I am using home-brew to install ELK stack with x-pack on my local OS X laptop. Earlier I was running 5.1.2 version without any issues. After upgrading ES, Kibana, LogStash to 5.2 version, X-Pack plugin installation on kibana is failing which is causing not to load kibana UI at http://localhost:5601/
