Enabling third-party software sources

[emerick7]

I upgraded to 11.04, and in the process it said third-party software sources needed to be disabled.

Now, when I go into Software Sources nothing happens (the form doesn't open up).

Is there a command line prompt to enable third-party sources? I think this might be why my keyboard/mouse aren't working.

Hey, I don't know if you figured this out yet but if you didn't just follow these steps:

1. Click on the white Ubuntu logo in the upper left corner. A black menu will open up.
2. Type "software sources" in the search box.
3. Click on the "Software Sources" icon that appears in the menu.
4. Type your password in the window that appears.
5. Click on the "Other Sources" tab that appears and scroll down. You will see at [at the bottom] all the sources that were disabled when you upgraded. Just click the check boxes to re-enable them. You'll then be prompted to "download package information" (or something like that). Say yes.

I hope that helps.
