We're used a local registry (docker registry), but needed to switch to Harbor. The old registry needed credentials and was working fine. I used "sudo cephadm -v registry-login --registry-json login" to login to the new registry. login is the json with the credentials. When starting the upgrade, I get the following error: "UPGRADE_FAILED_PULL: Upgrade: failed to pull target image". But using "sudo cephadm --image <url> pull" works fine. $ sudo cephadm --image harbor.url/project/ceph/ceph:v18.2.6-20250417 pull Pulling container image harbor.url/project/ceph/ceph:v18.2.6-20250417... { "ceph_version": "ceph version 18.2.6 (ff498e17d264a1a4d588c361cbce9cc65afa2327) reef (stable)", "image_id": "d4baa6a728fa46bda2d58db9f458847bde23ca99135c6c9bb025a9d50fb9f011", "repo_digests": [ "harbor.url/project/ceph/ceph@sha256:848ef15fd4bb29a42d1063aba7b2543432ecec78afe35e7b64cc91f9748de551" ] } I also tried updating the config, didn't help either. ceph config-key set mgr/cephadm/registry_url ceph config-key set mgr/cephadm/registry_username ceph config-key set mgr/cephadm/registry_password So what's wrong? Currently using 18.2.4.
