Ubuntu Software Updater and libpcap0.8 package Issues

Question

Ubuntu has notified me I have some updates but when trying to update I get this message...

The package system is broken: Check if you are using third party repositories. If so disable them, sine they area common source of problems. Furthermore run the following commend in a Terminal: apt-get install -f

I have followed the instructions here to disable third party repositories and I still have the same issue.

In Terminal as suggested apt-get install -f returns this...

Furthermore apt-get remove gives me this...

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 libpcap0.8 : Breaks: libpcap0.8:i386 (!= 1.4.0-2) but 1.7.4-2 is installed
 libpcap0.8:i386 : Breaks: libpcap0.8 (!= 1.7.4-2) but 1.4.0-2 is installed
 libpcap0.8-dev : Depends: libpcap0.8 (= 1.7.4-2) but 1.4.0-2 is installed
 tcpdump : Depends: libpcap0.8 (>= 1.5.1) but 1.4.0-2 is installed
E: Unmet dependencies. Try using -f.

And apt-get remove -f as it suggests comes back with this...

I have a very good idea of how this all happened but sadly have not been able to address the issue :(
