<https://stackoverflow.com/posts/74046155/timeline> I followed the instruction in ceph doc <https://docs.ceph.com/en/latest/cephadm/install/> But, to summarize, this is why I did. Please note that this error occurs with the previous release, such as Pacific and Nautilus. curl --silent --remote-name --location https://github.com/ceph/ceph/raw/quincy/src/cephadm/cephadm chmod +x cephadm ./cephadm add-repo --release quincy Here is the error, I copied the whole thing. Look at the last line. Installing repo GPG key from https://download.ceph.com/keys/release.gpg... Installing repo file at /etc/apt/sources.list.d/ceph.list... Updating package list...
