Hello, I am am new to all elastic , so there might me a straight solution I simply don't know I installed elastic and kibana on a ubuntu 18.04. when I start Kibana I find this FATAL Error: [elasticsearch.url]: definition for this key is missing in /var/log/kibana/kibana.stderr in /etc/kibana/kibana.yml I have this server.port: 5601 server.host: "192.168.56.51" elasticsearch.url: "[http://localhost:9201](http://localhost:9201)" logging.verbose: True when I do a wget [http://localhost:9201](http://localhost:9201) on the machine I get the expected index.html from elastic there is not more in the logs. Any reason why kibana would complain about the url ? ---

What version of Kibana are you using? `elasticsearc.url` has been added as an option in kibana.yml only recently. ---

as it doesnt start I can't tell for sure. It should be latest of kibana\_version: "6.x" I installed it through this [ansible-role-kibana](https://github.com/geerlingguy/ansible-role-kibana) ---

thanks for the reply ! Actually it looks like the ubuntu packages are simply crap. I reinstalled everything from the tar files and everything works fine. I only changes the server host thing for kibana I am now on 7.2.1 ---
