Why is Ubuntu using snaps?

Snap is a software package and deployment system that uses self-contained packages called snaps to deliver software to users. Snaps pack all the dependencies a program requires in a single package. In this way, the app is system-agnostic, meaning that it can natively run on any Linux distribution that supports Snap.

How do you make a snap package?

Creating a snap

1. Create a checklist. Better understand your snap’s requirements.
2. Create a snapcraft.yaml file. Describes your snap’s build dependencies and run-time requirements.
3. Add interfaces to your snap. Share system resources with your snap, and from one snap to another.
4. Publish and share.
