Answer 1

Try to connect first simply using ssh only, then post adding it to known hosts try sshpass, etc. as required.

In my case, I had done a clean new install of linux distro and installed sshpass and it started giving errors, they all went away as soon as I connected first via ssh and added the remote server's IP in the known hosts.

Answer 2

I solved same problem with this command:

rsync --rsh="/usr/bin/sshpass -p "password" ssh -o StrictHostKeyChecking=no -l root" /source/file/path [email protected]:/destination/file/path

Note: Be sure about each side has sshpass installation before usage.

Answer 3

In my case I was able to just 'ssh user@host' first and it offered to auto-generate the key for me which was then saved for subsequent sessions.
