[Bug 1030027] Re: update-manager corrupts package information behind paywall

[Tyler Hicks]

Thanks for taking the time to report this bug and helping to make Ubuntu
better. We appreciate the difficulties you are facing, but this appears
to be a "regular" (non-security) bug.  I have unmarked it as a security
issue since this bug does not show evidence of allowing attackers to
cross privilege boundaries nor directly cause loss of data/privacy.
Please feel free to report any other bugs you may find.

** Visibility changed to: Public

** This bug is no longer flagged as a security vulnerability

Title:
  update-manager corrupts package information behind paywall

Status in “update-manager” package in Ubuntu:
  New

Bug description:
  Error message from update-manager:

  E:Encountered a section with no Package: header, E:Problem with
  MergeList /var/lib/apt/lists/us.archive.ubuntu
  .com_ubuntu_dists_precise-updates_multiverse_binary-i386_Packages,
  E:The package lists or status file could not be parsed or opened.

  Background: I ran update-manager while connected to a hotel network
  that redirects any HTTP access to a "pay us for Internet access" page
  until you've agreed to pay.  At the time I ran update-manager, I had
  not yet agreed to pay.

  Now 61 of the 154 files in my /var/lib/apt/lists directory consist of
  the HTML of the "pay us for Internet access" page.

  lsb_release -rd:
  Description:	Ubuntu 12.04 LTS
  Release:	12.04

  apt-cache policy update-manager:
  E: Encountered a section with no Package: header
  E: Problem with MergeList /var/lib/apt/lists/us.archive.ubuntu.com_ubuntu_dists_precise-updates_multiverse_binary-i386_Packages
  E: The package lists or status file could not be parsed or opened.
  [probably the files the information was in are corrupted]
