How to install Snap in Fedora24

Snappy Package Manager

Snappy package manager is a transnational package manager. Originally it was built for Ubuntu Operating system, But now it available for all major Linux distros(Fedora, Linux Mint, RHEL, Opensuse etc.). Snap Packages are Universal Linux packages,Unlike Rpm and Debian packages the single snap package can run or install across all Linux Distributions.

The snap format is a single compressed filesystem that is mounted dynamically by the host operating system, together with declarative metadata that is interpreted by the snap system to setup an appropriately shaped secure sandbox or container for that application.

The Advantage with the Snap package is it is a universal package for Linux. The Disadvantage for Snap package is it’s size. To support all linux distributions and dependencies Snap packages are come with all required libraries and dependencies.

We can install Snap packages by using the snapd service, But this service is not pre installed in Fedora.

To install snapd service in Fedora s we have to add  copr repository by using the following command

[[email protected] ~]#dnf copr enable zyga/snapcore
