capistrano problem

I am having a problem with deploying my application to my server.

I have msysgit, github and capistrano installed and working.

  • Change branch that is switched to after deploying
  • Excluding files from being deployed with Capistrano while still under version control with Git
  • Git: Merge a branch but without some of the files I only need modified locally?
  • Capistrano 3 deploy WordPress with GIT available in release dir
  • Fatal: could not read Username for '': No such device or address
  • Using capistrano to deploy from different git branches
  • I have successfully pushed my app to github and can successfully run
    cap deploy:setup to setup on my server from my local machine.


    When I run cap deploy:cold it asks me for my passphrase to connect to
    github repo then it asks it again to connect to my server but then it
    gives me an error permission denied (public key) and rools back.

    It seems like this is an error with my keys but how can it then
    connect to my server to do the cap deplo:setup ?

    My public keys are the same in both github and my server is this
    correct ?

    Also when running cap deploy:setup it asks me for my user server
    password is this correct ?

    Please help as this has delayed me for days already

    This is the error:

    Thanks alot rick

    If I add this to my deploy.rb file

    set :ssh_options, {:forward_agent => true}
    on :start do    

    I get this different error

    You should have on your server (where you want deploy) installed yours access keys for git server.

    You should have yours key files (with chmod 600):


    in ~/.ssh directory (with chmod 700) on server in deploy user home

    you probably have that keys only on your local development computer.

    You can add for your deploy file hook for ‘setup:cold’ where will be automated
    upload of your local keys files.

    This question is really old, but I just encountered the same problem again on a windows 7 machine. You should add forward_agent and the location of your ssh key to your deploy config file: Here is my fix at config/deploy.rb:

    set :ssh_options,   :forward_agent => true 
    set :ssh_options,   :keys => %w(c:/Users/USERNAME/.ssh/id_rsa)

    Besides that, the best solution would be to develop rails applications (and to use capistrano) in a linux environment. This would avoid tons of such tricks, wordrounds and it would save plenty of time 🙂

    It’s not needed to have the ssh keys to access the repository server on the deploy mahcine. You can activate the SSH forward_agent, to make the ssh_agent follow you from machine to mache. To do this with capistrano, you can add this line to the deploy.rb file

    ssh_options[:forward_agent] = true
