You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 dh-python : Depends: python3:any (>= 3.3.2-2~)
 software-properties-common : Depends: python3:any (>= 3.3.2-2~)
                              Depends: python3 but it is not going to be installed
                              Depends: python3-gi but it is not going to be installed
                              Depends: gir1.2-glib-2.0 but it is not going to be installed
                              Depends: python-apt-common (>= 0.9) but it is not going to be installed
                              Depends: python3-dbus but it is not going to be installed
                              Depends: python3-software-properties (= 0.96.20.5) but it is not going to be installed
                              Depends: ca-certificates but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
