Public bug reported:
High-traffic ticket on stack-overflow:
https://askubuntu.com/questions/1249452/iptables-not-working-on-ubuntu-
server-raspberry-pi-4-module-ip-tables-not-fo
My own Pi4B is also failing, this prevents me from installing docker with the
following errors:
Jan 3 02:09:34 localhost dockerd[2103]: failed to start daemon: Error
initializing network controller: error obtaining controller instance: failed to
create NAT chain DOCKER: iptables failed: iptables -t nat -N DOCKER: iptables
v1.8.4 (legacy): can't initialize iptables table `nat': Table does not exist
(do you need to insmod?)
iptables is already installed, removing/re-adding does not help:
apt install iptables
Reading package lists... Done
Building dependency tree
Reading state information... Done
iptables is already the newest version (1.8.4-3ubuntu2).
and running iptables itself fails:
iptables -S
iptables v1.8.4 (legacy): can't initialize iptables table `filter': Table does
not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
Also the module is shown as loaded already in the kernel:
lsmod

This affects everyone who runs iptables & docker on the recent ubuntu-raspi
image, please help? Additional system info below:
Description: Ubuntu 20.04.5 LTS
Release: 20.04
