Jenkins [Jenkins 2.361.1] hosted on Ubuntu 22 in AWS is able to send files over SSH to Ubuntu 18 and 20 using pem files. But Jenkins hosted on Ubuntu 22 is unable to send files over SSH to Ubuntu 22. Whenyou ssh into Jenkins server and try to manually do ssh or scp it works but from Jenkins Post Build action task it fails.

Starting with Ubuntu 22 "ssh client in Ubuntu 22.04 with the RSA public-private key pair is considered not safe any more." I referred to https://askubuntu.com/questions/1409105/ubuntu-22-04-ssh-the-rsa-key-isnt-working-since-upgrading-from-20-04 and added PubkeyAcceptedKeyTypes +ssh-rsa to /etc/ssh/sshd_config and restarted sshd service using "sudo systemctl restart sshd" This resolved the publish over ssh issue.
