How to Install gThumb on Ubuntu 22.04 LTS

gThumb is the perfect tool for viewing and editing all your favorite images. It’s fully integrated with GNOME 3, so you can access it in seconds. The imaging software provides an easy way to view common formats such as BMPs GIF(including animations), JPEGs PNG TIFF, or RAW files — not just typical multimedia types like videos that are usually found on other platforms. You’ll also be able to use various metadata tags embedded inside photos including EXIF IPTC XMP which allows more customization than ever before when organizing collections across multiple devices

In the following tutorial, you will learn to install the gThumb on Ubuntu 22.04 LTS Jammy Jellyfish using three methods: apt package manager and flatpak package manager with some tips for maintaining or removing gThumb in the future.

Update Ubuntu

Before you begin, make sure your system is up-to-date to avoid any conflicts during the installation, and for good practice, use the terminal command as follows.

sudo apt update && sudo apt upgrade -y

Install gThumb – APT Method

The first option is to use the Ubuntu 22.04 default APT repository. This is a stable and secure version and is most recommended to install over any other package manager but can be outdated compared to Flatpaks alternative option that is usually up-to-date.

First, execute the following apt install command.

sudo apt install gThumb -y

The following Flatpak method will install the latest gThumb for those that want to stay with the absolute latest version, especially as Ubuntu 22.04 LTS ages.

Install gThumb – Flatpak Method

The second option is to use the Flatpak package manager. This comes installed on Ubuntu unless you removed it. This is another popular option similar to Snap but is featured amongst many distributions as an alternative third-party installation package manager for the latest packages.

First, re-install Flatpak if you have removed the package manager previously.

sudo apt install flatpak -y

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

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

Ideally, you should reboot at this stage; if you skip this and notice icons not appearing, the reboot will generate the paths required for the future.


Now run the installation using the following flatpak command.

flatpak install flathub org.gnome.gThumb -y

How to Launch gThumb

Now that you have the software installed, launching can be done in a few ways.

In your terminal, type the following command.


If you would like to launch gThumb and continue using the terminal, use the <application-name> & command.

gthumb &

Lastly, Flatpak users can run from the terminal using the following command.

flatpak run org.gnome.gThumb

However, this isn’t practical, and you would use the following path on your desktop to open with the path.

Activities (top-right corner) > Show Applications > gThumb


Once you open gThumb, you will see the first default landing screen.

Once you have finished the above, you can begin using the imaging software.
