Hello,  
I am installing ELK following the instructions on this website. [https://www.digitalocean.com/community/tutorials/how-to-install-elasticsearch-logstash-and-kibana-elastic-stack-on-ubuntu-18-04](https://www.digitalocean.com/community/tutorials/how-to-install-elasticsearch-logstash-and-kibana-elastic-stack-on-ubuntu-18-04).  
For the command  
`sudo filebeat setup --template -E output.logstash.enabled=false -E 'output.elasticsearch.hosts=["localhost:9200"]'`  
, I get this response : `'Couldn't connect to any of the configured Elasticsearch hosts. Errors: [Error connection to Elasticsearch http://localhost:9200: Connection marked as failed because the onConnect callback failed: invalid license found, requires a basic or a valid trial license and received Open source]'`

Do you know what's happening ? Do i need a license for installing ELK ?

Thanks in advance.

Eddie

You need to install the default package of elasticsearch not the oss one.
