GIMP is a free and open-source raster graphics editor used for image retouching and editing, free-form drawing, converting between different image format, and more specialized tasks.
Using the official package from your Unix-like distribution is the recommended method of installing GIMP. Although, you might want to use the flatpak build as it is likely to provide fastest updates. Follow the following instructions for installing GIMP with flatpak.
Open a terminal and type the following:
flatpak install https://flathub.org/repo/appstream/org.gimp.GIMP.flatpakref
Then, once installed, you may launch the program. Depending of your system, it might be available in your launch menu. If not, simply type the following command in a terminal to launch the newly installed GIMP:
flatpak run org.gimp.GIMP//stable
Once a new update is available, your distribution should inform you that a new version is available. You can always do a manual check by using this simple command:
