I’ve run into the same dependency errors on an existing ceph installation sometime in April or May (I think – it was before 9.6 was released). The reason for the error is that packages in ceph’s repositories are built against CentOS Stream which (in this case) is a little more than just ahead of proper enterprise linux releases.

I think I saw somewhere that the required openssl should be in RHEL/Rocky 9.7.

I don’t have the link handy, but a while back I found some reference to this issue on a ceph forum or mailing list. My impression was that there was no real willingness to address this as a worthwhile problem – the general attitude was that everyone should just use container-based deployments.

But does this not prevent the use of any ceph comands to do any sort of configuring on the OSD for example?

By manually installing podman I am able to add the host to the cluster using ceph gui, but I am not able to run any ceph commands on that host to configure anything.

I believe cephadmis one of the container-centered tools that the ceph team seems to be interested in supporting an promoting. So hopefully your bug report should get some traction and not just a recommendation to run cephadm itself as a container.
