eidklient_v4.x_installation

#!/usr/bin/env bash

# Install eID klient v4.x on Linux

# Note: There are Two installation methods: (1) running AppImage; or (2) extracting the AppImage into a folder. The latter is a continuation of the former installation method.

# Note: This script is quite messy. It requires some refactoring and tests.

# Note: Tested on Arch Linux.

# TODO: Install D.Launcher (see a note below).


# Installation method 1

# Download
curl -Lo "$tempFile" "$url"

# Extract
mkdir "$tempFolder"

# Note: The AppImage is already executable in DEB according to my tests, however, it never hurts to make sure.
