Often times developers find themselves packaging their programs in many different package types, and get discouraged. It takes time to make all of these package files, and as a result, lots of programs don’t make it onto Linux. This is why the people at Ubuntu developed Snap packages. A snap is something that can be installed from the snap store, and inside the “snap” is everything the program is required to run.
This means that everything the app needs (libraries, binary files, image files, audio files and programs) are self contained and can run independent of the system. This ensures that no matter what, the program will run despite how outdated, or misconfigured the host system is. This Effectively makes it possible to install snaps on any Linux distribution, and makes it a “universal installer” that any developer, big or small, can pick up and even make their own snap store!
Note: Ubuntu users, as well as those using a Linux distribution based on Ubuntu will not need to install Snapd.
