Hi, you probably need to update SSH plugins:
https://plugins.jenkins.io/publish-over-ssh -> 1.14 has a newer Jsch that provides the new algorithms. For ssh plugin (https://plugins.jenkins.io/ssh), you need to get an update on https://github.com/jenkinsci/jsch-plugin/ to 0.1.54.2 mot probably. Björn Am Donnerstag, 17.
