Thank you for this suggestion!

I can't see how to get to the driver settings without connecting the camera first. The INDI control panel is greyed out in Ekos and the settings are not available without a device connected. But if I connect the camera, kstars crashes without a trace.

How did you get past this problem? How did you access the driver parameters ?

Thanks again,


Happy to provide something if I can figure out how.

KStars just disappears from the screen. No message, no window full of text. Nothing.

Is there a core dump someplace that would help diagnose this?

100% repeatable crash.


Simulators work fine. I've tried both 3.6.5 stable and 3.6.6.

Downloaded Mac binaries from binary-factory.kde.org/view/MacOS/job/KStars_Release_macos/

Any suggestions?

Because of previous failed install attempts, I had to start with

sudo apt update --fix-missing
sudo dpkg --configure -a

Then the exact steps you did worked for me.

I have just installed ubuntu 22.04 on a pi4, and confirm that stars 3.5.9 stable installs perfectly from the ppa.

Good news! The performance of stars and ekos under Gnome in jammy seems noticeably more snappy than in 20.04. I haven't tried an actual imaging session yet, but this is really an improvement.

Thank you for your help!

It's repeatable in that Ekos eventually crashes pretty much every imaging session. Not repeatable in that it runs just fine for hours and then crashes at apparently random times when I'm asleep.

I will continue to try to document the crashes. Perhaps this is the wrong place to post the crash reports?

Should I just provide a link to the last successful saved image as the one that "caused it?"

Here's a crash last night in KStars 3.5.9 beta ubuntu 20.04.3 nightly spa

In case anybody else wants to do this, the procedure is to install as Jasem said

sudo apt install -y ekos-debugger

But then run by typing


(without the dash). This starts a GUI from which you can launch KStars and INDI, but which will trap crashes and collect crash data.


Thank you!

And then to run inside the debugger, do I just run ekos-debugger from the shell?


I've been having a lot of crashes lately and would like to run kstars/ekos in the debugger so that I can submit crash reports.

I used to do this but it's been years, and I don't remember how to run it this way. I see the git for the debugger but I need a step-by-step on how to actually run this way.

Running KStars 3.5.8 stable on ubuntu 20.04.3 LTS on amd64 hardware.

Many thanks!
