Automating Post-Installation Setup on Pop!_OS with Custom Scripts

Table of Contents

Setting up a new operating system can be a tedious task, especially when it comes to installing essential software, configuring the environment, and setting up aliases for frequently used commands. To simplify this process, I created a set of scripts that automate the post-installation setup of Pop!_OS (22.04 LTS). In this post, we will take a look at the project and show how to use it to quickly set up your system.

Post-installation script for the Pop!_OS (22.04) distribution, based on Ubuntu. The script contains internet verification and whether wget is installed on the device. Also, install apt, flatpak and deb packages; updates repositories, performs system cleanup and add custom alias

Project Overview
#

The project consists of several scripts that perform various tasks, such as installing software packages, configuring custom aliases, and setting up the development environment. The main scripts are:

LICENSE
misc/
  swapAudio.sh
  syncthingStatus.sh
  update.sh
README.md
run.sh
src/
  alias.sh
  devEnv.sh
  githubClone.sh
  homeScript.sh
  post-install.sh

Getting Started
#

Step 1: Clone the Repository
#

First, clone the repository to your preferred location. In this example, we will clone it to the Downloads folder:

git clone https://github.com/geraldohomero/post-install-pop-os.git $HOME/Downloads/post-install-pop-os

Step 2: Make the Scripts Executable
#

Navigate to the cloned repository and make the scripts executable:

cd $HOME/Downloads/post-install-pop-os
chmod +x *.sh src/*.sh misc/*.sh

Step 3: Run the Post-Installation Setup Script
#

Run the run.sh script to start the post-installation process:

The script will display colorful and informative messages as it progresses through the installation and configuration steps. You may need to provide your password for certain operations that require administrative privileges.

Step 4: Follow the On-Screen Instructions
#

The setup script will guide you through the installation process. It will:

  • Run the src/post-install.sh script to install software packages and perform system cleanup.
  • Run the src/alias.sh script to configure custom aliases.
  • Copy utility scripts (update.sh, misc/syncthingStatus.sh, and misc/swapAudio.sh) to the home directory and make them executable.
  • Run the src/devEnv.sh script to install development tools.
  • Run the src/githubClone.sh script to clone all repositories of a specified GitHub user.

Step 5: Customize Aliases and Installed Programs
#

You can modify or add your own custom aliases in the src/alias.sh script to suit your workflow. Edit the CUSTOM_ALIASES array with the desired aliases and run the src/alias.sh script again to update your .bash_aliases file.

Step 6: Review Installed Software and Aliases
#

After the setup is complete, you can review the installed software and aliases on your system. The src/post-install.sh script installs software packages listed in its configuration, while the src/alias.sh script configures custom aliases.

Step 7: Use Utility Scripts
#

The utility scripts misc/update.sh, misc/syncthingStatus.sh, and misc/swapAudio.sh are copied to your home directory and made executable. You can use them as follows:

  • update: Updates and upgrades the system.
  • syncstatus: Checks the status of Syncthing.
  • swap: Switches audio output channels.

Conclusion
#

By following these steps, you can automate the post-installation setup for Pop!_OS, saving time and ensuring a consistent environment across installations. Feel free to customize the scripts to meet your specific needs and workflow.
