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
[root@localhost ~]#dnf copr enable zyga/snapcore
Sample Output: You are about to enable a Copr repository. Please note that this repository is not part of the main Fedora distribution, and quality may vary. The Fedora Project does not exercise any power over the contents of this repository beyond the rules outlined in the Copr FAQ at <https://fedorahosted.org/copr/wiki/UserDocs#WhatIcanbuildinCopr>, and packages are not held to any quality or security level. Please do not file bug reports about these packages in Fedora Bugzilla. In case of problems, contact the owner of this repository. Do you want to continue? [y/N]: y Repository successfully enabled.
Once we successfully add and enable the corp repository we will install snapd as follows
