Title:
  update-manager will not update, throws error message

Status in “update-manager” package in Ubuntu:
  New

Bug description:
  update-manager crashes with the following error message.

  'W:Duplicate sources.list entry http://archive.canonical.com/ubuntu/
  oneiric/partner i386 Packages (/var/lib/apt/lists/archive.canonical
  .com_ubuntu_dists_oneiric_partner_binary-i386_Packages), E:Encountered
  a section with no Package: header, E:Problem with MergeList
  /var/lib/apt/lists/mirror.as29550.net_archive.ubuntu

  clicking on the running window or by PID.
