[Bug 885523] [NEW] update-manager could not inialise package information

[Matt B]

Public bug reported:

When running update manager I get the following message:

-----------------------------------------------------------------
Could not initialise the package information

An unresolvable problem occurred while initialising the package
information.

Please report this bug for the 'update-manager' package and try to
include the following error message:

'E:Encountered a section with no Package: header, E:Problem with MergeList /var/lib/apt/lists/extras.ubuntu.com_ubuntu_dists_natty_main_i18n_Translation-en, E:The package lists or status file could not be parsed or opened.'
--------------------------------------------------------------
When I click on close the update-manager exits, and I have not been able to run update-manager or update my system.
I have tried running update-manager with ubuntu-bug and apport-cli, but in both cases I was told:
*** Error: Invalid problem report

Could not determine the package or source package name.

I am running Ubuntu 11.04, and the update-manager is version 0.150.2
