how strange, as the code from a9219384 explicitly tests this:

            (status, output) = run(["dpkg-query", "-f", "${Version}\n", "-W", "apt"], ignore_errors=True)
            apt_can_install_debs = LooseVersion(output.strip()) >= LooseVersion("1.1")

ack. (atm only present in git branch develop…)
