Description

During setup on a fresh Debian Trixie server, I noticed that Docker was not installed correctly because the Docker APT repository could not be set up due to the missing GPG utility.

Log from failed installation of version 1.13.0:

This contribution is adding a gpg utility to the install script, which results in a successful installation of docker

How to test?

Run the install on Debian/Ubuntu which doesn't already have docker and gpg installed.
