Install PhotoQT on Ubuntu 22.04 or 20.04 via APT

To leverage the full power of PhotoQt on your Ubuntu system, we will guide you through a detailed installation process using the APT (Advanced Package Tool). This tool is Ubuntu’s default package manager, which handles packages for the operating system. To ensure a smooth installation process, we will update your system and select a suitable installation method.

Step 1: Update Your Ubuntu System Before the PhotoQT Installation

Before proceeding with the installation, updating your existing system packages is crucial. This step is necessary to avoid conflicts with outdated packages that could interfere with the new installation. This also ensures that your system has the latest security patches and updates applied. By executing the following commands, you will update and upgrade your Ubuntu system:

sudo apt update
sudo apt upgrade

The sudo apt update command fetches the package information from all configured sources while sudo apt upgrade upgrades all the currently installed packages to their latest versions.

Step 2: Install PhotoQT on Ubuntu 22.04 or 20.04 via APT Command

Once your system is updated, you have two options to install PhotoQt using the APT package manager:

Option 1: Install PhotoQt using the Ubuntu APT Repository

Utilizing Ubuntu’s default repository for installing PhotoQt is highly recommended for stability. While this method may not include the latest features (depending on your Ubuntu version), it ensures the most minor compatibility issues with your system. The Ubuntu repository houses software versions thoroughly tested to work with Ubuntu.

To install PhotoQt using Ubuntu’s repository, run the following command:

sudo apt install photoqt

Option 2: Install PhotoQt using the PPA Method on Ubuntu

An alternative method for using the APT package manager is to import and install the Personal Package Archive (PPA) maintained by Lukas Spies. This method often provides a more updated version of PhotoQt with recent features.

Firstly, import the repository with the following command:

sudo add-apt-repository ppa:lumas/photoqt -y

This command adds the PPA to your system’s software sources, which enables APT to fetch and install packages from this PPA.

Before proceeding, run an APT update to reflect the newly imported PPA in your system’s package list:

sudo apt update

Now, you can install the application by executing the following command:

sudo apt install photoqt

This command will fetch and install the latest version of PhotoQt from the added PPA.

If you installed the Ubuntu APT version already want want to upgrade, re-run the installation command to ensure all packages are installed correctly.

Install PhotoQt on Ubuntu 22.04 or 20.04 via Flatpak and Flathub

If you’re looking for an alternative installation method, you might want to consider using Flatpak—an increasingly popular universal package management system similar to Snap. Flatpak operates in a sandbox environment, isolating software dependencies and providing increased security. Flatpak also allows you to access and install applications that might not be available in your distro’s standard repositories. PhotoQt, being one of those applications, can be installed via Flatpak from the Flathub repository.

Step 1: Enable Flathub Repository for PhotoQT on Ubuntu

Before installing PhotoQt, enabling the Flathub repository, the primary hub for Flatpak applications is crucial. Flathub houses a plethora of applications packaged in the Flatpak format and, thus, enables users to install these applications conveniently.

To add the Flathub repository to your Flatpak configuration, execute the following command in your terminal:

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

This command instructs Flatpak to add the Flathub repository, ensuring you can access many applications, including PhotoQt.

Step 2: Install PhotoQt on Ubuntu 22.04 or 20.04 via Flatpak Command

With Flathub now available as a source, you can install PhotoQt using the flatpak install command. This command will fetch the PhotoQt package from Flathub and install it on your system.

Execute the following command in your terminal:

flatpak install flathub org.photoqt.PhotoQt -y

This command installs PhotoQt from the Flathub repository, ensuring you have the latest version of the application.

If your system does not have Flatpak installed, please refer to our guide on “How to Install Flatpak on Ubuntu” for step-by-step instructions on installing the most recent supported version of Flatpak. This will equip your system with the necessary tools to manage and use Flatpak applications.

Launching PhotoQt on Ubuntu 22.04 or 20.04

After successfully installing PhotoQt, the next step is launching the application and exploring its robust features. There are multiple ways to open PhotoQt, using the command line or the graphical user interface (GUI).

Launch PhotoQt from the Terminal on Ubuntu

For users comfortable with the command line, launching PhotoQt is as simple as typing a command into the terminal. Run the following command to start PhotoQt:

This command signals your system to initiate the PhotoQt application.

If you installed PhotoQt via Flatpak, you must use a slightly different command to open the application. Execute the following command in your terminal:

flatpak run org.photoqt.PhotoQt

This command instructs Flatpak to run the PhotoQt application from the installed packages.

Launch PhotoQt from the GUI on Ubuntu

For most desktop users who prefer using the graphical interface, launching PhotoQt is a straightforward process. You can access the application using the built-in application menu of your Ubuntu system.

Follow this path to open PhotoQt:
