Hi,
I think there's something else wrong with your setup, I could
bootstrap a cluster without an issue with ed keys:
ceph:~ # ssh-keygen -t ed25519
Generating public/private ed25519 key pair.
ceph:~ # cephadm --image quay.io/ceph/ceph:v18.2.2 bootstrap --mon-ip
[IP] [some more options] --ssh-private-key .ssh/id_ed25519
--ssh-public-key .ssh/id_ed25519.pub
...
Using provided ssh keys...
Adding key to root@localhost authorized_keys...
Adding host ceph...
...
Bootstrap complete.
ceph:~ # ceph cephadm get-pub-key
ssh-ed25519 AAAAC... root@ceph
Regards,
Eugen
