Cubic is a GUI wizard is a tool that allows you to create custom Live ISO images for Ubuntu and Debian-based Linux distributions. In this article, we’ll go through the steps of using Cubic to create your own custom Ubuntu ISO.

Step 1: Install Cubic

You can do this by adding the Cubic PPA to your system and installing it through the terminal. Here are the commands:

sudo add-apt-repository ppa:cubic-wizard/release
sudo apt update
sudo apt install cubic

Step 2: Launch Cubic

Once Cubic is installed, you can launch it from the Applications grid. It will prompt you for your password to gain root access.

Step 3: Create a New Project

The Cubic interface is split into several logical pages. The first thing you need to do is create a new project. Click on the “New Custom Ubuntu ISO” button to get started.

Step 4: Choose the Ubuntu Base

The next page allows you to choose the Ubuntu base for your custom ISO. You can choose between Ubuntu Desktop, Server, or Minimal. You can also choose the Ubuntu version you want to use.

Step 5: Customize Packages

The next page allows you to customize the packages that will be included in your custom ISO. You can choose to add or remove packages, and you can also specify which version of each package you want to use.

Step 6: Configure the Filesystem

The next page allows you to configure the filesystem of your custom ISO. You can specify the size of the ISO, the compression method to use, and the file system type.

Step 7: Customize the ISO

The next page is the Terminal page, which gives you root access to a virtual environment where you can fine-tune things by hand. This is where you can make any customizations you want that aren’t available through the GUI.

Step 8: Preview and Build the ISO

Once you’ve made all your customizations, you can preview your ISO by clicking the “Preview” button. This will show you what the ISO will look like before you build it. If you’re happy with the preview, you can build the ISO by clicking the “Build” button.

Step 9: Save the ISO

After the ISO is built, you can save it to your system. You can choose to save it as an ISO file or as a USB image that you can write to a USB drive.
