Now i have installed on a Ubuntu server 20.04 i got this error : /opt/Siren/siren-platform-easy-start-10.5.1-linux-x86\_64/elasticsearch$ sudo ./bin/elasticsearch OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.

And if you get `AccessDeniedException` on any config file then take ownership of it via chown. [More info](https://github.com/elastic/elasticsearch/blob/2774cd6938bb5dff3fa31c2dd9d2b8c592ab1222/docs/reference/scripting/security.asciidoc#do-not-run-as-root) on why you should not run elasticsearch as root.
