Snaps are containerised software packages that are simple to create and install. They auto-update and are safe to run. And because they bundle their dependencies, they work on all major Linux systems without modification.
Snaps是集装箱化的软件包，他们可以自动更新&安全运行。由于他们打包了需要的依赖，他们可以不经修改，直接在主流Linux系统下工作。
Snaps特点：
- A snap is completely standalone，you could email it to someone and they'd be able to install it and run your ROS system, even if they didn't have ROS installed themselves. Snap程序包是完全独立的，可以在没有安装过ROS的系统上运行。
- If you make your snap available in the Ubuntu Store, whenever you release a new version your users will automatically update.
In order to Sharing the snap with the world you'll need to create a (free) store account at dashboard.snapcraft.io.
