Your options while staying on Xenial are only to Nautilus.
In the below chart, X is provided by the Ceph repos, U denotes from Ubuntu 
repos.

luminus
mimic
nautilus
octopus

XU

Octopus is only supported on bionic and focal.
Xenial has 8 months of support left before ESM is required, so if sticking with 
ceph, you may want to look towards at least bionic as a path to Octopus.

Hope this helps.
