Bug description:
  This bug appeared when I was trying to install teamviewer which doesn't work.
  There are some dependencies that break the installation.
  Then I tried to remove teamviewer:
  sudo apt-get remove teamviewer
  Reading package lists... Done
  Building dependency tree       
  Reading state information... Done
  You might want to run 'apt-get -f install' to correct these:
  The following packages have unmet dependencies:
   libpng12-0 : Breaks: libpng12-0:i386 (!= 1.2.54-1ubuntu1) but 1.2.50-2+deb8u3 is to be installed
   libpng12-0:i386 : Depends: libc6:i386 (>= 2.11) but it is not going to be installed
                     Depends: zlib1g:i386 (>= 1:1.1.4) but it is not going to be installed
                     Breaks: libpng12-0 (!= 1.2.50-2+deb8u3) but 1.2.54-1ubuntu1 is to be installed
  E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

  Then as suggested I tried: sudo apt-get -f install 
  Reading package lists... Done
