Update Ubuntu

The first step is to make sure your system is up-to-date to avoid issues during the installation and for good practice. This is done by opening your terminal and using the following command.

sudo apt update && sudo apt upgrade -y

Install Calibre – APT Method

The first method is to install Calibre from Ubuntu 22.04 default repository, giving you a stable, reliable version of the software but can lag in the future as LTS means stability over new features.

Use the following command to install Calibre as follows.

sudo apt install calibre -y

Install Calibre – Flatpak Method

The second option is to use the Flatpak package manager, which is not installed on Ubuntu distributions, given Snap, which is Flatpak’s rival, is owned by Canonical and Ubuntu. However, Flatpak is still available to install from Ubuntu’s default repository.

First, install the Flatpak manager if it was removed previously.

sudo apt install flatpak -y

For users installing Flatpak for the first time, it is often recommended to reboot your system. Failure to do this can occur with odd issues arising, such as paths not being generated for icons.



Next, you need to enable Flatpack using the following command in your terminal:

sudo flatpak remote-add --if-not-exists flathub

flatpak install flathub com.calibre_ebook.calibre -y
