I been noticing my Ubuntu machine acting strange after I ran a Software Update.

This is the error I get. I cannot launch the software center or force a uninstall of the file/package mentioned.

'E:Encountered a section with no Package: header, Eroblem with MergeList /var/lib/apt/lists/ppa.launchpad.net_ferramroberto_java_ubuntu_dists_ precise_main_binary-amd64_Packages, E:The package lists or status file could not be parsed or opened.'

Please advise.
