I am trying to install graphics card Nvidia Geforce 660 on my desktop. Os: debian 8.
Here is the wiki which gives guidelines : https://wiki.debian.org/NvidiaGraphicsDrivers#jessie-304xx
But as soon as I am on the first step:
deb http://http.debian.net/debian/ jessie main contrib non-free
bash: deb: command not found
How can I install deb?
The instruction is
Add "contrib" and "non-free" components to /etc/apt/sources.list, for example
I.e., you're supposed to add that line to the given file with a text editor. You are not supposed to execute it on a command line.
You can also install the software-properties-common package:
sudo apt-get install software-properties-common
Afterwhich you can run the command below:
sudo add-apt-repository "deb http://http.debian.net/debian/ jessie main contrib non-free"
You can confirm that the repository was added to the list of repositories using this command:
sudo nano /etc/apt/sources.list
That's all.
I hope this helps
