Question

I am following the instructions on github for forking a repo but everything up to not including configure the remotes works. I am told to run the following code but git fetch upstream returns the following fatal: The remote end hung up unexpectedly
Whats causing this, and could someone explain what it means to configure the remotes.

$ cd Spoon-KnifeChanges the active directory in the prompt to the newly cloned "Spoon-Knife" directory
$ git remote add upstream git://github.com/octocat/Spoon-Knife.gitAssigns the original repo to a remote called "upstream"
$ git fetch upstream

Answer 1

Why not just start fresh:

$ rm -rf Spoon-Knife
$ git clone git://github.com/octocat/Spoon-Knife.git
$ cd Spoon-Knife
$ git remote add upstream git://github.com/octocat/Spoon-Knife.git
$ git fetch upstream

As for the remote end hung up unexpectedly error, see this Stack Overflow question (among many) — most likely reason is that your SSH keys weren’t set up correctly.
