package fail2ban 0.9.3-1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

[Justin Middagh]

It does appear similar to both of those errors but I am using Ubuntu Server 16.04.3 LTS.
I just cannot get fail2ban up and running to matter what I do, hopefully you guys can help me out.
