linux – Debian: deb command not found. How can i fix it?
The instruction is
Add contrib and non-free components to /etc/apt/sources.list, for example
I.e., youre 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
I hope this helps
