Check out this article. http://www.liberiangeek.net/2010/10/fix-requires-installation-untrusted-packages-error-ubuntu-10-10-maverick-meerkat/

Even if they are talking about version 10.10 i believe the solution they provide will help you. The key is to use the underlined number and make sure you update your package repository.
