E: Some index files failed to download, they have been ignored, or old ones used instead.

Is the repo down or is it on my end: I never had any error prior errors message during my updates? And how do I troubleshoot* that?

* Changing server did not help

Seems like that is not a valid PPA. I looked at ppa.launchpad.net and it was not listed. I would check your software sources in System -> Administration -> Software Sources and make sure there are no bad entries.

These are the 2 PPA lines generating an error 404 error message (bad URL), I had to uncomment, see: print-screen.

How did they in my source file? Are they legitimate or related to some other PPA in anyway? Thanks for some input.
