Hi Goetz, I've done the same, and went to Octopus and to Ubuntu. It worked like a charm and with pip, you can get the pecan library working. I think I did it with this: yum -y install python36-six.noarch python36-PyYAML.x86_64 pip3 install pecan werkzeug cherrypy Worked very well, until we got hit by this bug: https://tracker.ceph.com/issues/53729#note-65 Nautilus seem not to have tooling to detect it, and the fix is not backported to octopus. And because our clusters started to act badly after the octopus upgrade, and we fast forwarded to pacific (untested emergency cluster upgrades are okayish but ugly :D ). And because of the bug, we went another route with the last cluster. I reinstalled all hosts with ubuntu 18.04, then update straight to pacific, and then upgrade to ubuntu 20.04. Hope that helped.
