我有一个新应用程序，我正在尝试提交到我的 git 帐户。我似乎无法提交：
$ git push origin master
Permission denied (publickey).
fatal: The remote end hung up unexpectedly
$ ssh -T git@github.com
Permission denied (publickey).
$ ssh-add -1
Could not open a connection to your authentication agent.
检查我的 SSH 时，我收到此错误：
$ ssh -vT git@github.com

我有一个 GIT 帐户，我有他们的本地客户端，并且我有一个附加的 SSH 密钥，其中创建了 id_rsa.pub 文件，我创建了我的全局用户设置，我在 GitHub 中创建了一个存储库，我在 Cygwin 中有所有相关的 SSH 代理安装后，我在安装 Cygwin 和使用终端时禁用了所有防火墙产品。
我唯一可以解决的问题是：
$ ssh-keygen -lf ~/.ssh/id_rsa.pub
/home/Fletch/.ssh/id_rsa.pub: No such file or directory
但是，我创建了这个文件并在我的帐户中看到了 SSH 密钥。我搜索了所有类似的帖子，似乎找不到问题。
