I’ve just reinstalled Ubuntu and docker my four nodes, but when running cephadm, I get the message that it pulls an age-old version (15) of the Ceph container and then exits with an error:
Pulling container image quay.io/ceph/ceph:v15...
Non-zero exit code 1 from /usr/bin/docker pull quay.io/ceph/ceph:v15
