On a fresh install of Kubuntu 18.04, ceph-volume will fail with the following errors:
sudo ceph-volume lvm create --bluestore --data /dev/sdc
Running command: ceph-authtool --gen-print-key
Running command: ceph --cluster ceph --name client.bootstrap-osd --keyring /var/lib/ceph/bootstrap-osd/ceph.keyring -i - osd new 994d129f-8c0a-4837-b25d-17425df64710

This can be fixed by running the ceph-create-keys command and then running ceph-volume again. This is most likely not a bug in ceph-volume, but more likely an improper ceph-deploy script.

I tend to agree with your conclusion (This is most likely not a bug in ceph-volume, but more likely an improper ceph-deploy script) - where are you sourcing ceph-deploy from? This is not something I use (and for reference a charm based deployment of ceph using ceph-volume works fine for me).
