git - 无法通过ssh连接到github

Question

我试图从我新安装的运行带有 fluxbox 的 manjaro 的 linux 机器上克隆我在 github 上的一个存储库。我设置了 user.name 和 user.email 并上传了正确的 ssh key 。但我总是得到

The authenticity of host 'github.com (192.30.252.129)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
Are you sure you want to continue connecting (yes/no)? 
Host key verification failed.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository exists.

我在谷歌上搜索了一下，发现我应该执行 ssh-keygen -R github.com 这应该从我的 known_hosts 文件中删除 github 但 known_hosts 文件甚至还不存在，因为我刚刚完成设置新的 Linux 安装。

所以我尝试了 ssh -vT git@github 这给了我

ssh -vT git@github.com

这让我难以理解。谁能告诉我出了什么问题，也许如何解决这个问题？

Answer 1

您是否尝试将 github 添加为已知主机？

如果您有一个现有的 known_hosts 文件并且不想覆盖(正如@Puce 在评论中建议的那样)，请使用它。

ssh-keyscan -t rsa github.com >> ~/.ssh/known_hosts

这会将 rsa key 添加到 known_hosts 的末尾。

如果您不知道known_hosts 是什么/意味着什么，或者您从未确定使用它，您可以简单地编写一个新的，但请注意，如果您有，这将删除现有的任何。

ssh-keyscan -t rsa github.com > ~/.ssh/known_hosts
