Synaptic Package Manager Error

I tried to open Synaptic Package Manager but this is the error messages I got:

E: dpkg was interrupted, you must manually
run 'dpkg --configure -a' to correct the problem.
E: _cache->open() failed, please report.

I know that reason why this messages pops up: I tried to download Limewire, and I left for a couple of minutes while it was downlaoding. My 3 year old son came around the computer and click on something or press a key and the computer shut down, so the installation for Limewire was never accomplished, now I did try to run the command that it states.

"dpkg --configure -a" but this is what I get:

frank@frank-desktop:~$ dpkg --configure -a
dpkg: requested operation requires superuser privilege
frank@frank-desktop:~$

Just in case someone wants to see what my source list looks like here it is:

Hope someone can help me. I want to be able to open my Sypnaptic Package Manager to download the pckg like Limewire.
