Snap allows developers to pack their app and dependencies into a single file called snap, which then allows you to run the same app on different linux distros without having to download any dependencies manually.
Now in order to be able to run the same app on multiple different Linux distros, you need to have snap installed on the system where you want to run the app.
In this tutorial, you will learn how to install Snap on Arch Linux.
Step 1 - Download Snap repository
In this tutorial, we are going to install Snap by building snap source. First , you need to download Snap repository on your machine.
To download Snap source, you can simply clone the repository that is available in the AUR repositories.
Run the command below to do this.
git clone https://aur.archlinux.org/snapd.git

Step 2 - Change directory to Snapd
Once you have downloaded Snap source on your machine, proceed to change the directory to Snapd, to do this simply use the cd command
cd snapd

Step 3 - Install Snap
Once you are in the Snapd directory, you can now install Snap. To install Snap, you need to build the source.
To build Snap source, run the command below
makepkg -si
Once the build process is completed, you should be able to use Snap. However, before being able to use Snap, you must restart or logout from your current session on your machine.

Step 4 - Enable Snapd socket
Snap process will not start automatically by default, to make snap process start automatically on boot, you need to enable snapd socket.
To enable snapd socket, run the following command
sudo systemctl enable --now snapd.socket
