“Problem with MergeList” error when trying to do an update
When I try to start my update-manager, I get the following message.
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/dk.archive.ubuntu.com_ubuntu_dists_natty_main_binary-amd64_Packages, E:The package lists or status file could not be parsed or opened.'
Where do I go from here?
