I have a 2 node cluster with a QDevice running on Ubuntu 22.04 on a repurposed desktop PC. I want to change this to a Raspberry Pi 2 which has Ubuntu 22.04 installed.

I have removed the existing QDevice from the cluster but when I try to add the new one (which has a different IP address), I'm getting an error.

Code:
root@pve2:~# pvecm qdevice setup 10.20.30.2
/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub"
/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
root@10.20.30.2's password:

Number of key(s) added: 1

Now try logging into the machine, with: "ssh -i /root/.ssh/id_rsa 'root@10.20.30.2'"
and check to make sure that only the key(s) you wanted were added.

The Pi is newly installed and has PermitRootLogin yes in the sshd config. I can ssh into the Pi using root credentials both from my machine and the pve node.
