A few things to try:

1. Boot to Recovery mode and run the dpkg option. See if that cleans it
up for you. If not, then using the Recovery mode menu change to root
with networking & change the permissions there. You may have to change
the /etc/apt/sources.list back to only maverick references if it still
retains the natty references.

2. If all else fails, you can do an in-place reinstall. Using a liveCD,
select to install & manually configure your install. Select the existing
partition & be sure to NOT format. If you need detailed instructions on
how to do an in-place reinstall post back - but my first recommendation
would be to try #1.
