[Bug 794694] [NEW] update manager could not initialize the package information

[rjonnal]

Public bug reported:

Binary package hint: update-manager

I'm running 11.04 on a Lenovo W510 laptop. I was not trying to install
an application or trying to run an update. I get a red circle with a
white horizontal bar through it as an icon in the panel at the top of
the screen. When I click on it (or try to run System -> Update Manager)
I get this error message dialog:

Could not initialize the package information

An unresolvable problem occurred while initializing the package
information.

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

'E:Encountered a section with no Package: header, E:Problem with
MergeList /var/lib/apt/lists/us.archive.ubuntu
.com_ubuntu_dists_natty_main_binary-amd64_Packages, E:The package lists
or status file could not be parsed or opened.'
