How to Install gThumb on Fedora 36 Linux

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 standard 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 when organizing collections across multiple devices.

In the following tutorial, you will learn to install the gThumb on Fedora 36 Linux using two methods: dnf package manager and flatpak package manager, with some tips for maintaining or removing gThumb in the future.

Update Fedora Linux

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 dnf upgrade --refresh

Install gThumb – DNF Method

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 This is a stable and secure version and is most recommended to install over any other package manager but can be outdated compared to Flatpaks alternative option that is usually up-to-date and sometimes ahead of the Fedora repository.

First, execute the following DNF install command.

sudo dnf install gThumb -y

The following Flatpak method will install the latest gThumb for those that want to stay with the absolute latest version.

Install gThumb – Flatpak Method

The second option is to use the Flatpak package manager installed on Fedora-based systems. The extra benefit of using Flatpak installations is that you will always have the most up-to-date version. However, with distributions such as Fedora or similar types that focus on the latest packages, the significant advantage is often not as substantial or not present. However, still, this is the user’s discretion in choosing.

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

sudo dnf install flatpak -y

For users re-installing Flatpak, 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.

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

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.

reboot

Now run the installation using the following flatpak command.

flatpak install flathub org.gnome.gThumb -y

If the above command does not work and you receive the “error: Unable to load summary from remote flathub: Can’t fetch summary from disabled remote ‘flathub’ use the following command.

flatpak remote-modify --enable flathub

This will fix the issue.

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.

gthumb

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

Example:

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.

How to Update/Upgrade gThumb

Updates should appear in notifications, but if these fail to show sometimes, it is recommended to check using the terminal regardless use one of the following commands to check for updates.

DNF Method

sudo dnf update --refresh

Flatpak Method

flatpak update

How to Remove (Uninstall) gThumb

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

DNF Remove Method

sudo dnf autoremove gthumb -y

Note, autoremove will also delete any unused packages from gThumb and any other leftovers from previous applications. Most times, this is safe to do and should be done to keep your system from being bloated.

Flatpak Remove Method

flatpak remove  --delete-data org.gnome.gThumb -y

Next, run the following command for any leftover clean-ups required, similar to the autoremove command described for the DNF remove example command.

flatpak remove --unused

In the tutorial, you have learned how to install gThumb on Fedora 36 Linux using one of the three installation methods.
