Can't get photos from camera -

gphoto2 is giving me the following error messages. I used it a few days
ago with a different camera and it worked without a hitch.

Any suggestions appreciated.

I have the same problem. I found a fix that worked, then probably after
one of the updates or for whatever reason it didn't work anymore. Here's
the fix anyway:

You must have a file /etc/udev/rules.d/90-libgphoto2.rules

To create one, as root

cd /usr/lib/libgphoto2
./print-camera-list udev-rules version 0.98 mode 666 owner root group
users > /etc/udev/rules.d/90-libgphoto2.rules # one line.

This used to work. Now, however, it doesn't anymore. I guess a system can
use one of several methods for hot-plug devices, and the fix above is for
udev. If I run gthumb-import manually at the prompt, I get this error
message:

process 2809: arguments to dbus_message_new_method_call() were incorrect,
assertion "_dbus_check_is_valid_path (path)" failed in file dbus-
message.c line 1074.
This is normally a bug in some application using the D-Bus library.
D-Bus not built with -rdynamic so unable to print a backtrace


which I is about D-Bus, or maybe it's a problem with gthumb-import using
D-Bus. I don't pretend to understand how D-Bus works, and how it
interacts with udev, but perhaps the fix should be related to d-bus.
Maybe someone can shed some light here.

I did as you describe and it did create
/etc/udev/rules.d/90-libgphoto2.rules.

However I borrowed the camera from my grandson and don't have it to test
with now.

I was panicing because I wanted the photo of the VIN on a car I need to
register and ran out of time to do that yesterday. My daughter
extracted the files on her Mac this morning and I made the desired copies.

So it's a non-problem until the next time.

By the way I should have mentioned this computer runs F-7.

Thanks for the help.

Strange. I don't remember having this issue in F7, but I may be wrong.
The only way for me to download the images from the camera is with a usb
card reader.

It occurred to me that last week when I got photos from my daughters
camera she gave me the memory card, reader, and cable. That worked
without difficulty.

Last time I used gphoto2 might have been FC-5, whatever, it worked
well then. I may not need it for another year.
