#!/bin/bash

# This is the install script for ghostty-ubuntu (https://github.com/mkasberg/ghostty-ubuntu)
#
# This script is intended to be downloaded and run on the installation target in a single command,
# akin to how Homebrew (https://brew.sh) does it.
#
# /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/mkasberg/ghostty-ubuntu/HEAD/install.sh)"
#
# The goal of this script is to:
#   - Detect the distribution, version, and arch of the installation target
#   - Handle inconsistencies like finding the right Ubuntu version for a corresponding Linux Mint version
#   - Download the correct .deb file
#   - Install it with dpkg
