This repository contains the code for snapd, which is the background service responsible for managing and maintaining the installed snap packages. Snaps are versatile application packages designed for desktop, cloud, and IoT environments, featuring automatic updates. They are user-friendly, secure, compatible across different platforms, and do not require additional dependencies, making them popular on millions of Linux systems daily. In addition to various service and management capabilities, snapd offers the snap command for installing and removing snaps while facilitating interaction with the broader snap ecosystem. It also enforces confinement policies that keep snaps isolated from the base system and from each other, and it manages the interfaces that allow snaps to utilize specific system resources beyond their confinement. For those interested in installing applications like Spotify or Visual Studio Code, the Snap Store is a great place to explore. Furthermore, if you're keen on creating your own snaps, we recommend starting with our comprehensive documentation on how to build a snap. This documentation will guide you through the essential steps for developing and packaging your apps effectively.
