Setup nut and netdata on Ubuntu

In this document, I will explain how to setup nut (Network UPS Tools) on Ubuntu 18.04 and 20.04.

It is basically the next chapter of my previous gist, Upgrade nut on Ubuntu 18.04.

I'll only document USB connected UPS and not the other supported connection modes.

The purpose of this document is to get you familiar with the concepts and command line tools involved with connecting to the internet using modern 4G LTE modems on both Debian/Ubuntu and OpenWRT.

This writeup is based on my experiences with the Sierra Wireless AirPrime MC7455 modem and a Calyx (Sprint) SIM card, but it should apply to most modern 4G LTE modems.

High level overview

These are the steps required:

Physically connect antennas

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

	Some more info can be found here https://help.ubuntu.com/community/ServerGUI. I assume you start with a clean install of Ubuntu Server 16.04 (some modifications may be needed for older versions of Ubuntu). Depending on your needs you can do these:

	Minimal GUI:

	sudo apt install xorg
	sudo apt install --no-install-recommends openbox
	Run the command startx and openbox will start (you can open a terminal there and run any application you want)
