gphoto2 --summary outputs (-1 unspecified error)

[xancudo]

Hello,

On PopOS 22.04 using flatpaks for Shotwell, Darktable, and Digikam. All recognize the GoPro 10 Black, but when choosing import, all issue a connection error. They all have libgphoto2-2.5.30 from what I can tell.

Shotwell: Unable to fetch previews from camera, Unspecified error -1

Darktable: Failed to initialize GoPro HERO10 on port xxx,xxx. Likely causes are: possibly locked by another application.

Digicam: Failed to connect to camera. Please check that it is connected and properly turned on.

gphoto2: *** Error ***
PTP General Error
*** Error ***
An error occurred in the io-library ('Unspecified error'): No error description available
*** Error (-1: 'Unspecified error') ***

In Gnome Files, the camera mounts/unmounts properly and shows GoPro MTP Client Disk Volume, and I can access the data OK. I can mount the SD Card independent, and it works OK.

ps aux and found and killed /usr/libexec/gvfs-gphoto2-volume-monitor, repeated the above but that did not resolve the issue.

I compiled ghoto2 2.5.28 and libgphoto2 2.5.30 on both my Pop system, and an Ubuntu non-GUI server vm. Both do the same thing. Attached the GoPro and gphoto2 --list-ports, and --auto-detect show a GoPro HERO10 Black, but --summary issue the above error.

The non-GUI server vm is running on the same Pop box, under VirtualBox, but the GoPro passes to that OK, so it just seems to be a PTP camera thing, unless I didn't compile some important piece in. I did have to go back and add libusb-dev in the process once, for gphoto2 to see USB devices initially. There is a reference to libusb.c in the debug file, but I'm not sure if its related.

gphoto2 --debug detects the GoPro but when it tried to communicate, those fail.

Same here, Ubuntu 24.10 beta. Attaching my logfile:
my-logfile.txt

Suspect the gopro firmware, since the ethernet interface that my gopro also exposes over USB, drops and comes back again as I get the error in gphoto2. Camera firmware 1.30. [EDIT] Same thing after updating to firmware 1.50.

I reported it to GoPro Support, reference number 14498440. I chatted with Michael.
