I want to install the Intel Linux Graphics Drivers through the program, but everytime I've tried to install them this error comes up

W:GPG error: https://download.01.org Ubuntu Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 8D8847D52F4AAA66
W:Failed to fetch http://ppa.launchpad.net/openshot.developers/ppa/ubuntu/dists/raring/main/binary-i386/Packages  404  Not Found
E:Some index files failed to download. They have been ignored, or old ones used instead.

How do I fix this; I really want to install this so I can play games from Steam.

Processor: Intel® Celeron(R) M CPU 440 @ 1.86GHz
Graphics: Intel® 945GM x86/MMX/SSE2
32-bit Ubuntu 13.04

Run these commands in a terminal (Ctrl+Alt+T)

wget --no-check-certificate https://download.01.org/gfx/RPM-GPG-KEY-ilg -O - | \
sudo apt-key add -
wget --no-check-certificate https://download.01.org/gfx/RPM-GPG-KEY-ilg-2 -O - | \
sudo apt-key add -  

(source)

Then retry

sudo apt-get update
sudo apt-get --reinstall install intel-linux-graphics-installer

Then run the installer again
(source)

  • @bad_charge This is unrelated to Intel Linux Graphics, just try the next commands in my answer. Those errors are for the openshot.org video editor

You can make ubuntu download the missing key it is complaining about.

In your case: ... the public key is not available: NO_PUBKEY 8D8847D52F4AAA66 copy the hash from error message 8D8847D52F4AAA66

$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 8D8847D52F4AAA66
$ sudo apt-get update

It should not complain anymore.
