When you run update-initramfs you should not be getting error messages for missing skylake drivers.

Under Ubuntu 16.04 LTS:

$ sudo update-initramfs -u
update-initramfs: Generating /boot/initrd.img-4.14.34-041434-generic
Adding /lib/firmware/i915/skl_guc_ver9_33.bin

Under Ubuntu 18.04 LTS:

$ sudo update-initramfs -u
update-initramfs: Generating /boot/initrd.img-4.15.0-20-generic
Adding /lib/firmware/i915/skl_guc_ver9_33.bin

In particular you should be seeing the last line. If not follow the instructions here: Updated kernel to 4.8 now missing firmware warnings
