Hi,
what's your ceph version? You probably don't have host labels set
(check 'ceph orch host ls') and cephadm tries to copy a keyring to
admin hosts with the _admin label [1]. Also check out how to put
keyrings under management [2], I haven't dealt with that too intense
yet. But basically it states:
Starting from versions 16.2.10 (Pacific) and 17.2.1
(Quincy), in
addition to the default location /etc/ceph/ cephadm also stores
config and keyring files in the /var/lib/ceph/<fsid>/config
directory. It is usually a good idea to store a copy of the config
and client.admin keyring on any host used to administer the cluster
via the CLI. By default, cephadm does this for any nodes that have
the _admin label (which normally includes the bootstrap host).
Regards,
Eugen

"No matching hosts for label _admin" means that there is no host which
has the label _admin.
The label _admin is a special label which instructs the orchestrator to
keep /etc/ceph/ceph.conf and /etc/ceph/ceph.client.admin.keyring on such
labeled hosts up to date.
You could just label one of the cluster hosts with _admin:
ceph orch host label add hostname _admin
