Ditto for the auditwheel project: https://travis-ci.org/pypa/auditwheel/jobs/643561176 shows errors like:
requests.exceptions.HTTPError: 404 Client Error: Not Found for url: http+docker://localhost/v1.35/containers/create
which are due to low disk space on /var/lib/docker according to this issue.
Running df -h in the build shows this volume at 99% full:
$ df -h
