How to Install Darktable 2.4.0 in Ubuntu:

You can install Darktable in Ubuntu 16.04, Ubuntu 17.04, Ubuntu 17.10 and higher either via traditional Ubuntu PPA or using the Snap (run in sandbox) package.

Install Darktable via PPA:

CHECK the PPA link before doing following steps, since the new packages may not ready when you try to install them.

1. To add the PPA, open terminal emulator (Ctrl+Alt+T) and run command:

sudo add-apt-repository ppa:pmjdebruijn/darktable-release

Type in the password when it prompts and hit Enter.


2. To upgrade from a previous release, launch Software Updater (Update Manager) and install the available updates:


Or run commands in terminal to install or upgrade the software:

sudo apt-get update

sudo apt install darktable

3. (Optional) To remove the PPA, launch “Software & Updates” utility and navigate to “Other Software” tab.

And remove darktable via following command if you want:

sudo apt-get remove --autoremove darktable

Install Darktable via Snap package:

A snap is an universal Linux application with all its dependencies bundled. It runs in sandbox and is isolated from other system software.

Darktable is available as Snap. You can simply open Ubuntu Software, search for and install Darktable:


Besides the traditional package (the last one), you can see two new darktable packages. They are snaps maintained by different maintainers.

Check the package version and select install one. (I chose “darktable-empanada”). Or simply run command in terminal (Ctrl+Alt+T):

snap install darktable-empanada --classic


The snap co-exists with traditional Darktable package. So you may have two shortcut icons in the application launcher.
