After running update manager these are the error messages I get...

E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_precise_main_i18n_Translation-en
E: The package lists or status file could not be parsed or opened.
E: _cache->open() failed, please report.

Software manager has stopped working also

I am using Linux Mint Maya. What is wrong?

You have a broken package list. This can usually be repaired by manually inspecting the file, but I am not capable of explaining a general method to do this. Removing the file in the error message, waiting a bit and calling the update manager again might fix the problem. – Gilles Nov 7 '12 at 0:58
Hi Thanks, fixed it.... There were 2 files in the list folder that were web pages, with that same file name.. (don't knot how they got there).. once deleted all works fine :-) THANKS..... – keith Nov 8 '12 at 0:44

One possible solution would be to remove all files in /var/lib/apt/lists/:

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

Then run the manager again or sudo apt-get update.

Did the trick for me.
