GnuPG 2.2.x Build Instructions

Below are my build instructions for GnuPG 2.2.10, released on August 30th, 2018. These instructions are built for a headless Ubuntu 18.04 LTS server (and have also been tested on Ubuntu 14.04/16.04).

If you prefer, you may use the below install script to install GnuPG 2.2.x by running the following commands:

curl -OL "https://gist.githubusercontent.com/vt0r/a2f8c0bcb1400131ff51/raw/e0d2011d7b89bfe5b83c3f29f21949fb21354dd9/install-gnupg22.sh" && sudo -H 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

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

@okkymabruri , why did you remove the 'gpg --verify' lines from the code?
Or, rather, why would you install unverified software on your system?

Script install latest GNUPG in Ubuntu 20.10
(Thanks to @loizoskounios, I've modified your script and work)

okkymabruri · 2020-12-26T16:34:04Z

@NoSubstitute, thanks, I missed it

bachmanity1 · 2022-12-29T09:36:09Z

I have gpg 2.0.22 installed on my machine after running this script everything seems to work and message Complete!!! is printed however I'm not able to find gpg 2.2.9 anywhere in my filesystem. (I have checked /usr/bin and /usr/local/bin). Where can I find installed binaries?

NoSubstitute · 2022-12-30T13:30:06Z

@bachmanity1 - oh, 2.2.9 is really old.

Here is my most recent script, which includes grabbing a current version of Scute directly from git.

Afterwards I also check for running gpg daemons and kill them before trying a gpg command.

ps aux | grep gpg
killall gpg-agent

If you get a a warning about gpg-agent being "older than", then you may have gpg installed from your distro's repo too, and not only a compiled version. A reboot will probably fix that, or uninstall the system version.
