Comment 15 for bug 1788722

Hi, I`m had same problem with upgrade Ubuntu 16.04 jewel -> luminous ceph-osd.

My controller version: 2.3.9

I´m get last version with command:

# charm pull ceph-osd

Only ceph-mon working for luminous after command:

# juju config ceph-mon source=cloud:xenial-pike

Upgrade ceph-osd not work after command:

# juju config ceph-osd source=cloud:xenial-pike

output log:

# tail -f /var/log/juju/unit-ceph-osd-3.log
