Apparently, I fixed it. In order for this process to complete successfully, one must create a subdirectory under home for the (non-existent) root user. Then create a subdirectory under ../home/root/ named .ssh. Then copy the key files from ../home/administrator/.ssh/* into the ../home/root/.ssh/ directory.
Then scp seems to work fine without requiring a password. Tried it on two machines and it works. Thanks for your help anyway. Blaine R.
