If you are interested to try a Linux OS on your own Windows PC, we recommend to install the current distribution of Ubuntu. You can install Ubuntu onto a computer alongside a copy of Windows. You will be able to select whether to start Ubuntu or Windows each time your computer starts up or you can try to run Ubuntu on a CD or even on a memory stick alongside your current system.

Installation of QGIS and OTB on Ubuntu 18 ("Bionic Beaver")

Use the repository "ubuntugis-unstable". Please remove all previously installed QGIS und GRASS packages that were installed from other repositories: otherwise conflicts between different package versions might occur!

Open a terminal (Ctrl + Alt + t), copy and paste:

sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-key CAEB3DC3BDF7FB45
sudo apt-get update
sudo apt-get install qgis qgis-plugin-grass python3-matplotlib python3-scipy 
sudo apt-get install otb-bin otb-bin-qt python-otb

Installation and Konfiguration of the OTB-QGIS-plugin is the same as Windows OTB Plugin installation. First install the OTB plugin, second adopt path names for OTB folder and OTB Application folder: Settings --> Options --> Processing --> Providers --> OTB
