When trying to install anything:
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
colord : Depends: libsane (>= 1.0.11-3) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
I tried running apt-get -f install and apt-get install libsane with no luck.
