Red exclamation point in triangl up there is scareing me when i click on it this shows up:

The update information is outdated.This may be caused by network problems or by a repository that is no longer available. Please update manually by clicking this and then selecting 'check for updates' and check if some of the listed repositories fail.

So I do that and once its done checking this comes up:

This is the list of packages pmcenery offers. You should review them and make sure that these are packages that you need/want. If you don't you're better off removing them from your Software Sources (under Other Software tab) in Ubuntu Software Center.

If you do want these software packages, test out those ppa.launchpad.net links in your browser and sift through the directory till you find the folder that closely matches the folder Terminal is looking for and correct the difference in Software Sources. The problem is likely that the links are just broken and need to be updated.
