Documentation

Overview

Package snap provides an implementation of the syspkg manager interface for the snap package manager. It provides a Go (golang) API interface for interacting with the snap package manager. It allows you to query, install, and remove packages, and supports package managers like Apt, Snap, and Flatpak. This package is a wrapper around the snap command line tool.

Snap is a software deployment and package management system originally designed and built by Canonical, the company behind the Ubuntu Linux distribution. Snap packages are self-contained applications running in a sandbox with mediated access to the host system. Snap packages have no dependency on any libraries or packages installed on the host system, designed to work on any Linux distribution that has snap support installed. Snap packages are available from the Snap Store, an app store with an audience of millions, and also available from other sources, including the Ubuntu Store, the KDE Discover Store, and the elementary AppCenter.

This package is part of the syspkg library.
