Intel Graphics Updater - "Updating package cache... Failed" (Ubuntu 16.10)

Question

I'm having trouble updating Intel drivers with the Intel Graphics Update Tool v2.0.3.

And this is the error window:

I'm using an XPS 13 FHD with an i5-6200U and Intel® HD Graphics 520 (Skylake GT2), running Ubuntu 16.10.

The repository for the Intel Graphics Installer for Linux requires a gpg public key. From https://01.org/linuxgraphics/downloads/intel-graphics-update-tool-linux-os-v2.0.3, we see that we need to add this gpg public key. Enter the following commands in terminal...

wget --no-check-certificate https://download.01.org/gfx/RPM-GPG-GROUP-KEY-ilg

sudo apt-key add RPM-GPG-GROUP-KEY-ilg

To solve the lists defined multiple times, again, in terminal...

ls -al /etc/apt/sources.list.d/arc-theme.list*

You'll probably see something like this:

arc-theme.list
arc-theme.list:1
arc-theme.list:2
arc-theme.list:3

We want to delete all but the first one:

sudo rm /etc/apt/sources.list.d/arc-theme.list:1
sudo rm /etc/apt/sources.list.d/arc-theme.list:2
sudo rm /etc/apt/sources.list.d/arc-theme.list:3
