How to fully install Intel Graphics drivers on Ubuntu 16.04?

Question

linux

Looks like it's not ready yet, already rebooted twice...
It is written in the screenshot: if you previously ran the updater in this session and made changes, you may still need to reboot the system for them to take effect.

I wanted to update packages from intel, but it says: installation of unreliable packages is required, how?

Then I wrote sudo apt update in the terminal, and I saw there are errors, how to solve this problem?
