GnuPG 2.2.1 Build Instructions

Below are my build instructions for GnuPG 2.2.1, released on September 19th, 2017. These instructions are built for a Ubuntu 16.04 LTS.

If you prefer, you may use the below install script to install GnuPG 2.2.1 by running the following commands:

curl -OL "https://gist.github.com/romen/b7bac24d679d91acabb27bfcdabbee01/raw/b93b7b00910db67c2c3332606792679802abbb32/install-gnupg22.sh" && bash ./install-gnupg22.sh

Install the needed dependencies

apt-get -y install libgnutls-dev bzip2 make gettext texinfo gnutls-bin build-essential libbz2-dev zlib1g-dev libncurses5-dev libsqlite3-dev libldap2-dev || apt-get -y install libgnutls28-dev bzip2 make gettext texinfo gnutls-bin build-essential libbz2-dev zlib1g-dev libncurses5-dev libsqlite3-dev libldap2-dev

apt-get -y install checkinstall

# Only if you want to compile pinentry with support for gnome3 or gtk2 UI
apt-get -y install libgcr-3-dev libgtk2.0-dev

Setup the build

Note: To clean up from the older GnuPG 2.1.x builds, you probably want to delete /var/src/gnupg21 entirely.

mkdir -p /var/src/gnupg22 && cd /var/src/gnupg22
