The ref that gerrit uses for drafts changed between their release
candidate and final release, which was right about the time some distros
imported the then-current release of git-review.  In short, you can fix
that by upgrading git-review.  You can get the latest version (currently
1.20) at:


Which will correctly send that to "refs/drafts/master...".

It should not be, that operation generally takes a few seconds at most.
First, I'd make sure that you aren't using any ssh connection caching
which does not work with Gerrit's internal ssh server (if you haven't
set ControlMaster or ControlPath, you're not using it which is good).
Then, try running:

  ssh -vv -p 29418 jean-marc-saffroy at review.openstack.org gerrit ls-projects

To see if there are any obvious errors or where the slow part might be.
If you're still having trouble, hop on to #openstack-infra on Freenode,
and we can help you with real-time interactive debugging.
