[Bug 988841] Re: cannot use update manager

Thu Apr 26 23:08:56 UTC 2012

I know what happened.  Somehow, the content of every single file in my
packages directory was replaced by this by the firewall at my school
when I forgot to log in before checking for updates:

<HTML><HEAD><META HTTP-EQUIV="refresh"
CONTENT="0;URL=https://192.168.76.1:4100/fw_user_login.html?redirect=http://extras.ubuntu.com/ubuntu/dists/precise/InRelease"><meta
http-equiv="PRAGMA" content="no-cache"><meta http-equiv="Cache-Control"
content="no-cache"><meta http-equiv="Content-Type" content="text/html;
charset=UTF-8"></HEAD><BODY><b>You must login before accessing this
site.</b><p>Your browser should be redirected to the login page shortly,
or you can navigate directly there by selecting the link below:</p><a
href="https://192.168.76.1:4100/fw_user_login.html?redirect=http://extras.ubuntu.com/ubuntu/dists/precise/InRelease">Firewall
Login Dialog</a></BODY></HTML>

There are 18 files that contain nothing but that now.

Title:
  cannot use update manager

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

Bug description:
  whenever I open update-manager now, I get this message:

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

  This happened just after I told the program to check for updates.  I
  am at school and they have a filter program that blocks us (the
  students) from getting online without logging on first.  I forgot that
  I had to log on first because I opened update-manager before I opened
  my browser (where the username and password is prompted upon initial
  attempt to visit a webpage).

  First thing, I opened update manager, and checked for updates.  it
  told me to check my internet connection; that was when I realized that
  I had forgotten to log in.  So, I opened my browser and typed in my
  username and password and then got on to google just fine.  Then, I
  tried to update again, and almost immediately, I presented with the
  error message I mentioned before.

  I marked this as a security vulnerability because I think that it
  might be, since I cannot receive any updates anymore.
