Software sources wasn't showing up in the unity menu when I searched for it but it said it was installed in the software center. I uninstalled it and got the message:
If you uninstall Software Sources, future updates will not include new items in The Ubuntu desktop system set. Are you sure you want to continue?
Install Packages using the apt protocol
The ubuntu desktop system
I reinstalled it and still couldint find it.
I found the answer here Software Sources not found in Unity Dash Search
So now I have it back, but im afraid that since I initially uninstalled it that I'm going to not get the "future updates" even thought I reinstalled it.
