focal cloud image on kvm does not have ip_tables kernel module

[Amitava Shee]

$ sudo iptables -L
modprobe: FATAL: Module ip_tables not found in directory /lib/modules/5.4.0-84-generic
iptables v1.6.1: can't initialize iptables table `filter': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

No ip_tables.ko

Hello, can you please look for ip_tables.ko in /lib/modules/*/kernel/net/ipv4/netfilter/ip_tables.ko ? Which linux-modules-* package and which linux-image-* packages do you have installed?

Thanks
