Missing command on installing_on_ubuntu_precise?

Looking at the repo

[strike]There are normally only 2 arguments suite and components[/strike]
EDIT:
Actually not true, ignore, see next post

Suddenly realised the whole confusion was being caused by this forum, which removes the http:// section
from what it recognises as being a URL in the body text

What you want on a line in your sources.list is:

This works even when added to a Jessie amd64 system, insofar as fetching the Packages and Release files anyway
