For me worked change the file "/etc/apt/sources.list.d/prerequists- sources.list" and change the server that wasn't responding to another one, from:
http://es.archive.ubuntu.com/ubuntu feisty-backports main/debian-installer
to
http://en.archive.ubuntu.com/ubuntu feisty-backports main/debian-installer
With that no more problem, but now I don't have a local server in my sources.list.
