Puppet-apt submodule repository is not found

[LauraHornbake]

Cloning this repo with --recursive flag fails with "Clone of 'git://github.com/camptocamp/puppet-apt' into submodule path 'puppet/modules/apt' failed".

Same problem here, the repository was removed from github.
I used the following as a work around:

cd piwik-dev-environment
git clone git@github.com:puppetlabs/puppetlabs-apt.git puppet/modules/apt
for i in *; do git submodule update $i; done
