  You might want to run 'apt-get -f install' to correct these:
  The following packages have unmet dependencies:
   atom : Depends: git
   google-chrome-stable : Depends: libappindicator1 but it is not going to be installed
  E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
