so Update Manager said I could update from 6:3.6.1+202210191503 up to 6:3.6.1+202210271233 -- did the update but no joy, same driver crashes.
I removed-and-reinstalled, no joy.
I used synaptic to completely remove all kstars and indi and data, then reinstalled from ppa. no joy.
I even installed from snap......guess what? no joy.
Next, I completely removed everything again, and installed with synaptic from ppa.....kstars-bleeding and indi-full. It seemed to take a LOT longer than apt-get in a terminal. Still won't run: "webacm driver failed to start" over and over. Looks like synaptic didn't install indi-webcam, so I installed it.
Now it runs, up to the point where indi control panel shows "Exposure" -- for a couple of seconds, then it all crashes and ekos and kstars both disappear.
The only entry I've ever seen that even looks like a real error is "Driver indi_webcam_ccd: Impossible IPState 4""
