perl is already the newest version (5.26.0-8ubuntu1.1).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 libperl5.26 : Breaks: libperl5.26:i386 (!= 5.26.0-8ubuntu1) but 5.26.0-8ubuntu1.1 is to be installed
 libperl5.26:i386 : Breaks: libperl5.26 (!= 5.26.0-8ubuntu1.1) but 5.26.0-8ubuntu1 is to be installed
 perl : Depends: libperl5.26 (= 5.26.0-8ubuntu1.1) but 5.26.0-8ubuntu1 is to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

Found a FIX! Just need to move/backup the shared doc file that was causing the problem and all is right again.
