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

Bug description:
  I can't have my update manager launched and can't get any new software
  or updates.

  1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
  UBUNTU 12.04 LTS

  2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
  Can't find it. 
  Message:E: Encountered a section with no Package: header
  E: Problem with MergeList /var/lib/apt/lists/extras.ubuntu.com_ubuntu_dists_precise_main_binary-i386_Packages
  E: As listas de pacotes ou os arquivos de estado não puderam ser analisados ou abertos.
   
  3) What you expected to happen
  I wanted to install a new software and update existing ones

  4) What happened instead
  Didn't open at all

  This is not the first time it happened. But I've already done a lot of
  things and reinstalled Ubuntu 3 times in the last 3 months - and
  really wouldn't like to do it once again to get it working properly.
