does not work with latest Capistrano 3

[JeanMertz]

Should this gem still work with the latest Capistrano 3 versions?

I have the following snippet:

desc 'Run Racksh console'
task :console do
  on primary(:app) do
    within release_path do
      SSHKit.config.backend = SSHKit::Interactive::Backend
      set :pty, true

      execute :rake, :console, "RACK_ENV=#{fetch(:stage)}"
    end
  end
end

when running cap staging console I can see the racksh terminal starting, but no input is possible:

$ cap staging console --trace

any thoughts?

Hmm... try setting SSHKit.config.backend before the on primary and see if that does the trick.
