The Ubuntu equivalent to the Debian dists/stable/Release file is typically found at:

http://archive.ubuntu.com/ubuntu/dists/<release>/Release

Explanation:

• Debian's dists/stable/Release: This file contains metadata about the Debian stable release, including package lists, hashes, and repository information.
• Ubuntu's equivalent: Ubuntu follows a similar structure but organizes its repositories by release codename (e.g., jammy, noble, focal). The Release file for a specific Ubuntu version is located under its respective dists/<release> directory.

Example:

For Ubuntu 24.04 LTS (Noble Numbat), the equivalent URL would be:

http://archive.ubuntu.com/ubuntu/dists/noble/Release

For Ubuntu 22.04 LTS (Jammy Jellyfish), it would be:

http://archive.ubuntu.com/ubuntu/dists/jammy/Release

Key Differences:

• Debian uses stable, testing, and unstable as floating release names.
• Ubuntu uses fixed release codenames (e.g., noble, jammy) for each version.
