Comment 34 for bug 346386

Absolutely perfect solution. Worked extremely well. I knew I had a problem with one of the files, and it should have been deleted. However I didn't known about clean, update and upgrade (which I guess is what the Update-Manager does).

Thank you for the quick response.

> TEST CASE:
> 1) Ensure /etc/apt/sources.list points to archive.ubuntu.com
> 2) Setup proxy server to block access to archive.ubuntu.com and return something like http://people.canonical.com/~brian/tmp/not-packages.html
