ruby-on-rails - 无法使用 Capistrano 3.2.1 部署到远程服务器。验证 git repo 时出错

Question

我在使用 Capistrano 3.2.1 将 Ruby on Rails 4.0.4 应用程序部署到我的 digital ocean 应用程序、Web 和数据库服务器时遇到 SSH 身份验证错误。 SSH key 已添加到 bitbucket。

当前堆栈:* Chef 11* 伯克谢尔夫 2.0.13* rails 4.0.4* ruby 2.1.0* 卡皮斯特拉诺 3.2.1* Bitbucket.org 上的 repo 协议(protocol)* DigitalOcean 应用程序/网络服务器和数据库服务器

使用 cap production deploy 部署 Capistrano 时出现以下错误:

设置 SSH key 以连接本地和远程存储库(使用 ssh -T git@bitbucket.org 测试)。这是远程服务器上 ssh -v git@bitbucket.org 的输出:

为什么我无法在部署时验证和连接到 bitbucket？有什么想法吗？

非常感谢您的帮助!
