How to Install RawTherapee:

Option 1: AppImage

The software provides official Linux package via AppImage, which is available for downloading at the link below:

Download RawTherapee (AppImage)

Once you got the package, right-click on it to open file ‘Properties’ dialog and add ‘executable as program’ permission. Finally, click the file to launch the photography processor.

NOTE: Ubuntu 22.04+ does not support AppImage out-of-the-box. In case it doesn’t work for you, press Ctrl+Alt+T on keyboard to open terminal and run command sudo apt install libfuse2 to enable it.

Option 2: Flatpak

RawTherapee is also available as Flatpak package that runs in sandbox and works in most Linux.

1. First, open terminal (Ctrl+Alt+T) and make sure the daemon package is installed by running command in Ubuntu 20.04, Ubuntu 22.04 and higher:

sudo apt install flatpak

Ubuntu 18.04 user can get the package from this PPA.

2. Then, install Rawtherapee as Flatpak by running command:

flatpak install https://dl.flathub.org/repo/appstream/com.rawtherapee.RawTherapee.flatpakref

Like normal package, you can search for and launch the flatpak app from either ‘Activities’ overview or system start menu depends on desktop environment.

(Optional) To remove the Flatpak package, use command:

flatpak uninstall --delete-data com.rawtherapee.RawTherapee

Option 3: Ubuntu PPA

The software does not has an official PPA for Ubuntu user. But you can keep an eye on this page for third-party PPAs.

Or leave comment here to request one. I don’t use RawTherapee, but if you prefer to install it as native .deb I can built it into my personal PPA.
