GnuPG 2.2.x Build Instructions

Below are my build/compile instructions for GnuPG 2.2.27, released on Monday, January 11, 2021. These instructions were tested on a working Kubuntu 20.10 "The Groovy Gorilla" desktop environment but should be applicable to all Debian-derivative GNU/Linux distributions since Ubuntu 18.04 LTS "Bionic Beaver." (Go Beavers!)

If you prefer, you may use the install script below to automate the process and install GnuPG 2.2.27 with the following command on your computer's terminal:

curl -L https://mello.link/gnupg2227 | sudo -H bash

This works for http upstream servers, but also for other protocols, that can be secured with TLS.

prerequisites

• at least nginx 1.15.9 to use variables in ssl_certificate and ssl_certificate_key.
• check nginx -V for the following:

  ...
  TLS SNI support enabled
