'No package matching docker-ce' happens when Docker has no repo for the VM's release codename (common on non-LTS Ubuntu). Add docker_apt_codename (defaults to the detected release; override to e.g. noble on non-LTS) and refresh the apt cache right after adding the repo so index errors surface immediately instead of as a missing package.
