Please allow PyPy to work on Xenial


My builds fail since I added dist: xenial, since PyPy appears unsupported there. Excerpt from a job log:

pypy is not installed; attempting download
Downloading archive:
$ curl -sSf -o pypy.tar.bz2 ${archive_url}
curl: (22) The requested URL returned error: 403 Forbidden
Unable to download pypy archive. The archive may not exist. Please consider a different version.


It should work if you specifically ask for the latest version of PyPy, for example:

   - python: "pypy2.7-6.0"
   - python: "pypy3.5-6.0"

Dbus-python Dependency (any version) does not work
