我尝试使用 github,因此我遵循了帮助文档。但是当我使用此命令时:我收到如下错误:ssh -vT [email protected]
jacos@Jing:~/.ssh$ ssh -vT [email protected]

代理是否同意使用密钥进行签名?没有其他身份验证方法可以尝试?
有人能解释一下这里出了什么问题吗?
谢谢。
答案1
在谷歌上搜索“代理承认未能使用密钥签名。”建议退出当前会话然后重新登录,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).
如果您刚刚生成了一个密钥,ssh-agent
但对此并不了解,因此无法使用该密钥进行签名 - 正如错误消息所说的那样。
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。
请参阅man ssh-add
并man ssh-agent

使用github-keygen
为 Github 设置 SSH:简单、强大、安全且可靠(比官方文档推荐的更安全)。
