公钥被拒绝，但 ssh 密钥被接受

Question

当我 git push 收到错误时，我无法推送到 git（或者更确切地说，git 对我有问题）：

Permission denied (publickey).
fatal: The remote end hung up unexpectedly

为此，我查看了 git 的 help page，但他们建议的所有“测试”都通过了，包括通过运行 $ ssh -vT git@github.com 检查是否使用了正确的密钥。根据我在 SO 上看到的帖子，这似乎是大多数人搁浅的地方，但它对我有用。这是我遗漏的情况下的输出。

这是.git/config中的远程URL

[remote "origin"]
    url = ssh://github.com/[user]/[repo].git
    fetch = +refs/heads/*:refs/remotes/origin/*

Answer 1

您的 git 配置缺少用户，因此 git 尝试以您 (charliekim) 的身份进行身份验证，而不是作为 Github 期望的用户 git。

使用正确的用户，你应该可以连接：

[remote "origin"]
    url = ssh://git@github.com/[user]/[repo].git
    fetch = +refs/heads/*:refs/remotes/origin/*
