This is an apt problem, you should be able to clean up by doing the following:

First try:

sudo apt-get autoremove

Which prunes any dependencies that were installed automatically, but might not be correct. If that doesn't work, move on to:

sudo apt-get -f install

Which will finish any broken or cut-off installs and fix unmet dependencies. If that doesn't work, try

sudo apt-get clean all

Which cleans up apt's working directories.

Those will generally fix all apt problems that you may have, remember to always sudo apt-get update before beginning to install anything.
