Debian 13 drops apt-key and software-properties-common, so the old tasks would fail after the upgrade. The key now lives in /etc/apt/keyrings (same fingerprint, 9DC8...CD88), the repo is a deb822 file whose release name follows the installed Debian, and the old .list file is removed. The apt tasks get a docker_apt tag so they can be deployed on their own. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
