Resolved after I upgraded to this morning's release:

Unpacking kstars-bleeding (6:3.6.0+202208280917~ubuntu22.04.1) over (6:3.6.0+202208270719~ubuntu22.04.1) ...

Hello,
Yes, I noticed. But your procedure did not fix the issue on my side.

Hello,
I made the decision to perform a full install of my system with Ubuntu 22.

Now, it is even worse, kstars cannot even start:

Hello,
I tried with version 3.6.0: same result.

Here is the output of ekos debugger:

Hello,

I upgraded to the latest stable versions of indi/kstars.
Now, the app is crashing every time the Image viewer displays the incoming image.

I reproduce using the simulators.

My env:
Ubuntu 18.04.6
kstars 3.5.9 stable Build: 2022-06-13T06:24:40Z

Attached logs.
journalctl show:
Aug 21 16:38:03 florian-U36SD kernel: ExtractorSolver[22103]: segfault at 7f23ac3e16c8 ip 00007f23abd45a8c sp 00007f23694c9ad0 error 7 in libQt5Core.so.5.9.5[7f23abca200c8 ip 00007f23abd45a8c sp 00007f23694c9ad0 error 7 in libQt5Core.so.5.9.5[7f23abca2000+53b000]

Thank you for any help

Hello Jean-Luc,

I have the same devices (WATEC + stk1160) and I can successfully open the stream in ekos using directly V4L2 CCD.

However, I cannot take single captures (my goal is to perform astrometry), even when selecting stack: Additive option.

It says: "Absolute exposure duration control is undefined and tacking is not supported".
Logs attached.

Did you manage to make it work on your side?
Thank you and clear skies

Hello,
I tried again tonight, and it seems in my case, it was just due to bad polar alignment.
Clear skies,
Florian

Hello,
Tonight I am getting the same weird behavior as you described.
The east calibration is using the wrong direction, using both st4 or direct pulses, using phd guiding or ekos internal guider.
Sending manual orders works fine.
I changed the gemini2 battery today because it was depleted.
Still have no clue on your side?

Hello,

I connected Ekos to the AZ GTi mount successfully, but the goto actions seem irrelevant.
For example, when moving only in altitude, it also moves in azimuth (is it using equatorial mode?).
When connecting with the Android app, it does say Alt mode.

Thank you and clear skies!

Hello,

On my side, I am using the notifications to launch a small java program playing a mp3 file.
This warns me when the sequence stopped, and I can snooze it by closing the app (which you cannot do if you run the sound directly).

However, I did not find the appropriate event to use.
For example, when I stop the sequence manually, the alarm is triggered.

Hello, this is unfortunately not true. Only the focuser temperature will work. Not the observatory one. The weather temperature was added after my feature implementation, and was not made available to it.

I would also advise, like others, to start telescope cooling more in advance, so that it gets more stable sooner.

Clear skies.

Hello,
If your focus issue is indeed due to the temperature, I think it could be solved by the feature I recently developed : trigger autofocus on temperature change. It uses the focuser probe, if available, to compare the last focus temperature to the current temperature, and triggers the autofocus in case it reaches the specified limit.

The feature should be delivered in the next release, but you can test it with the nightly.

Clear skies!

Hello,

How could it be possible to have drift if you are guiding?
