Distributor ID:    Ubuntu
Description:    Ubuntu 22.04.3 LTS
Release:    22.04
Codename:    jammy

Step 2: Use curl command for transferring data with URLs, to import the Elasticsearch public GPG key into APT.

root@linuxhelp:~# curl -fsSL https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo gpg --dearmor -o /usr/share/keyrings/elastic.gpg

Step 3: Add the Elastic source list to the sources.list.d directory, where apt will search for new sources.

root@linuxhelp:~# echo "deb [signed-by=/usr/share/keyrings/elastic.gpg] https://artifacts.elastic.co/packages/7.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-7.x.list
deb [signed-by=/usr/share/keyrings/elastic.gpg] https://artifacts.elastic.co/packages/7.x/apt stable main

Step 4: Update package lists by using the following command

root@linuxhelp:~# apt update
