You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 perl : Depends: perl-base (= 5.24.1-3+deb9u5) but 5.24.1-3+deb9u6 is to be installed
        Depends: libperl5.24 (= 5.24.1-3+deb9u5) but 5.24.1-3+deb9u6 is to be installed
        Recommends: rename but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
