How to Install Gwenview on Fedora 36 Linux

Gwenview is a simple and easy-to-use program for viewing images on the KDE desktop. It can show you full-screen slideshows, crop an image or rotate it in many different ways without much effort from yourself!

Features:

  • Supports simple image manipulations: rotate, mirror, flip, and resize
  • Supports basic file management actions such as copy, move, delete, and others
  • Functions both as a standalone application and an embedded viewer in the Konqueror web browser
  • It can be extended using KIPI plugins.

In the following tutorial, you will learn to install the Gwenview on Fedora 36 Linux using one of two methods: DNF package manager or Flatpak package manager, with some tips for maintaining or removing Gwenview in the future.

Update Fedora Linux

The first step is to make sure your system is up-to-date to avoid issues during the installation and for good practice. This is done by opening your terminal and using the following command.

sudo dnf upgrade --refresh

Install Gwenview – 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 This is a stable and secure version and is most recommended to install over any other package manager but can be outdated compared to Flatpaks alternative option that is usually up-to-date.

First, execute the following DNF install command.

sudo dnf install gwenview -y

Flatpak users that would like to install Gwenview using the alternative package manager, follow the instructions below.

Install Gwenview – 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.kde.gwenview -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 Gwenview

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

In your terminal type:

gwenview

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

gwenview &

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

flatpak run org.kde.gwenview

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

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

Example:

How to Update/Upgrade Gwenview

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) Gwenview

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 gwenview -y

Note, autoremove will also delete any unused packages from Gwenview 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.kde.gwenview -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
