Step 1: Refreshing the Ubuntu System Before Grub Customizer Installation
To initiate the installation process, ensuring your Ubuntu system is up-to-date is crucial. Updating the system brings the advantage of having the latest patches, enhanced security, and possibly, better software compatibility. Use the following command to refresh your system:
sudo apt update sudo apt upgrade
Step 2: Integrating the Grub Customizer PPA on Ubuntu 22.04 or 20.04
The next course of action involves incorporating the Personal Package Archive (PPA) for Grub Customizer into your Ubuntu system. The PPA, managed by Daniel Richter, is a repository that contains the Grub Customizer package. This repository enables Ubuntu to know where to fetch Grub Customizer during the installation process.

Step 3: Updating the APT Package Cache after Grub Customizer PPA Import
Now that we’ve added the Grub Customizer PPA, it’s vital to update the APT package cache. The APT package cache is a database that holds references to installable software on the system. An update to the cache ensures that APT is aware of the new packages that have been added, along with their repositories. It allows the system to fetch the latest version of Grub Customizer during installation:
sudo apt update

This is executed by calling upon APT (Advanced Package Tool), the package manager used by Ubuntu, to fetch the software from the PPA we added earlier. By using the install command, we instruct APT to download and set up Grub Customizer on our system:
sudo apt install grub-customizer
Confirm the installation and version of Grub Customizer using the following command:
Grub Customizer, version x.x.x
