Couldn't we ask everyone to stop using the "reply to all" button?

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
