Thank you.

Two weeks ago I opened the chamber of three ST-7's I have and cleaned the CCD's. When I was about to check that work, the filter turret went haywire.
At that time, there was a system update before I started the checking process and when I tried to operate the camera from KStars, it crashed. I then noticed that there was an update for KStars, and when I updated it, KStars was up and running, but only the filter turret function was malfunctioning.
I did restart the camera driver as the first thing I did. I just happened to notice the button icon.
Then I also noticed that there are posts within this forum that appear to have the exact same symptoms. But no one responded, so I wondered if it was a self-solvable problem.

But since I couldn't figure out the cause of the problem by going through the user configuration files, let alone restarting the camera driver, and since purging and reinstalling KStars and INDI Libraries didn't change the situation, I decided to post it here.

I've tried the behavior in various cases, so reading the settings from the Ekos side right after the start fails, and informing Ekos of the settings from the INDI side is working.
I've also replaced 3 ST-7s with CFW8 and the same problem has reproduced itself, and this morning it was the same with a new ubuntu machine. So I was thinking that this was probably something to do with KStars, INDI SBIG CCD Lib, remnants of the old SBIG universal driver, and their relationship to the system.
Then a new build of KStars and an update of the ubuntu kernel arrived, so I tried them one by one and found that on two ubuntu PCs, once I was satisfied with these updates, the situation became normal.

I'm glad we got it resolved.
