Adopting Nomacs on your Fedora system means not just accessing your images but optimizing how you interact with them, whether for a quick review or detailed editing.

Let’s explore the steps required to install Nomacs on Fedora Linux and set the stage for a more efficient image viewing and management experience.

Install Nomacs on Fedora via DNF

Step 1: Refresh Fedora Packages Before Nomacs Installation

Before initiating the installation of Nomacs, it is crucial to update your Fedora system. An up-to-date system ensures compatibility and security for the new software. To update your system, access the terminal and execute the command:

sudo dnf upgrade --refresh

This command refreshes the repository metadata and upgrades all the packages to their latest versions, resolving potential conflicts.

Step 2: Install Nomacs via DNF Command

Fedora’s DNF package manager is the preferred method for installing software due to its efficient handling of dependencies and integration with Fedora’s repositories. Given Fedora’s biannual release cycle and frequent updates, DNF typically offers the most recent version of the software.

To install Nomacs using DNF, input the following command:

sudo dnf install nomacs

This command will download and install the Nomacs Image Viewer and any required dependencies.

For those who prefer installing Flatpak packages, the following section offers an alternative method.

Install Nomacs on Fedora via Flatpak and Flathub

Step 1: Re-install Flatpak on Fedora for Nomacs (Situational)

If Flatpak has been removed from your Fedora system, it can be easily re-installed. Re-installing Flatpak ensures that you can manage applications outside of Fedora’s standard repositories.

Use this command to re-install Flatpak:

sudo dnf install flatpak -y

This command re-installs the Flatpak package manager and includes the -y flag to automatically confirm the installation, streamlining the process.

Step 2: Enable Flathub for Nomacs Installation

To access a broader range of applications, including Nomacs, enable the Flathub repository. Flathub is the go-to source for Flatpak applications, providing a diverse selection of the latest software. Enable Flathub using this command:

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

This command adds the Flathub repository to your Flatpak configuration if it isn’t already present.

Step 3: Install Nomacs via Flatpak Command

With Flathub enabled you can proceed to install Nomacs. Execute the following command to start the installation:

flatpak install flathub org.nomacs.ImageLounge

This will fetch and install the Nomacs image viewer from the Flathub repository.

Troubleshoot Nomacs Flatpak Installation

A common issue encountered during Flatpak installations is a disabled Flathub repository, which results in an error. If you come across an error indicating an inability to fetch data from Flathub:

"error: Unable to load summary from remote flathub: Can't fetch summary from disabled remote 'flathub,"

The fix is simple: run the following command to enable Flathub.

flatpak remote-modify --enable flathub

This will re-enable the Flathub repository, resolving the error and allowing the installation of Nomacs to proceed.

Launch Nomacs on Fedora Linux

After successful installation, you can open Nomacs using either the command-line interface (CLI) or the graphical user interface (GUI) on your Fedora system.

CLI Commands to Launch Nomacs

For immediate access, open Nomacs from the terminal with this simple command:

nomacs

This command activates Nomacs directly from the terminal, providing a quick way to open your image viewer.

For Flatpak installations, the launch command differs slightly. Enter the following in your terminal to open Nomacs:

flatpak run org.nomacs.ImageLounge

This specifies that Flatpak should run the Nomacs application identified by its unique Flatpak identifier.

GUI Method to Launch Nomacs

Most users prefer the graphical method for its convenience. To launch Nomacs without the command line, navigate through the following path on your desktop environment:

1. Click on the “Activities” hotspot or button.
2. Select “Show Applications” or use the equivalent application menu.
3. Search for “nomacs” and click its icon to open the application.

This GUI pathway avoids command memorization and provides a user-friendly alternative to the CLI method.
