You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 ipython : Depends: python-decorator but it is not going to be installed
           Depends: python-pexpect but it is not going to be installed
           Depends: python-simplegeneric but it is not going to be installed
 python : Depends: python-minimal (= 2.7.5-5ubuntu3) but 2.7.12-1~16.04 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
