Note that all of the other gnocchi-* packages other than gnocchi-api
(gnocchi-metricd and gnocchi-statsd) support python2. You just need to
install python-gnocchi before installing them. If you don't do that they'll
default to python3-gnocchi.

I agree it should be coordinated. I'm going to test gnocchi-api support for
python2 as an alternative (would behave similar to how the above packages
work). It's an easy fix. Stay tuned to the bug that was linked earlier.

Yes, the the same package source is used for bionic and queens.

Thanks,
