[Bug 1057213] [NEW] Update Manager - Failed to load package list

[youoweadam]

Public bug reported:

I receive an error message when attempting to open the update manager
(as prompted automatically).


Title: backend_helper.py

Header: Failed to load the package list

Body: This is a serious problem. Try again later. If this problem
appears again, please report an error to the developers.

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


Additional Information:
Release: Description:	Ubuntu 12.04.1 LTS (64bit)

_Cannot provide version of the package, as the package information is
what is failing to load._

I expected the update manager to open, new versions of packages to be found and installed.
The update manager window does not open, and I am shown the above error window instead.

** Affects: update-manager (Ubuntu)
