I haven't loaded up my Ubuntu OS in a while when i did this morning the Software Center kept crashing and said something was wrong so i tried sudo apt-get update and it said that the headers were missing here is the error from Terminal
Reading package lists... Error!
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/security.ubuntu.com_ubuntu_dists_quantal-security_main_i18n_Translation-en
E: The package lists or status file could not be parsed or opened.
I apologise in advance if this is a simple fix but I'm a total noob when it comes to Linux.
Thank you for your time.
