Capistrano deploy not finding private github repo (key forwarding working)

Question

My capistrano script cannot connect to my github private repository.

here is some of my deploy.rb file:

set :scm, :git
set :repository,  "git@github.com:ohenrik/imagesite.git"
set :ssh_options, { :forward_agent => true }

set :deploy_to, "/home/rails/apps/#{application}"

I have tested agent forwariding on my server and it seems to be working (i can get authorised by github without password or other ssh keys installed).

I think I have the right repository address now, but I'm not sure.

Edit, I get this output:

The scrip hangs on the last line.

Try clearing out the old cached copy -- if you changed the git repository in deploy.rb, Capistrano doesn't automatically update the repository in the cached copy on the server.

$ ssh {production server}
$ rm -rf /home/rails/apps/imagesite/shared/cached-copy
$ exit
$ cap production deploy
