Capistano部署：更新失敗git克隆

Question

我想部署與Capistrano更新，我得到下面的錯誤。爲什麼這會失敗？我之前已部署到此服務器。我已經包含了我的deploy.rb文件。

failed: "sh -c 'git clone -q --depth 1 git@github.com:username/sample_app.git /var/www  
/apps/sample_app/releases/20120518162414 && cd /var/www/apps/sample_app/releases/20120518162414 && 
git checkout -q -b deploy 1eac914d3b04039b8286416f51b4f223b626b267 && (echo

set :application, "sample_app"

set :deploy_to, "/var/www/apps/#{application}"

set :location, "server.domain.com" 

# setup some Capistrano roles 
role :app, location 
role :web, location 
role :db, location, :primary => true 

after 'deploy:update_code', 'deploy:symlink_db' 

namespace :deploy do 

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

desc "Symlinks the database.yml" 
task :symlink_db, :roles => :app do 
run "ln -nfs #{deploy_to}/shared/config/database.yml #{release_path}/config/database.yml" 
end 

end
