Have you made sure that the flatpak has the proper permissions to access the tethered camera?

I am not sure. How can I check that?

Get the application "Flatseal" its an easy GUI to inspect the sandbox permissions of a flatpak.

Get the application "Flatseal" its an easy GUI to inspect the sandbox permissions of a flatpak.

It has access to all devices, and copy and import works. But not tethered shooting

Is the camera storage mounted by your desktop environment automatically when it is connected?

Also is your camera supported by libgphoto2?

Yes, as per https://github.com/gphoto/libgphoto2/wiki/List-of-cameras it is.

And I always unmount the camera from the desktop, otherwise darktable won't detect it

[paperdigits]

Alright, how about the first question?

Yes.

Can you unmount it and forbid your desktop from mounting it?

Secondly, if you install gphoto2 and try using it from the command line, does it work?

I can unmount it, but I am not sure how to forbid it.

And yes, yesterday I was messing around with gphoto2 in the command line and the live view feature and taking a picture directly from the command line worked fine.

Same thing with Nikon D7500+DarkTable 4.8.1 (windows10)

I attach debug log (darktable -d camctl) log_20240906_1.txt

NOTE: if I use gphoto2 directly, I can capture images without problems

[robyquin]

I compiled last version from github, and this version also crashes! (Nikon D7500+darktable 4.9.0+421~gdb0990bfed - windows10)

log_20240906_4.9.0+421~gdb0990bfed.txt

[paperdigits]

@robyquin you need to have your DE not mount it, this is from your log:

36,3377 [camera_control] remove Nikon DSC D7500 on port usb:001,011 from ununsed camera list as mounted

[robyquin]

This weekend I did some tests with different settings, Here are log files log:

log_20240906_4.9.0+421~gdb0990bfed_magik.txt log_20240906_4.9.0+421~gdb0990bfed_noCL.txt log_20240906_4.9.0+421~gdb0990bfed_OutofFocus.txt log_20240906_4.9.0+421~gdb0990bfed-dirty.txt log_20240906_4.9.0+421~gdb0990bfed.txt

in this log, I added new log messages to understand the flow of function calls: log_20240907_4.9.0+421~gdb0990bfed-dirty_robyquin-log.txt

An interesting thing, I hope to help you

I had to finish a photographic work, and as a workaround, I used "copy & import from camera" button: It works fine! (I have no log files of this last attempt.)
