Elasticsearch won't start in ubuntu 18.04.4 LTS

Question

So i tried to start elasticsearch with this command:

systemctl start elasticsearch.service

and i got this error :

Job for elasticsearch.service failed because a fatal signal was delivered to the control process.
See "systemctl status elasticsearch.service" and "journalctl -xe" for details.

this is "journalctl -xe" output :

The issue was resolved by using the tarball installation by following the official https://www.elastic.co/guide/en/elasticsearch/reference/current/targz.html installation instructions.

Please make sure the user which you are using to run the elasticsearch process has write access to the filesystem where the elasticsearch process is writing. Please see the comments in the question section for more info and error related to this.
