I would recommend against using UKUU (or manually installing vanilla kernels) on Ubuntu LTS versions. It can cause hard to diagnose problems and really runs counter to the purpose of LTS versions (which is stability). If you want bleeding edge, better use the regular release. Ubuntu 17.04 is already on kernel 4.10.This app for Linux will tell you which kernel is available in Ubuntu. I use it in Mint and presently on kernel 4.10.12 which have full support for Kaby Lake.
