The Snap package manager, known as snapd, is a relatively new feature in the Linux ecosystem. It allows a user to install Snap packages, called Snaps, across a wide range of Linux distributions and versions. This works differently than the traditional method of installing packages via a package manager like APT, where applications are packaged and installed as part of the operating system.
