Bug #18382
Updated by Nathan Cutler over 7 years ago
In hammer 0.94.10 integration testing, the Xenial build succeeds - see https://shaman.ceph.com/builds/ceph/wip-hammer-backports/c4bf69da75feb8eb7a69a9bd73ec76a4ae280edf/default/10205/ - but cannot be installed.

As a result, all tests involving a Ubuntu Xenial target machine fail.
Since Trusty works, the workaround is to force teuthology to use that by adding <code>qa/distros/all/ubuntu_14.04.yaml</code> to the command line. Thanks, Loic, for pointing this out.
