apt 404 error when when updating with a PPA

sudo apt-get update command always gives me errors. It's been days since my package lists have been updated. Can anyone help me to correct it?
Here is the Screenshot:

It looks like a spelling error in you sources.list. Apt should be fetching

http://ppa.launchpad.net/openoffice-pkgs/ppa/ubuntu/dists/maverick/main/binary-i386/*

, but you are missing the a in /ppa/

Update after you posted sources.list:

deb http://ppa.launchpad.net/openoffice-pkgs/pp/ubuntu maverick main

should be

deb http://ppa.launchpad.net/openoffice-pkgs/ppa/ubuntu maverick main

And ditto for deb-src

Update 2:

Actually, you appear to have both the correct spelling and an errornous spelling, so you should just remove the lines with the missing a's.
