When I select a Linux version to run, I always use the latest stable long term release version. For example, for XFCE based Xubuntu, I am now on 16.04.
However, being with a long term release version means that for some software packages, you will have older versions. One such case is telescope automation platform, Ekos and the associated INDI Library.
To make sure that you are running the latest Ekos and INDI library, you can do the following:
First, purge all the KStars and INDI packages, if they are installed:
sudo aptitude purge indi-bin libindi-data libindi1 libindidriver1
sudo aptitude purge kstars kstars-data
Add Jasim Mutlaq's PPA respository for KStars, and INDI. It includes Ekos as part of KStars.
sudo apt-add-repository ppa:mutlaqja/ppa
sudo aptitude update
Now, install latest KStars, with full INDI
sudo aptitude install indi-full kstars-bleeding
Now, you can use any feature that is available in this platform, from telescope control, image capture, guiding, Polar Alignment, and much more.
