      Description

      When trying to clone any Git repository with Jenkins 2.58, we ran into the following error:

      This is not the case with Jenkins 2.57; we suspect the updated SSH library in Jenkins 2.58 to be the cause. We run Jenkins as well as the Git server on standard CentOS 6.9, with non-modified SSH server settings, so the expection is that this should work (or the Jenkins Git Plugin help should describe which SSH cipher/algorithm settings need to be changed).
