How to Install and Use Snap Package Manager on Alma Linux 8

The Snap package manager also called snapd is a modern package manager in Linux that allows you to install Snap packages across a wide range of Linux distributions and versions. Snap packages are self-contained and run in a sandbox environment. You can install Snap packages via command-line or download them from the website as a .snap file. Snap is a universal, cross-distribution, and dependency-free package manager. Snap applications packaged with all their dependencies to run on all major Linux distributions.

In this tutorial, I will show you how to install and use the Snap Package Manager on Alma Linux 8.

Prerequisites

  • A server running Alma Linux 8.
  • A root password is configured on the server.

Install Snapd

By default, the Snapd package is not included in the Alma Linux 8 default repo. So you will need to install it from the EPEL repo.

First, install the EPEL repo using the following command:

dnf install epel-release -y

Next, run the following command to install the Snapd package to your system.

dnf install snapd -y

Once the Snapd is installed, start and enable the Snapd service using the following command:

systemctl enable --now snapd.socket
systemctl start --now snapd.socket

You can check the status of the Snapd service with the following command:

systemctl status snapd.socket

You will get the following output:

? snapd.socket - Socket activation for snappy daemon
   Loaded: loaded (/usr/lib/systemd/system/snapd.socket; enabled; vendor preset: disabled)
   Active: active (listening) since Mon 2022-02-28 10:30:21 UTC; 10s ago
   Listen: /run/snapd.socket (Stream)
           /run/snapd-snap.socket (Stream)
    Tasks: 0 (limit: 11412)
   Memory: 4.0K
   CGroup: /system.slice/snapd.socket

Feb 28 10:30:21 linux systemd[1]: Starting Socket activation for snappy daemon.
Feb 28 10:30:21 linux systemd[1]: Listening on Socket activation for snappy daemon.

To check the Snapd version, run the following command:

snap version

You will get the following output:

snap    2.54.3-1.el8
snapd   2.54.3-1.el8
series  16
rocky   8.5
kernel  4.18.0-348.12.2.el8_5.x86_64

Find a Package with Snap

Snap provides an easier way to find your desired package from the Snap repository.

To list all Snap packages available on the Snap repository, run the following command:
