"git pull" does not work. "git fetch" does, but it does update all
references?

You don't want to pull because that involves merging, which doesn't make
sense. A git-fetch is what you want, and you can use wildcards to make
sure you get all of the refs. The default is something like this:

[remote "origin"]
  url = git://git2.kernel.org/pub/scm/git/git.git
  fetch = +refs/heads/*:refs/remotes/origin/*

However, if you are intending to make this an _exact_ copy of Junio's
(because you will be fetching from it with your other, non-bare repos),
then you probably don't want the "separate remotes" layout. You want to
copy the refs with the same names:

[remote "origin"]
  url = git://git2.kernel.org/pub/scm/git/git.git
  fetch = +refs/heads/*:refs/heads/*

The "+" in both cases means that it copies whatever Junio has, even if
it might lose some commits of yours. But that seems to be what you want
in this case.

I also would like to check that it is impossible to push anything to the
repository.

The simplest thing is not to give write access to the repo for your
pushers. However, you could also put in a pre-receive hook that rejects
all pushes.
