How to fix a “Problem with MergeList” or “status file could not be parsed” error

I recently got this error, usually may happen after a Heroku toolbelt setup

E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_natty_main_binary-i386_Packages
E: The package lists or status file could not be parsed or opened.

you wont be able to update through terminal too

Open Terminal and issue this command

sudo rm -vf /var/lib/apt/lists/*

Generate a new list by doing a update

sudo apt-get update

Happy Hacking 🙂
