Hello Linux Geeksters. As you may know, Rawtherapee is an open-source image processing software (similar to Adobe Lightroom), written in C++ and using GTK+ as frontend. The latest version available is Rawtherapee 4.1, which has been recently released, coming with both new features and support for many cameras. For a list of new features and improvements, visit the official site.
In this article I will show you how to install Rawtherapee 4.1 on Ubuntu 14.04 Trusty Tahr, Linux Mint 17 Qiana, Pinguy OS 14.04, Elementary OS 0.3 Isis and other Ubuntu 14.04 derivatives.
Because it is available via some third party PPA, installing Rawtherapee 4.1 on the listed Ubuntu, Linux Mint, Pinguy OS and Elementary OS systems is easy. All you have to do is add the ppa to your system, update the local repository index and install the rawtherapee package. Like this:
$ sudo add-apt-repository ppa:dhor/myway
$ sudo apt-get update
$ sudo apt-get install rawtherapee
Optional, to remove rawtherapee, do:
$ sudo apt-get remove rawtherapee
