I'm having issues trying to start Elastic Search after installation, and I'm not sure how to get around it, nor can I find any similar topics with solutions online.
When I run systemctl start elasticsearch
, I get the error that the service cannot be started, when running journalctl -xe
, this is the error that is outputted:

Seems like a permission issue, but I'm not sure how to get around it, does anyone have any ideas? I'm using Ubuntu 20.04.
