I'm encountering the same bug on xubuntu-15.10:

$ sudo apt-get upgrade
Reading package lists... Done

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 libpng12-dev:i386 : Depends: zlib1g-dev:i386 but it is not installed
E: Unmet dependencies. Try using -f.
