You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 libpython2.7 : Depends: libpython2.7-stdlib (= 2.7.15-4ubuntu4~18.04.2) but 2.7.17-1~18.04ubuntu1.6 is to be installed
 libpython2.7-dev : Depends: libpython2.7-stdlib (= 2.7.15-4ubuntu4~18.04.2) but 2.7.17-1~18.04ubuntu1.6 is to be installed
 libpython2.7-stdlib : Depends: libpython2.7-minimal (= 2.7.17-1~18.04ubuntu1.6) but 2.7.15-4ubuntu4~18.04.1 is to be installed
 python2.7 : Depends: python2.7-minimal (= 2.7.15-4ubuntu4~18.04.2) but 2.7.15-4ubuntu4~18.04.1 is to be installed
             Depends: libpython2.7-stdlib (= 2.7.15-4ubuntu4~18.04.2) but 2.7.17-1~18.04ubuntu1.6 is to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution)
