I'm trying to do a Scap release, and as part of that running cumin on deployment-deploy01, but this fails.
deployment-imagescaler01.deployment-prep.eqiad.wmflabs has a host key not in my SSH known hosts file. I don't know where to find the new key reliably. Also, why has it changed? This worked when I did the previous Scap release a few weeks ago.
Am I just doing something wrong?
