I know this is a very old topic, however I thought I'd add to it in case
the original author will still get updates and for anyone else running into
issues who comes across this thread.
For myself, the issue was not having the public key (that was generated on
the server you're trying to connect to), in the authorized_keys file.
I'll explain a bit further to provide context. Our Jenkins ID didn't have
access to publish artifacts out to the folder we needed to push them to
after doing the build. In order to get around it, we were trying to setup
a pipeline script and use sshagent to ssh back into the same server Jenkins
is running on but with a different user ID.
In order to accomplish this, I logged onto the Jenkins server and navigated
to the .ssh directory for the user that had the proper folder access. From
that location, I generated a new keypair, created the "authorized_keys"
file (directly within the .ssh folder) and then added the newly generated
public key into it. That was the piece we were missing that was preventing
us from properly connecting. After that, we created the credential in
Jenkins with the private key. From there, we were able to use that user in
our ssh command and it connected and executed commands properly.
