I'm searching answers to sync iTunes 12.5.5 (pictures and musics) on Ubuntu 16.4. I have itunes on my iphone 6s. Which are possibilities that I can try?
Because Apple doesn't provide iTunes for Ubuntu or Linux in general, you can try to install iTunes using wine or PlayOnLinux. Alternatively you can also create a virtual machine using VirtualBox running Windows and use iTunes in there.
