While working on ceph images, I had a version in changelog that docker-pkg was unhappy with (18.2.2~wmf1, which is a legit Debian version, but docker-pkg doesn't like).
The error output (see typescript below) is pretty unclear - the naïve user (i.e. me!) will spend quite a lot of time confused by the localhost URLs and might miss the invalid reference format note that means "your package version is duff".
