How to Install RawTherapee on Ubuntu 22.04 LTS

The RawTherapee application is a powerful and versatile tool for processing raw photos. This program, which runs on both PC & Mac systems using GTK+ as its interface, uses patches of DCRAW with added support from their in-house team that enhances accuracy where needed most – ensuring every photo comes out beautifully regardless of the type or model device was used when taking them!

In the following tutorial, you will learn how to install RawTherapee on Ubuntu 22.04 LTS Jammy Jellyfish using the Ubuntu default repository or alternative flatpak installation manager for those that require the latest released version as Ubuntu’s releases can be behind due to stability factors in what long term releases are meant for.

Update Ubuntu

Before going into the tutorial, the first step is to run an apt update, which ensures your system is up-to-date to avoid any conflicts.

sudo apt update && sudo apt upgrade -y

Install RawTherapee – APT Method

The first option is to install RawTherapee using the apt command from Ubuntu 22.04 repository. For most users, this is the most recommended way to install it.

In your terminal, use the following command to install.

sudo apt install rawtherapee -y

Install RawTherapee – Flatpak Method

The second option is to use the Flatpak package manager, which is not installed on Ubuntu distributions, given Snap, which is Flatpak’s rival, is owned by Canonical and Ubuntu. However, Flatpak is still available to install from Ubuntu’s default repository.

The extra benefit of using Flatpak installations is that you will always have the most up-to-date version compared to Ubuntu which focuses on stability with older versions that only see updates for security issues or serve bugs.

First, install the Flatpak manager; this can be skipped if you already have it installed.

sudo apt install flatpak -y

Next, you need to enable Flatpack using the following command in your terminal:

sudo flatpak remote-add --if-not-exists flathub

For users installing Flatpak for the first time, 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.



Now install using the following flatpak command.

flatpak install flathub com.rawtherapee.RawTherapee -y

How to Launch RawTherapee

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

In your terminal type:


If you want to launch and use the terminal, send the process to the background to continue using the terminal.

rawtherapee &

Alternatively, Flatpak users will need to launch using the command below from a terminal instance:

flatpak run com.rawtherapee.RawTherapee

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

Activities > Show Applications > RawTherapee


Once open, you can begin using the RawTherapee, and I would advise checking out the Getting started page from the software’s official website. This is unique compared to most other programs of its nature, so it will take a little bit of getting used to.


How to Update RawTherapee

Depending on the method of installation used, the following commands can be used to update the software and any system packages. Ideally, the terminal update command should be used even if you have auto-updates in your desktop GUI to ensure everything is updating correctly.

APT Update Method

sudo apt upgrade && sudo apt upgrade

Flatpak Update Method

flatpak update

How to Remove (Uninstall) RawTherapee

Use one of the following commands to suit the original installation method for users who no longer require the application.

APT Remove Method

sudo apt autoremove rawtherapee --purge -y

Flatpak Remove Method

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

Next, run the following command for any leftover clean-up.

flatpak remove --unused
