Ubuntu – Intel Linux Graphic Drivers

graphicsintel graphics

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: IntelĀ® Celeron(R) M CPU 440 @ 1.86GHz
Graphics: IntelĀ® 945GM x86/MMX/SSE2

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 -  


Then retry

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

Then run the installer again
