Github权限被拒绝(publickey)不提供shell访问

Question

我试图在我从git hub克隆的文件夹中运行此命令：

git submodule update --init --recursive

然后我收到错误消息，说权限被拒绝(Publickey Key)，我尝试搜索并运行下面的注释来创建ssh密钥：

ssh-keygen -t rsa -C "xxx@xxx.com"

并通过网站添加了ssh key，并运行以下命令查看是否修复：

ssh -T git@github.com

但它告诉我，我已经成功地进行了身份验证，但是GitHub没有提供外壳access.Then，所以我运行以下命令进行调试：

ssh -vT git@github.com

下面是输出：

有人知道怎么解决这个问题吗？非常感谢!

Answer 1

我在帖子中运行了第一个命令：git submodule update --init --recursive，但它仍然告诉我Permission denied (publickey)

这取决于子模块的URL，您可以在存储库的.gitmodules文件中读取该子模块。

或者，它可以依赖于一个子模块的子模块的URL，但如果没有克隆任何子模块，如果错误立即显示，则问题应该仅限于直接的第一级子模块。

因此，请仔细检查.gitmodules文件中的url:其中一个可能引用了您的身份验证无法访问的私有存储库。

Answer 2

这很好，不是错误。

这意味着您的密钥有效，并且您应该能够使用git命令访问您的存储库。

即使git使用ssh协议和登录机制，您也不能在Github的服务器上通过ssh进入一个完整的shell会话。但不管怎样，你不需要它。
