Elasticsearch failing to run

Question

I have elasticsearch in a Ubuntu 18.04 VM that worked the first time I installed it. But after a reboot, it can't start anymore. The Java version is:

openjdk version "1.8.0_252"

the status of the elasticsearch service is as follows:

systemctl status elasticsearch
● elasticsearch.service - Elasticsearch
   Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; enabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since Thu 2020-05-07 21:46:51 EDT; 8min ago

I have adjusted the /etc/elasticsearch/jvm.options file to 512m, 1g and 4g but still can't work.

journalctl -u elasticsearch shows the following output:

I see the warning "Permission denied, but I'm a superuser and the folder is owned by root.

Any idea on what might be wrong?

Thank you.

ok, I re-installed elasticsearch and this time the system works well after several reboots. Sorry, no RFO, maybe some misconfiguration during the installation process.
