I was having problems installing MongoDB with NPM and I found someone saying that the problem is related to the fact that I had Python 2 and 3 installed. So I removed Python 3 and after this many Ubuntu apps disappeared.
After rebooting, Unity stopped working and I can't open terminal, view my apps, etc.
I've reinstalled unity and also tried to install gnome, but it still doesn't work.
What do I have to do?
In my case the Unity plugin being disabled was the problem: http://askubuntu.com/questions/453482/update-to-14-04-unity-is-not-loading-after-i-login-to-the-admin-profile-after/
