Magnum recently added [1] a dependency on the marathon [2] python library which has not yet been packaged. We need to package marathon and add it as a dependency. [1]: https://review.openstack.org/#/c/333188/ [2]: https://pypi.python.org/pypi/marathon/0.8.6
Fixed in https://github.com/rdo-packages/magnum-distgit/commit/ed2dddfa6eba47c8217de669c50a59a05829178c
