Put simply, borg was not in your clientside ~/.ssh/known_hosts.  When 
you said yes, it was added.  There's nothing to troubleshoot about that, 
from now on ssh connects to borg will be checked against the signature 
stored now in your known_hosts, silently unless borg's signature changes 
(because it is another machine trying to fake you out, or because you 
reinstalled the OS on borg, etc).

When you run ssh-agent, it prints out some shell commands to set 
environment vars.  You need to make sure that the environment you run 
ssh from has those vars in it, otherwise ssh cannot communicate with 
ssh-agent.
