Puppet started failing on zirconium on 2015-02-16 10:59:33 due to:
Error: /Stage[main]/Role::Transparency/Git::Clone[wikimedia/TransparencyReport]/Exec[git_pull_wikimedia/TransparencyReport]/returns: change from notrun to 0 failed: /usr/bin/git pull --quiet returned 1 instead of one of [0]
a quick debugging showed during git pulling the repo, a username/password is required. Obviously puppet does not provide one and git pull returns with an error code and puppet is complaining
