[SOLVED] How apt-get know how to download ElasticSearch?

Issue

I'm following the instructions to install Elasticsearch from apt-get and I'd like to know how it is actually working.

1. I've added a file elastic-7.x.list in directory /etc/apt/sources.list.d with the following content:

deb https://artifacts.elastic.co/packages/7.x/apt stable main

When I run sudo apt-get update I guess the apt-get uses the entry in the elastic-7.x.list file to get information about packages in this remote repository.

But when I go to https://artifacts.elastic.co/packages/7.x/apt I get a Not Found from my browser.

When I do this with a link with a ubuntu default repository (e.g http://security.ubuntu.com/ubuntu) I can see the directories:

I've found the http://security.ubuntu.com/ubuntu link in /etc/apt/sources.list file.

How the apt-get actually works to get information from the link https://artifacts.elastic.co/packages/7.x/apt?

Solution

The apt repository can be browsable, but it doesn't have to be. The Elastic one isn't — IMO because it doesn't generate the index files. Those aren't needed by apt since it can pick up the right resources without the index files in between.

If you want a browsable catalog, use https://www.elastic.co/downloads/past-releases.
