The git repositories have moved
We’ve renamed our ‘org’ on github.com, so the new URLs are
and so forth (instead of github.com/NewDreamNetwork). You can update your git remote with something like
git remote set-url origin firstname.lastname@example.org:ceph/ceph.git
(if you are a github user), or
git remote set-url origin git://github.com/ceph/ceph.git
if you cloned anonymously.
