Snap (software)

Snap is a package management system developed by Canonical for Linux operating systems. It is designed to provide a universal package format that works across different Linux distributions. Packages, referred to as "snaps," bundle an application and its dependencies together, creating a contained environment. This isolation aims to ensure that the application runs consistently regardless of the underlying system.

Snaps are self-contained and are mounted to the system using loop devices. They include the application binaries, libraries, configuration files, and other resources necessary for execution. This contrasts with traditional package management systems that rely on shared libraries and dependencies already installed on the system.

The Snap Store serves as a centralized repository where users can discover and install snaps. Developers can publish their applications to the Snap Store, making them available to a wide audience. Snaps can be updated automatically, offering users the latest features and security patches.

Snapd, the background service that manages snaps, handles installation, updates, and security. It provides an API for interacting with snaps and supports various features like sandboxing and confinement to enhance security.

Key features associated with Snap include:

• Universal Packaging: Works across different Linux distributions.
• Dependency Management: Bundles all dependencies within the snap.
• Isolation: Creates a contained environment for applications.
• Automatic Updates: Updates are managed automatically.
• Security: Employs sandboxing and confinement techniques.
• Snap Store: A centralized repository for discovering and installing snaps.
