Upgrading Moodle

I am using this link to upgrade a 1.9.14 server to 2.2:

http://docs.moodle.org/22/en/Git

this works:

$ git clone git://git.moodle.org/moodle.git                       (1)
$ cd moodle
$ git branch -a                                                   (2)
$ git branch --track MOODLE_22_STABLE origin/MOODLE_22_STABLE      (3)
$ git checkout MOODLE_22_STABLE                                    (4)

When I get here:

$ cd /path/to/your/moodle/
$ git pull

I get an error: No remote repositories specified. Please, specify either a URL or a remote name from which new revisions should be fetched.

git remote -v returns nothing.
