Hi @Jeni,

the Elasticsearch service from the Debian package runs as user "elasticsearch". The JAVA_HOME variable that you have shown is only set for the current user (which - I assume - is not "elasticsearch").

According to the Elasticsearch configuration docs, you can edit /etc/default/elasticsearch and set JAVA_HOME there for Elasticsearch. Can you please do this and try to start Elasticsearch again via systemd?

Hi @Jeni,

can you please check the logs in /var/log/elasticsearch? Wild guess: You will see one or more failing bootstrap checks there so you should follow the section important system configuration in the docs.
