart

Open synaptic, click 'Reload', then search gnome-session & mark for install if it's not installed. Then search unity & mark unity for install or re-install.

Additionally search nautilus & mark libnautilus-extension1 for reinstall, check & make sure that nautilus & nautilus-data are installed, if not mark also & apply.

If desired you could search ubuntu-desktop and mark for reinstall in lieu of above, just make sure the packages I've mentioned are installed before you log out or restart

Also note that unity-2d may need to be reinstalled

Good luck...
