Comment 79 for bug 2055114

I tried this package, https://launchpad.net/ubuntu/+source/fail2ban (proposed) on a server without fail2ban

I missed something ? I guess this is related to https://github.com/fail2ban/fail2ban/issues/3754
But if some dependencies are missed i should have some warning messages from package, no ?

dpkg -i fail2ban_1.0.2-3ubuntu0.1_all.deb
