Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap can be installed from the command line on openSUSE Leap 42.3, Leap 15 and Tumbleweed.
You need first add the snappy repository from the terminal. Leap 15 users, for example, can do this with the following command:
