Can anyone shed some light for me on why the above
ubuntu mirror doesn't work. Yep, I googled on it and
find the link that shows all, main, restricted, universe
and multiverse with each containing files. I get error
Err http://archive.ubuntu.com hardy-proposed/multiverse Packages
  404 Not Found [IP: 91.189.88.46 80]
on all, main, restricted, multivers and universe.
Appreciate any insight on why this is not working or if the
url has changed its address and why I don't pick that up googling.
TIA,

Leonard Chatagnier
