How to install PHP 7.2 on Ubuntu?

Question

PHP

The system was just installed by Ubuntu 16.04 php -v command not found means everything is ok.
Further, for example:

sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get install php7.2-cli

Mistake:

Reading package lists... Done
Building dependency tree... Done
E: Unable to locate package php7.2-cli
E: Couldn't find any package by glob 'php7.2-cli'
E: Couldn't find any package by regex 'php7.2-cli'

Ok, php 7 seems to be in the official turnips, I do: sudo apt show php
Errors:

N: Unable to locate package php
N: Unable to locate package php
E: No packages found

The same result when apt install php
I somehow use the package manager incorrectly or what should I do first? Turnips update?

A very good article on Digital Oceans fits Ubuntu exactly. I put the first time in my life on a remote server without a graph. shells. There's an article on how to install a LAMP stack + Wordpress / Also PHP and PHP modules my Admin
Googled ...... Do it very slowly and carefully. better do it in 4 hours but the first time.
