When trying to install new packages, either manually or with muon, I get these errors:

jon@jon-desktop:~/Apps/mendeleydesktop-1.5-dev4-linux-x86_64/bin$ sudo apt-get install kupfer

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 kupfer : Depends: python-keybinder but it is not going to be installed
          Recommends: python-wnck but it is not going to be installed
 linux-headers-generic : Depends: linux-headers-3.2.0-20-generic but it is not installable
 linux-image-generic : Depends: linux-image-3.2.0-20-generic but it is not installable
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
