exactly the same result for me.
... by downloading and installing the *.deb
https://download.01.org/gfx/ubuntu/16.04/main/pool/main/i/intel-graphics...
running intel-graphics-update-tool and finishing the installation.
sudo apt-get update
results in Warnings due to missing key 56A3DEF863961D39

Thx!
Although the key is now known, please move forward to sha256, it's 2016...

Hi !.
Yes please change the SHA1 because every time when I update synaptic on Ubuntu I have this error alert :

Great! 16.04 packages are on the repo, however, they're signed with a different unavailable key, again:
