Intel Graphics Update Tool for Linux* OS v2.0.2 is unable to update graphics drivers

Question

I downloaded the intel graphics tool for updating drivers and got following error:

Ensuring consistent system... OK
Listing packages... OK
Setting up repositories... OK
Installing packages...
    Updating package cache... Failed

Error details:

W:GPG error: https://download.01.org/gfx/ubuntu/16.04/main xenial InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 56A3DEF863961D39

Does anyone know how to fix it?

Thanks,

Solution

Ubuntu 16.04 comes with fairly updated Intel Graphics drivers. There's little, if anything, to gain from the minor revision updates the Intel PPA has to offer.

That said, if you still want to use the tool then you should follow all the instructions at the download's page, namely

1. Signatures - Ubuntu:

   wget --no-check-certificate https://download.01.org/gfx/RPM-GPG-KEY-ilg-4 -O - | \ sudo apt-key add -

2. sudo apt update && sudo apt full-upgrade

No need to run the graphical installer again.

Additional info (off-topic): Remove the Ubuntu Tweak PPA because it's not for 16.04. Search for a repackaged UT installer for xenial (deb) instead.

Yes, I would stay away from using the Intel Graphics Update Tool. Nothing but problems, especially if you later decide to uninstall it. Maybe others can chime in with their experiences. Cheers, Al
