Snap

Definition

A modern software packaging and deployment system developed by Canonical. Unlike APT, Snap packages are completely self-contained, including all their own dependencies, and run in an isolated sandbox.

Explain Like I'm New

Like a Docker container for desktop apps. Instead of an app relying on the messy shared files of your Operating System, it brings everything it needs bundled inside its own secure box.

Real World Example

You want to install Spotify. You type `sudo snap install spotify`. It downloads a massive file containing Spotify AND its specific version of Python and graphics libraries, ensuring it won't break your computer's files.

Common Use Cases

•Cross-distribution software installation
•Desktop applications

Question

More or less space?

Answer

Significantly MORE space. Because every Snap package bundles all of its own dependencies, you might end up having 5 different copies of Python installed on your hard drive.

Question

Why controversial?

Click to reveal answer

Answer

Because the backend server that hosts the Snap packages is proprietary and strictly controlled by one corporation (Canonical). It goes against the decentralized, open-source ethos of traditional Linux.
