Paramiko unable to authenticate to older servers

Getting the following error when attempt to talk to on-prem raven and admin-pw in production.

Client: paramiko.ssh_exception.AuthenticationException: Authentication failed.

Server: userauth_pubkey: unsupported public key algorithm: rsa-sha2-512

See: https://github.com/paramiko/paramiko/issues/1961

Possibly pinning to 2.8.x or using disable_algorithms option.
