As you may know, Darktable is an open-source photo workflow application and RAW developers, managing digital negatives in a database and allowing the users to view them through a zoomable light table. Also, the users can develop and enhance raw images.
In this article I will show you how to install Darktable Unstable, which is the unstable version of the software. While it is not as stable as the regular version, it is the first to receive new features.
Darktable is available via some third party PPA, so installing Darktable on Ubuntu is piece of cake. All you need to do is add the PPA to your system, update the local repository index and install the darktable package:
$ sudo add-apt-repository ppa:pmjdebruijn/darktable-release
$ sudo apt-get update
$ sudo apt-get install darktable
Optional, to remove Darktable, do:
$ sudo apt-get remove darktable
The installation instructions should work on Ubuntu 15.10 Wily Werewolf, Ubuntu 15.04 Vivid Vervet, Ubuntu 14.04 Trusty Tahr and derivative systems like Linux Mint 17.3 Rosa, Linux Mint 17.2 Rafaela, Linux Mint 17.1 Rebecca, Linux Mint 17 Qiana, Pinguy OS 14.04, Elementary OS 0.3 Freya, Deepin 2014, Peppermint 6, Peppermint 5, LXLE 14.04 and Linux Lite 2.
