ERROR: Unexpected error in launching a agent. This is probably a bug in Jenkins.ERROR: Unexpected error in launching a agent.

 Plugins were updated three days ago and a restart of 2.184 went fine. Now I just updated to 2.185 and got the quoted "Unknown server host key algorithm 'ssh-ed25519'" messages with all agents (Linux and MacOS) offline. Probably something related to the recent 'trilead' changes?
