cant update or get software

this is what pops up when i try to update or go to software center
any ideas?

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/security.ubuntu.com_ubuntu_dists_precise-security_main_i18n_Translation-en, E:The package lists or status file could not be parsed or opened.'


re: can't upate or get software

Have you tried using the command line to see if you can update using sudo apt-get update && sudo apt-get upgrade ?

I'm just wondering if there's a problem with the gui software store and/or update
