Fedena 特别需要 Ruby 1.8.7。在任何其他版本的 ruby​​ 上安装 Fedena 都会失败。这些是所需的以下软件版本:

ruby 1.8.7

ruby 1.3.7

rails 2.3.5

您可以使用以下内容来确认版本。对于 Ruby，运行 ruby -v .对于 Rubygems，运行 gem -v对于 rails ，您可以使用 rails -v命令，或 gem list | grep rails .

您的问题源于 Ruby 1.8.* 已从官方 Ubuntu 14.04 存储库中删除，并且您的 Rails 安装正在下载 1.9.1 作为依赖项。

为了让您更轻松，我邀请您设置新服务器并运行 Fedena 2.3 的自动安装程序 here这将安装所需的基本库，之后您应该安装上面的其他 gem，并且您的安装应该可以正常工作。
