git ssh：权限被拒绝（publickey）
我尝试使用github，所以我按照帮助文档。 但是当我使用这个命令时： ssh -vT git@github.com我得到的错误是这样的：

代理人承认使用钥匙签名？ 没有更多的validation方法可以尝试？
有人可以解释这里有什么问题吗？
谢谢。
搜索谷歌“代理商承认无法使用密钥签名”。 建议退出当前会话然后重新ssh-add ，或者使用ssh-add应该可以解决问题
理由： Ubuntu使用ssh-agent程序：
ssh-agent is a program to hold private keys used for public key authentication (RSA, DSA, ECDSA). The idea is that ssh-agent is started in the beginning of an X-session or a login session, and all other windows or programs are started as clients to the ssh-agent program. Through use of environment variables the agent can be located and automatically used for authentication when logging in to other machines using ssh(1).
如果您刚刚生成密钥，则ssh-agent不知道它，因此无法使用密钥进行签名 – 这正是错误消息所说的内容。
要添加密钥，您需要重新启动ssh-agent （即注销并重新登录）或使用ssh-add重新扫描密钥。
有关详细信息，请参阅man ssh-add和man ssh-agent
你有没有正确设置git和ssh键。 如果没有看到这里 。
取自github ：
当ssh找不到您的密钥时，也可能导致此问题。 确保您的密钥位于默认位置
~/.ssh。 如果再次运行ssh-keygen并在所有3个提示中按Enter键，它将自动放在此处。 然后，您可以将id_rsa.pub的内容添加到您的帐户。 如果id_rsa.pub不起作用，请尝试id_dsa.pub。 如果您只有rsa密钥，则可能需要使用ssh-keygen -t dsa生成新的dsa密钥。
PS有时URL输入错误。 URL区分大小写。 确保正确输入。
也看到了这一点 。
使用github-keygen进行Github的SSH设置：简单，强大，安全和安全（比官方文档推荐的更安全）。
