update-manager error

[cal_zlone]

After I updated my update-manager, I received this error:

------
Could not initialize the package information

A unresolvable problem occurred while initializing the package information.

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

'W:Duplicate sources.list entry http://archive.ubuntu.com gutsy/main Packages (/var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_gutsy_main_binary-amd64_Packages), W:Duplicate sources.list entry http://archive.ubuntu.com gutsy/restricted Packages (/var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_gutsy_restricted_b inary-amd64_Packages), W:Duplicate sources.list entry http://archive.ubuntu.com gutsy/universe Packages (/var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_gutsy_universe_bin ary-amd64_Packages), W:Duplicate sources.list entry http://archive.ubuntu.com gutsy/multiverse Packages (/var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_gutsy_multiverse_b inary-amd64_Packages), E:Encountered a section with no Package: header, E:Problem with MergeList /var/lib/apt/lists/ppa.launchpad.net_awn-testing_ubuntu_dists_gutsy_main_binary-amd64_Packages, E:The package lists or status file could not be parsed or opened.'
