GitHub - fatal: could not read from remote repository

I'm working on an article regarding Ghost, I came across the following which didn't work:

# First clone Ghost with submodules and make it your working dir
git clone --recurse-submodules git@github.com:TryGhost/Ghost && cd Ghost
https://ghost.org/docs/install/source/#ghost-core
fatal: could not read from remote repository

This assumes that you have a git public key on file. Alternatively, you should be able to use the public URL which would look something like:

git clone --recurse-submodules https://github.com/TryGhost/Ghost.git && cd Ghost
An alternative CLI to clone Ghost from the public repository.
