Hi, I am a new list member, and I was trying to follow up with the thread that John started concerning the keypair-add command failing. I, too, receive the same failure message: [root@myhostname ~(keystone_admin)]# nova keypair-add --pub_key cloud.key.pub cloudkey ERROR (BadRequest): Keypair data is invalid: failed to generate fingerprint (HTTP 400) (Request-ID: req-ac7961b3-b05e-40f8-a908-d8de7d4c36f1) I did see that installed the system using the packstack --allinone command, but I had forgotten to set the hostname. I have now done that, but I am unable to find any other place that might be causing the problem. I believe I have followed the entire thread on the rdo-list, and I am not seeing a resolution. Does anyone know if or how the problem was solved? Thank you very much for your time, Barbara
