References:
Detailed instructions for installing Elastic Search in Ubuntu can be found here:
Installing Elasticsearch | Elasticsearch Guide [8.3] | Elastic
The following instructions follow the instructions available at the following link which documents installing with the Debian package:
Install Elasticsearch with Debian Package | Elasticsearch Guide [8.3] | Elastic
Instructions:
The most common install is to manually download the installation files that are for Debian and install it.
Download and add the Elastic Search key:
wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
Now download the needed installation files
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.0.0-amd64.deb
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.0.0-amd64.deb.sha512
shasum -a 512 -c elasticsearch-8.0.0-amd64.deb.sha512
sudo dpkg -i elasticsearch-8.0.0-amd64.deb
Note: If previous command gives you an error then attempt to run
sudo rm /var/lib/dpkg/lock-frontend
Copy the entire Security autoconfiguration information in to a text file called README.txt
Example:

Now enable the elasticsearch service and set it to run automatically for us

sudo systemctl daemon-reload
sudo systemctl enable elasticsearch.service
sudo systemctl start elasticsearch.service
✔️Ensure elastic is running by navigating to https://localhost:9200 in a browser or by running the command:

NOte: use journalctl -u elasticsearch.service if you need to see the status.

default username will be: elastic

wget -qO- https://saltminer:9200/

this needs to be edited

FYI on File locations:

The following is just an FYI, there is no more work to be done in this section.

The default location for the configuration files will be in: /etc/elasticsearch

The Debian package places config files, logs, and the data directory in the appropriate locations for a Debian-based system:
