OK, here it is:
Ubuntu is distributing KStars version 2.4.0 (KDE 5.18.0)
INDI library: 1.1.0
Code Rev: 2039 Protocol 1.7
Also, I do not wish to contradict myself, but now "Telescope Simulator" works and "V4L2 CCD" works.
Please note that I had difficulty installing it.
It turns out that you need to make a change to the "Software & Updates" program accessible from "System Settings" (I am running Ubuntu 16.04 LTS)
Click the "Other Software" tab
You must uncheck anything that looks like "
ppa.launchpad.net/mutlaqja/ppa/ubuntu xenial" (This is preventing KStars from launching)
Then try installing KStars.
In summary, I don't know what the deal was yesterday when INDI drivers were crashing. It is a big unknown to me. Somehow I think that the "ppa.launch" thing was messing things up (how do you like that for tech-speak!)
Anyhow from what I see, the "ppa.launchpad" thing doesn't negatively impact when I am running "bleeding". (Perhaps someone could explain to this Linux-newbie what the "H" this is
To me it still seems like a reasonable thing to ask what version of KStars is compatible with versions of INDI. Is it backwards compatible?
