How to get GIMP 2.99.2 in Linux:

The development release is available as Flatpak package for Linux in the beta channel of flathub repository.

  1. First follow this guide to setup flatpak framework in your Linux.
  2. Then open terminal and run command to add the flathub beta repository:
    flatpak remote-add --user flathub-beta

  3. Finally install GIMP 2.99.2 via command:
    flatpak install --user flathub-beta org.gimp.GIMP

If you also installed the stable GIMP 2.10 via flatpak package, you have to run one more command since Flatpak only allows one visible branch of a same application at once.

flatpak make-current --user org.gimp.GIMP beta

Finally open GIMP from your system application launcher and enjoy! And to switch back the stable version, run command:

flatpak make-current --user org.gimp.GIMP stable
