我有一个 Ruby On Rails 应用程序已经运行了大约 9 个月。生产环境是使用 Apache 和 Passenger 的 Ubuntu 服务器。我使用 Capistrano 进行部署，并且使用我的 Git 存储库运行良好。我刚刚更改了开发机器，现在当我尝试部署时出现超时错误。我不确定错误在哪里，但我觉得这可能是某种安全性。我的开发机器是 ubuntu 12.04 桌面。'cap deploy' 的终端输出如下：
* executing `deploy`
* executing `deploy:update`
** transaction: start
* executing `deploy:update_code`
updating the cached checkout on all servers
