Ubuntu :: Can't Update Or Install Apps

I am having a problem that I cant update or install apps. I am using Natty under ubuntu classic and have tried these two posted fixes but they wont work

sudo mv /var/lib/dpkg/status /var/lib/dpkg/status-RENAMED
sudo cp /var/lib/dpkg/status-old /var/lib/dpkg/status
sudo apt-get update && sudo apt-get upgradeCheers,
sudo rm /var/lib/apt/lists/* -vf
sudo apt-get update

these didnt work and dont know where to start to look in order to fix this myself this is what I get when I run package manager and apt-get update.

E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/us.archive.ubuntu.com_ubuntu_dists_natty_multivers e_i18n_Translation-en
E: The package lists or status file could not be parsed or opened.
E: _cache->open() failed, please report.
