How to tranfer files between iPhone and Ubuntu?

How to transfer files between my Ubuntu and iPhone?

The answer here recommends to use this URL in nautilus:

afc://<your iPhone's UDID>/

Then next question is:

What is my iPhone UDID (without using iTunes)?

The answer here recommends running the following code:

lsusb -v 2> /dev/null | grep -e "Apple Inc" -A 2

and the result looks like this:

iManufacturer           1 Apple Inc.iProduct                2 iPadiSerial                 3 7ddf32e17a6ac5ce04a8ecbf782ca509...

So a URL like this

afc://7ddf32e17a6ac5ce04a8ecbf782ca509.../

Must work in nautilus. While it does not. where am I making mistake?

(... are filled with proper part of UDID)

Please do not recommend me to install iTunes on Ubuntu. No matter what method you use either Wine or PlayOnLinux it cannot work with USB.

Please also consider that the package gvsf-backends cannot be located on Ubuntu 16.04.1 LTS . I am using iPhone 7.
