Packages are coming from here: https://2.chacra.ceph.com/r/ceph/wip-hammer-backports/c4bf69da75feb8eb7a69a9bd73ec76a4ae280edf/ubuntu/xenial/flavors/default/pool/main/c/ceph/

The python-rados, etc. packages are present in that repo, yet the "apt-get install" command is failing. I don't understand why it doesn't automatically pull in the dependencies.

If I'm understanding the output here correctly, the dependency version numbers aren't set properly.

Description: common utilities to mount and interact with a ceph storage cluster
 Ceph is a massively scalable, open-source, distributed
 storage system that runs on commodity hardware and delivers object,
 block and file system storage.  This is a collection
 of common tools that allow one to interact with and administer a Ceph cluster.

@David: This may not be worth your time. Hammer is nearing EOL, is not supported on Xenial, and I have found a workaround for the 0.94.10 integration testing.
