NO_PUBKEY A902DDA375E52366

Ubuntu Intel video card repository at requires a custom public key imported before you can proceed. The usual error method you will be getting is like this:

W: GPG error: trusty InRelease: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY A902DDA375E52366

To fix this issue do the following:

sudo apt-key adv ––keyserver ––recv-keys A902DDA375E52366


Rember it’s dash-dash (––) in command line.

It should be fixed. For reference, I am including full log:
