Installing iptables-persistent on ubuntu without manual input

iptables-persistent no input

echo iptables-persistent iptables-persistent/autosave_v4 boolean true | sudo debconf-set-selections
echo iptables-persistent iptables-persistent/autosave_v4 boolean true | sudo debconf-set-selections

sudo apt-get -y install iptables-persistent

both lines are v4! i think one have to be v6? :)

Thank you 👍

Thank you !

@5ilv4n0: yes, correct. To any wayward web search folks, here's an updated version:

echo iptables-persistent iptables-persistent/autosave_v4 boolean true | sudo debconf-set-selections
echo iptables-persistent iptables-persistent/autosave_v6 boolean true | sudo debconf-set-selections

sudo apt-get -y install iptables-persistent

You can verify these fields by installing debconf-utils and searching for iptables values:

sudo apt install debconf-utils

sudo debconf-get-selections | grep iptables

Thank you +1

Thank you ! Very useful for bash script !

Thanks. Here's a variation.

sudo debconf-set-selections <<EOF
iptables-persistent iptables-persistent/autosave_v4 boolean true
iptables-persistent iptables-persistent/autosave_v6 boolean true
EOF
