How do I fix a “Problem with MergeList” error when trying to do an update?
I have been reviving the following error today, because of this I cannot install any programs or update or any thing.
W: GPG error: http://ppa.launchpad.net precise Release: The following signatures were invalid: BADSIG 464AD83D4631BBEA Launchpad equinoxart
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/ppa.launchpad.net_tiheum_equinox_ubuntu_dists_precise_main_binary-i386_Packages
E: The package lists or status file could not be parsed or opened.
This code is from running apt-get update.
I also read that this could be because of un-met dependences how would I resolve this ?
