Jclouds will try to connect to the node via SSH to install the public key. That error appears because jclouds does not know the credentials to use (has the node been created with jclouds?).
You will have to pass a RunScriptOptions object as a third parameter to the "runScript" method, with the "overrideLogin*" options set. Those options should tell jclouds how to login to the node with the existing user to install the new key.
