我在VirtualBox下在Ubuntu 10上设置了Rails。除了Github之外，我已经设法配置了几乎所有东西。
每当我尝试ssh git@github.com时，我都会收到一条消息，告诉我permission denied (publickey)。以下是调试后收到的消息：

有人可以帮忙告诉我我做错了什么。还要注意我是Ruby和Git / Github的新手。

Github上有关于此的说明。您需要找到您的ssh公钥（最有可能位于您的~/.ssh文件夹中）并将其上传到Github。
查看您的帐户设置，然后是SSH公钥，然后点击右侧，点击“需要公钥帮助”链接，它将take you here。
