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/extras.ubuntu.com_ubuntu_dists_precise_main_binary-i386_Packages, E:The package lists or status file could not be parsed or opened.'

sudo apt-key adv --recv-key --keyserver keyserver.ubuntu.com 16126D3A3E5C1192

Can you then give the output of:

sudo apt-get update; lsb_release -a

Thanks

No worries dude, that happens when the hash files for the packages go out of whack. You deleted ALL the knowledge of any packages and then re downloaded, making it clear.

Thank you for the explanation. I always try to increase my knowledge base. In doing so I try to become more of a contributor and less of a user. What is a hash file?

When I ran "sudo apt-get update" I was receiving this error:

W: GPG error: http://ppa.launchpad.net trusty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 531EE72F4C9D234C

and after reading this post, I ran the following:
