Hi everyone, This has come up several times before, but we need to make a final decision. Alfredo has a PR prepared that drops Python 2 support entirely in master, which will mean nautilus is Python 3 only. All of our distro targets (el7, bionic, xenial) include python 3, so that isn't an issue. However, it also means that users of python-rados, python-rbd, and python-cephfs will need to be using python 3.
I'm not sure dropping Python 2 support in Nautilus is reasonable... simply because Python 3 support isn't quite stable in Mimic yet - I just filed https://tracker.ceph.com/issues/37963 for ceph-volume being broken with Python 3 and dm-crypt :-)
I think there needs to be a release that supports both equally well to give people time to safely migrate over. Might be worth doing some tree-wide reviews (like that division thing) to hopefully squash more lurking Python 3 bugs.
(just my 2c - maybe I got unlucky and otherwise things work well enough for everyone else in Py3; I'm certainly happy to get rid of Py2 ASAP).
