Install gThumb on Fedora Linux via DNF

Step 1: Update Your Fedora Linux System

To ensure a smooth installation of gThumb, it’s crucial to start by updating your Fedora Linux system. This step helps prevent potential conflicts and maintains system integrity.

Execute the following command in the terminal:

sudo dnf upgrade --refresh

This command refreshes your system’s package database and upgrades all installed packages to their latest versions, ensuring compatibility with new installations.

Step 2: Using DNF to Install gThumb

Fedora’s default DNF repository offers a stable and secure version of gThumb. Although it might not always be as up-to-date as the Flatpak alternative, it’s highly recommended for its reliability and integration with the Fedora system.

To install gThumb using the DNF package manager, run this command:

sudo dnf install gThumb

This command will download and install gThumb from Fedora’s repository. Choosing the DNF method ensures that you get a version that is well-tested and compatible with your Fedora system, although it may not always have the very latest features found in newer versions available through other sources like Flatpak.

Install gThumb on Fedora Linux via Flatpak and Flathub

Step 1: Reinstall Flatpak (If Previously Removed)

In situations where Flatpak has been removed from your system, you’ll need to reinstall it. Flatpak is essential for installing applications in an isolated environment, providing the latest versions of software.

Use the following command to reinstall Flatpak:

sudo dnf install flatpak -y

This command reinstalls Flatpak on your Fedora system, ensuring you can access and manage applications from various repositories.

Step 2: Enabling Flathub for gThumb Installation

Flathub is a major repository for Flatpak applications. Enabling Flathub on your system allows access to a wide range of applications, including the latest version of gThumb.

To add Flathub to your system, execute this command:

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

Step 3: Install gThumb via Flatpak Command

After setting up Flatpak and Flathub, you can proceed to install gThumb. This method ensures you get the most current version of the application. Install gThumb with the following command:

flatpak install flathub org.gnome.gThumb -y

Executing this command installs the latest version of gThumb from Flathub, providing you with up-to-date features and improvements.

Troubleshooting gThumb Flatpak Installation on Fedora

Occasionally, you might encounter issues during the installation process. One common error is an inability to fetch summaries from the Flathub remote. If you encounter this, use the following command to resolve it:

flatpak remote-modify --enable flathub

This command re-enables the Flathub repository, fixing the issue and allowing the installation of gThumb to proceed smoothly.

For those who installed gThumb via Flatpak, a different command is required. Launch gThumb with this command:
