Please report this bug against the 'update-manager' package and include the following error message: 'E:Encountered a section with no Package: header, E:Problem with MergeList /var/lib/apt/lists/us.archive.ubuntu .com_ubuntu_dists_intrepid_universe_binary-amd64_Packages, E:The package lists or status file could not be parsed or opened.' WORKAROUND: Remove problematic files from /var/lib/apt/lists/ and rerun apt-get update. In the event that one is connected to a network with a proxy server that returns html pages (like a web page requesting you to login) and not package list files. Those html files will get downloaded to /var/lib/apt/lists/ and prevent someone from using a package manager until the problem html pages are removed. TEST CASE: 1) download the dummy-proxy attachment from this bug report 2) run dummy-proxy (python dummy-proxy) on a precise system (this simulates a proxy that is not allowing access to archive.ubuntu.com and gives you garbage html instead) 2.5) Execute 'sudo -i' in a terminal 3) Execute 'http_proxy=http://localhost:8080 apt-get update' in same terminal 4) Observe the following error messages in your terminal: W: GPG error: http://archive.ubuntu.com precise InRelease: File /var/lib/apt/lists/partial/archive.ubuntu.com_ubuntu_dists_precise_InRelease doesn't start with a clearsigned message W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/precise/multiverse/i18n/Index No Hash entry in Release file /var/lib/apt/lists/partial/ archive.ubuntu.com_ubuntu_dists_precise_multiverse_i18n_Index W: Failed to fetch gzip:/var/lib/apt/lists/partial/archive.ubuntu.com_ubuntu_dists_precise_multiverse_source_Sources Encountered a section with no Package: header 5) Stop dummy-proxy 6) Execute 'sudo apt-get update' in a terminal 7) Observe the following error message: Reading package lists...
