Hi, I have installed ceph on Ubuntu Focal Fossa using the ubuntu repo, instead of ceph-deploy (as ceph-deploy install does not work for Focal Fossa yet) install I used: sudo apt-get install -y ceph ceph-mds radosgw ceph-mgr-dashboard The rest of the setup was the same as the quickstart on ceph.io < http://ceph.io/> with ceph-deploy. It installed ceph version 15.2.1 (octopus). If I do a 'ceph -s' I get the warning: health: HEALTH_WARN 2 mgr modules have failed dependencies If I run 'ceph mgr module ls', for enabled and active modules I get: "always_on_modules": [ "balancer", "crash", "devicehealth", "orchestrator", "osd_support", "pg_autoscaler", "progress", "rbd_support", "status", "telemetry", "volumes" ], "enabled_modules": [ "iostat", "restful” Then when I run 'ceph mgr module enable dashboard’ I get the error: Error ENOENT: module 'dashboard' reports that it cannot run on the active manager daemon: No module named 'yaml' (pass --force to force enablement) I have tried searching, and searching with apt but cannot find any ‘yaml’ package that might be used by ceph.
