deb http://eddie.website/repository/apt stable main

This is not a terminal command, it's the syntax of apt.
What is retarted is that debian maintainers didn't make it a command, which could take the arguments
as input and place them it /etc/apt/sources.list.

So you will have to do it manually.
echo "deb http://eddie.website/repository/apt stable main" >> /etc/apt/sources.list
apt update
