GitHub Desktop is not officially available for Arch Linux, which is a distribution of Linux that uses the Arch Linux package manager (pacman) to manage software installation. However, you can still use a similar Git GUI client on Arch Linux.
Here are the steps to install a Git GUI client on Arch Linux:
Install the Git package by running the command: sudo pacman -S git
Install a GUI client such as GitKraken, SmartGit, Gitg or Git Cola. You can do this by searching for the package in the Arch Linux package repository using the pacman -Ss package_name command and then installing it using sudo pacman -S package_name command.
Once the installation is complete, you can open the GUI client and sign in to your GitHub account or create a new one. After that, you can start creating or cloning repositories, making changes and committing them, and syncing your local repositories with the remote ones on GitHub.
It’s important to note that the above instructions are subject to change and that the latest version of Git GUI clients may have different installation steps. It’s advisable to check the client’s website for the most up-to-date information and instructions. Also, you may want to check the package availability for your Arch Linux version, some packages may not be available for your version or have different names.
