iPhone/iPad contents are inaccessible

[Sadi Yumuşak]

1) System: Ubuntu 16.10 "Yakkety" 64-bit

2) Package: libimobiledevice6 (Source: libimobiledevice) Version: 1.2.0+dfsg-3ubuntu1

3) What is expected: When an idevice (iPhone, iPad, etc.) is connected via a USB port, first a "Trust / Don't Trust" prompt appears on the idevice, and after selecting "Trust", either a prompt appears on the computer asking the user what to do and/or a nautilus window opens to show accessible contents of the device, e.g. photos and/or videos taken by its camera.

4) What happens: It looks as if everything is in order, but the nautilus window opened is empty! In other words, system cannot access the device properly and show the contents of the appropriate folder.

After upgrading from Ubuntu 16.04 to Ubuntu 16.10 (personally had to do a fresh install after persistent system upgrade problems), it's no longer possible to transfer photos from iPhone or iPad.

The Tust prompt appears with audio echoed, probably as a result of "double (or even triple) connection":

1 - It seems the idevice begins charging successfully as everything looks OK in the power indicator.

2- Nautilus seems fully aware of the idevice displaying everything as normal, even opening a folder window seen normally, but it just cannot show the actual location including the photos.

3- I think somehow the idevice is also detected as an ethernet thing.

I tried a recommended solution using ifuse, which required these packages: ideviceinstaller python-imobiledevice libimobiledevice-utils libimobiledevice6 libplist3 python-plist ifuse

I properly implemented the required configuration, but the ifuse command merely resulted in this error message:

GnuTLS error: Error in the pull function.
Failed to connect to lockdownd service on the device.
Try again. If it still fails try rebooting your device.

So I thought probably the new libimobiledevice package went back to an earlier state on this where Apple's "Trust / Don't Trust" prompt cannot be handled properly.
