The SSH keys are set-up via https://github.com/akraino-edge-stack/icn/blob/master/deploy/kud/kud_bm_launch.sh#L24-L35, that sets them up in $HOME/.ssh. But the problem is that Ansible later tries to connect as `root@IPaddress` but instead of picking the SSH keys from the user's home ($HOME), it looks for them in /root (and fails because it cannot find them).

Workaround: "sudo cp -r ~/.ssh/* /root/" and then rerun "sudo make install"
