package arno-iptables-firewall 1.9.2.h-1 failed to install/upgrade: il sottoprocesso vecchio script di post-installation ha restituito lo stato di errore 2

[Noob]

Every time I try to update/install some package related to "arno-iptables-firewall", I receive an error message.
I think I manually modified arno-iptables-firewall configuration.
How can I replace configuration file with a default configuration?

Thanks...and good luck!
