I have Kstars/Ekos installed on my Linux Mint desktop. Whats the best way to uninstall previous version and install latest stable release. I read on the internet that one should use aptitude and the purge option.

irst, 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
Would this work?

Why do you want to purge the old version? Why not directly update to the latest version?

I am sorry I am ignorant. So you would have 2 versions installed simultaneously? Wouldtheir be any conflicts with libraries and modules?

No you won’t have two versions, when you run the updater on your system it will just update the version you have to the latest one, so you will just have one and it will be the latest... ....simples...

So you will get the nightly built from the launchpad, which is the most updated version of Kstars/ INDI from Jasem.
