The assistant does not allow adding an existing repo: I tried to add a "remote server", to enter the credits, and then I add to choose between "git-annex" or "rsync". Choosing "git-annex" tries to create a new repo and then fails. The repo on the server is a bare one, accessed via gitolite. Setting the remote manually ("git remote add origin git@example.org:my-annex.git" works (I can pull, push, ...))

The following is the set of steps I use when setting assistant up on a new repository:
Entering the folder path now lets the assistant take over.
For an existing repository:
Not sure if this would be helpful for working out what the assistant behavior should be, but maybe it'll help others get to the point where the assistant works with a gitolite managed repo.
