How To Fix nft: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu nft is provided by nftables package.

nftables is:

This software provides an in-kernel packet classification framework that is based on a network-specific Virtual Machine (VM) and the nft userspace command line tool. The nftables framework reuses the existing Netfilter subsystems such as the existing hook infrastructure, the connection tracking system, NAT, userspace queueing and logging subsystem.

nftables replaces the old popular iptables, ip6tables, arptables and ebtables.

Netfilter software and nftables in particular are used in applications such as Internet connection sharing, firewalls, IP accounting, transparent proxying, advanced routing and traffic control.

A Linux kernel >= 3.13 is required. However, >= 4.14 is recommended.
