Subject: Re: [Bug 346386] Re: [MASTER] Update fails with invalid package files with "Encountered a section with no Package: header"

Has this bug been fixed or not and if it is has been fixed is the update available with Update Manager?

I had the same problem recently whilst doing an update with the Update Manager of 12.04 LTS and had to resort to the work around to fix it.

In fact, "sudo rm /var/lib/apt/lists/*" did not remove the .../lists/partial directory but I left it and did the "sudo apt-get update" successfully.

Hope someone can find a permanent solution to this.

Kayode

Title:
  [MASTER] Update fails with invalid package files with "Encountered a
  section with no Package: header"

Status in “apt” package in Ubuntu:
  Fix Released
Status in “apt” source package in Natty:
  Fix Released
Status in “apt” source package in Precise:
  Fix Committed
Status in “apt” package in Debian:
  Fix Released

Bug description:
  Binary package hint: adept-updater

  Pertinent data printed when attempting to run Updater as follows:

  An unresolvable problem occurred while initializing the package
  information.

  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)
  3) Execute 'http://localhost:8080 sudo apt-get update' in a 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... Done
  W: GPG error: http://archive.ubuntu.com precise Release: The following signatures were invalid: BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic      Signing Key <email address hidden>
  8) Remove the problematic files in /var/lib/apt/lists (sudo rm /var/lib/apt/lists/*)

  Install apt from -proposed
  1) 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   garbarge html instead)
  2) Execute 'http://localhost:8080 sudo apt-get update' in a terminal
  3) Observe the following error messages in your terminal:
  W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://    archive.ubuntu.com precise Release: The following signatures were invalid: NODATA 1 NODATA 2
  W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/precise/Release
  W: Some index files failed to download. They have been ignored, or old ones used instead.
  4) Stop dummy-proxy
  5) Execute 'sudo apt-get update' in a terminal
  6) Observe the update succeed
