PR2 upgrade, sources http://packages.willowgarage.com

edit

I just wanted to update - upgrade the robot (with the usual sudo apt-get update && sudo apt-get upgrade) within the robot. Nonetheless it cannot be done since the robot cannot connect to "http://packages.willowgarage.com" it seems the server has been down since some time already (I tried last week too). Anyone has any workaround this?

In my source files there is no packages.willowgarage.com. So I don't know who is calling this server. I copy the files next.

In my source.list file:
