Prerequisites for Installation

Before installing Calibre on Rocky Linux 9, ensure that your system meets the following minimum requirements:

• Processor: 1 GHz or faster
• RAM: At least 512 MB (1 GB or more recommended)
• Disk Space: 200 MB free space for installation; more for storing eBooks
• Operating System: Rocky Linux 9 or compatible distributions

Preparing Your Rocky Linux Environment

The first step in installing Calibre is to prepare your system. Start by updating your package manager to ensure all existing software is up to date. Open your terminal and run the following command:

sudo dnf update

This command updates all installed packages on your system. Next, install any essential packages that may be required during the installation process:

sudo dnf install wget

Installation Methods

Method 1: Installing via the Official Script

The easiest way to install Calibre on Rocky Linux 9 is by using the official installation script provided by the developers. This method ensures that you get the latest version of Calibre with minimal effort.

To begin, open your terminal and execute the following command:

sudo -v && wget -nv -O- https://download.calibre-ebook.com/linux-installer.sh | sudo sh /dev/stdin

This command does several things:

• wget: Downloads the installation script from the official Calibre website.
• -O-: Outputs the downloaded script directly to standard output.
• sudo sh /dev/stdin: Executes the script with superuser privileges.

The installation process will begin automatically. Follow any prompts that appear in the terminal. Once completed, you will see a confirmation message indicating that Calibre has been successfully installed.

Post-Installation Steps to Verify Installation

To verify that Calibre was installed correctly, you can launch it from the terminal by typing:

calibre

If everything is set up correctly, this command will open the Calibre application. You can also find it in your applications menu under ‘Office’ or ‘Accessories’, depending on your desktop environment.

Method 2: Installing via Flatpak

If you prefer using a containerized approach, installing Calibre via Flatpak is another excellent option. Flatpak allows you to run applications in isolation from the rest of your system, which can enhance security and compatibility.

Installing Flatpak on Rocky Linux 9

If Flatpak is not already installed on your system, you can do so by running:

sudo dnf install flatpak

Add Flathub Repository

The next step is to add the Flathub repository, which hosts a wide variety of Flatpak applications, including Calibre. Execute this command in your terminal:

sudo flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

Installing Calibre via Flatpak

You can now install Calibre using Flatpak with this command:

flatpak install flathub com.calibre_ebook.calibre

This command downloads and installs Calibre along with all necessary dependencies. Once installed, you can launch it using:

flatpak run com.calibre_ebook.calibre
