How to include link in my Debian 9 (Stretch) sources.list?
I need to include with contrib non-free as well.
I need to explain why too, because the URLs of sources.list (/etc/apt/sources.list) are nothing like the FTP mirror online.
Example:
URL: http://ftp.br.debian.org/debian/dists/stretch/non-free/
sources.list [Not sure, just an example even]: deb-src http://ftp.br.debian.org/stretch stretch main contrib non-free
What is the correct way to include the Brazilian mirror of Debian 9?
