cap deploy:cold fails with 'No such file or directory - git rev-parse master' error

I am trying to deploy my rails application for the first time.

Server is running Ubuntu 10.4 server (64bit)

Local machine is running Windows XP.

Repository is at github

I have successfully run

cap deploy:setup

but when I run

cap deploy:cold

I get the following error:

D:\Rails\rails_apps\fx>cap deploy:cold

Here is my 'deploy.rb' file

set :application, "fx"  #"pragmaticriskmanagement.gotdns.com"
set :repository,  "git@github.com:jmedding/Fx.git"
set :deploy_to, "/var/www/#{application}"

set :git_enable_submodules, 1         # Make sure git submodules are populated

set :location, "pragmaticriskmanagement.gotdns.com"

set :user, "xxxxx"
set :use_sudo, false

set :scm, :git

role :app, location #"your app-server here"
role :web, location #"your web-server here"
role :db,  location,    :primary => true #"your db-server here", :primary => true

namespace :deploy do
    desc "Restart Application"
    task :restart, :roles => :app do
      run "touch #{current_path}/tmp/restart.txt"
    end

    desc "Make symlink for database.yml" 
    task :symlink_dbyaml do
      run "ln -nfs #{shared_path}/config/database.yml #{release_path}/config/database.yml" 
    end

    desc "Create empty database.yml in shared path" 
    task :create_dbyaml do
      run "mkdir -p #{shared_path}/config" 
      put '', "#{shared_path}/config/database.yml" 
    end
end

  after 'deploy:setup', 'deploy:create_dbyaml'
  after 'deploy:update_code', 'deploy:symlink_dbyaml'

  after "deploy", "deploy:cleanup"

and now I'm stuck...

Any help would be greatly appreciated.

Thanks,

Jon


Sorry to resurrect such an old thread, but I solved this by adding the default location of my git binaries (C:\Program Files (x86)\Git\bin) to my PATH variable.


Ok, I have made some progress.

It seems that the error indicates that the git ls-remote command could not be found on the local system (win xp). As a test, I opened the GIT Bash shell and tried the command - it worked. Next, I tried

cap deploy 

from the GIT Bash shell. Command not found. OK, I added my rails path

D:\Rails\ruby\bin

to the windows 'path' variable. Now, try

cap deploy

from the bash shell. This seems to have solved this problem, which now leads to my next problem

** [xxxxxxxx.com :: out] Cloning into /var/www/fx/shared/cached-copy...
** [xxxxxxxx.com :: err] Permission denied (publickey).
** [xxxxxxxx.com :: err] fatal: The remote end hung up unexpectedly

I can successfully run cap deploy from my linux box with the same public key. Also, I can push to my Github repo from this laptop with this key. Of course, the key in question should be on the server, but if it works when I run 'cap' from the linux box, why wouldn't it run from here?
