How to Install and Use Snap in Various Linux Distributions

Brief: Snaps are Canonical’s way of providing a cross-distribution package management system. In this article, we will see how to install and use snaps in various Linux distributions.

You might be hearing about Snap applications these days. Canonical describes Snap as a universal Linux package which can work on any distribution.

Snaps are basically an application compiled together with its dependencies and libraries – providing a sandboxed environment for the application to run. These are easier and faster to install, can receive latest updates and is confined from the OS and other apps.

An application can be packaged for every Linux desktop, server, cloud or devices in the form of snap. For an application developer, maintaining different package formats and subsequent updates is a pain, which Canonical in the form of Snaps has tried to overcome. It has worked well because more and more applications are now providing Snap packages.

In other words, instead of worrying about DEB packages for Debian/Ubuntu, RPM packages for Fedora etc, you can use Snap package that would work on all Linux distributions with Snap support.

Advantages of snaps

  • Easier to create and manage for Developers: Snaps are easier to create and contain all the dependencies and libraries needed to run, which also means the application uses the latest libraries and do not face any dependencies issues.
  • Automatic Updates: Updates to a snap are delivered automatically on a daily basis, and reaches out to everyone irrespective of the base OS.
  • One snap for everything: be it a desktop, server or cloud.
  • Different releases availability: A snap can be maintained in the stable release, beta versions, and daily build at the same time and you can switch between each other whenever you want.
  • Security: Snaps run in a sandboxed environment, isolated from the rest of your system.

How to install Snap on Linux

How to use Snap on any Linux distribution

Before you Snap packages, you will have to install snapd. snapd is a management environment that handles installation and updates of snaps. Installing snapd will enable Snap support on your Linux distribution.

Let’s see how to install it for different Linux distributions.

Enabling Snap support on Debian and Ubuntu based distributions

If you want to use Snap applications on Linux Mint and other Debian or Ubuntu based distributions, use the command below:

sudo apt install snapd

Enabling Snap support on Fedora based distributions

sudo dnf install snapd

Enabling Snap support on Arch-based distributions

snapd is available in Arch User Repository. Run the below command to install and enable it.

yaourt -S snapd
sudo systemctl enable --now snapd.socket

Enabling Snap support on OpenSUSE based distributions

snapd is not officially included for OpenSUSE. To install in Tumbleweed use the below commands:

sudo zypper addrepo snappy
sudo zypper install snapd

Once the package is successfully installed from the community repo, enable the systemd unit.

sudo systemctl enable --now snapd.socket

How to use snap with the basic Snap commands

Once you are done with the snapd installation, it’s time to see how to use it. We have already covered Snap commands in detail. Here, I’ll just quickly list out the most useful Snap commands.

You can search different snaps and install it. There is a Snap store which holds different public and private apps (or snaps) for clouds, desktops, devices etc.

Finding a snap

Anyone can publish a snap in the store, however, you only see the snaps that are published to the stable release and has been reviewed. Use the below command to search for a snap:

sudo snap find libreoffice

Installing snaps

Once you found the snap you are looking for, you can install it with the below command:

sudo snap install <snap_name>

List out installed snaps

You can use the below command to see the snaps you have installed along with their versions and the developer:

snap list

Update an installed snap app

Snaps are updated periodically to their latest version. In case you are trying to do it manually, type in the below command in the terminal:

sudo snap refresh <snap_name>

Uninstall a snap package

To remove a snap

sudo snap remove <snap_name>

Final Words

With different Linux distributions running different package managers and formats, there is no single way of installing an application in every Linux distribution the same way. Snap can be the solution to this problem, over-coming the installation issues (like a missing library) and making sure you are running the latest version!
