I followed [these](https://discuss.elastic.co/t/enterprise-search-installation-gives-api-key-error/283645) steps for the installation.

Copying and pasting [these lines](https://discuss.elastic.co/t/enterprise-search-installation-gives-api-key-error/283645/print) into Elasticsearch, kibana and enterprise-search yaml files

Changed the permissions of var/log/enterprise-search folder and contents (see screenshot below)

And everything started fine.

Then, I switched-off and then on and got this error message:

Any suggestions?

d@vmm:~$ sudo systemctl start Elasticsearch.service  
Job for Elasticsearch.service failed because the control process exited with error code.  
See "systemctl status Elasticsearch.service" and "journalctl -xeu Elasticsearch.service" for details.

Can you please check the underlying Elasticsearch logs, usually `/var/log/elasticsearch`.
