Bug Description

After my f-spot was not able to download photos from my camera (it already worked) I foudn out that /etc/udev/rules.d/45-libgphto2.rules was missing. Cameras ended up beeing ownd by root.root.

The following command created the file, but this shoudl be done in a post install script.
sudo sh -c "/usr/lib/libgphoto2/print-camera-list udev-rules mode 0660 group plugdev > /etc/udev/rules.d/45-libgphoto2.rules"

i've tried to reinstall (using dpkg -i /var/cache/apt/archvies/libgphoto2*) and trigger postinstall scripts that way, but taht dd not happen (no error was given), I assume the packages are broken.

regards

Starting with Hardy, Ubuntu no longer uses device file ownership to control access to devices like cameras, scanners & memory sticks. Instead the HAL/ConsoleKit/PolicyKit system allows access to the device file for the currently active user by manipulating the ACLs on the device file. See https://wiki.ubuntu.com/DesktopTeam/Specs/HardyHardwareDetection for more info. The expected behaviour is for the device file to be owned by root.root, but if you use "getfacl /dev/bus/usb/BBB/DDD" you should see an Access Control List that grants your username rw- access.

The libgphoto2-2 postinst script now actually runs "/usr/lib/libgphoto2/print-camera-list hal-fdi > /usr/share/hal/fdi/preprobe/10osvendor/20-libgphoto2.fdi"

Having "said" all that, it obviously isn't working properly for you. To help the devs track down the problem, the following info would be useful:

1. The version of the libgphoto2-2 package you have installed

2. With the camera plugged in and switched on, use "lsusb" to find the Bus and Device number the camera is using and then attach the output of "lsusb -vs BBB:DDD" to this bug report (e.g. lsusb -vs 003:005 > lsusb.txt and then attach lsusb.txt)

3. Attach the output of "lshal" to this report.

Okay, sorry for the confusion, the /etc/udev/rules.d is still full of config files and the libgphtot2 package contains an empty /etc/udev/rules.d directory.

Thanks for reporting this bug and supporting information. I think this bug now has enough information for a developer to look at it so I'm marking it as "confirmed" to let them handle it from here. Thanks for taking the time to make Ubuntu better!

Rasmus, your bug with gthumb is bug 287689 which was fixed in an update for 8.10.

iroli, jesse, do you still have this problem on current 8.10 plus updates or 8.04 plus updates? If so, please give me the output of "ck-list-sessions" and again the getfacl /dev/bus/whatever/it/is/for/you in a Terminal after you plugged in the camera. If ck-list-sessions is empty, and thus you didn't get an ACL. then it is a ConsoleKit problem.

If you did get an ACL, but photo import fails, then please install the "gphoto2" package, say "Unmount" in the dialog which pops up after plugging in a camera, and do in your Terminal:

gphoto2 --debug --debug-logfile /tmp/gphoto.debug.txt -L

to get debugging information. Please attach /tmp/gphoto.debug.txt here.

Thanks!
