You need to use a text editor such as
nano to modify this file:
Code:
/etc/apt/sources.list
If you are unfamiliar with nano:

nano:
Use the Arrow keys to move the cursor within the file.
^ means Ctrl key.
^O…..Save (“Write Out”) ..........Ctrl + O (then press Enter)

To
install nano (if it is not installed already), open a Terminal and give the following commands:
Code:
sudo apt-get update
Press Enter and give your user password (not root password) when prompted (not displayed for security). Press Enter again.
Code:
sudo apt-get install nano
Press Enter.
Open file:
Code:
sudo nano /etc/apt/sources.list
Your
modified file will look something like this after you have
added the text in bold type:
Code:
deb http://httpredir.debian.org/debian jessie main contrib non-free
#deb-src http://httpredir.debian.org/debian jessie main contrib non-free
deb http://httpredir.debian.org/debian jessie-updates main contrib non-free
#deb-src http://httpredir.debian.org/debian jessie-updates main contrib non-free
deb http://security.debian.org/ jessie/updates main contrib non-free
#deb-src http://security.debian.org/ jessie/updates main contrib non-free
Save the modified file (Write out) using Ctrl and O. Press Enter.
Then
Exit (press Ctrl and X).
In Terminal:
Code:
sudo apt-get update
Add the R9 200 drivers:
