How to Install PhotoQT on Ubuntu 22.04 LTS

PhotoQt is a simple, open-source image viewer designed to be more than the average image viewer with much more eye candy, highly configurable, and easy to use. PhotoQt is written in Qt, making it a platform-independent software that supports Linux, Mac OS X, and Windows operating systems.

PhotoQt has several features that make it unique among image viewers. First, PhotoQt is highly configurable, allowing users to customize how the program looks and behaves. Second, PhotoQt is very easy to use, with an intuitive interface that makes navigating through images quick and easy. Finally, PhotoQt is extremely fast, making it ideal for viewing extensive image collections and an excellent choice for a simple yet powerful image viewer.

The following tutorial will teach you how to install PhotoQT Ubuntu 22.04 LTS Jammy Jellyfish using a LaunchPAD APT PPA with the command line terminal.

Update Ubuntu

First, update your system to ensure all existing packages are up to date to avoid conflicts.

sudo apt update && sudo apt upgrade -y

Install PhotoQT – APT PPA Method

The best method to use the APT package manager is to import and install the PPA by Lukas Spies.



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

Before you continue, run an APT update to reflect the newly imported PPA.

sudo apt update

Now install the application.

sudo apt-get install photoqt -y

Install PhotoQT – Flatpak Method

The second option is to use the Flatpak package manager. Flatpak is not installed natively on Ubuntu 22.04, given Canonical is behind both Ubuntu and Snaps, but it is available to install if you so wish.

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, such as paths not being generated for icons.

sudo reboot

SKIP THE REBOOT IF FLATPAK IS INSTALLED.



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

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

Now install PhotoQT using the following flatpak command.

flatpak install flathub org.photoqt.PhotoQt -y

How to Launch PhotoQT

Launching can be done in a few ways now that you have the software installed.

First, the software can be launched using the following command.

photoqt

Alternatively, Flatpak users will need to launch using the command below from a terminal instance.

flatpak run org.photoqt.PhotoQt

Most desktop users may elect to use the application icon to open the software which can be achieved using the following path.

How to Update/Upgrade PhotoQT

The best method to ensure your installation of PhotoQT is up-to-date is to open the command line terminal and run the following command.

Depending on the method of installation used, the following commands can be used to update.

APT Update Method

sudo apt upgrade && sudo apt upgrade

Flatpak Update Method

flatpak update

The command will also ensure all other packages that use the APT package manager, including your system packages, are up-to-date. I suggest that users new to Linux run this command frequently to ensure your system works as intended, even if you have automatic GUI updates or notifications.

How to Remove (Uninstall) PhotoQT

Use one of the following commands to suit the original installation method for users who no longer require the application.

APT Remove Method

sudo apt autoremove photoqt -y

Next, you should remove the PPA for users who will not use the software again.

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