[Bug 988841] Re: cannot use update manager

[Jackson Sandberg Lawler]

You may mark this as solved.  All I had to do was find every file that
had been changed as described previously and delete all of its contents
and then run update-manager again and it worked.  I am sorry if I seemed
flustered; it was unintentional if I came across as such.  I don't know
what caused this issue, but I think update-manager did something wierd
when it tired to look for updates and was intercepted by the login
prompt.

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.
