【问题描述】：
我知道这是一个常见问题，但是，即使在花了一个小时查看线程之后，我也无法找到解决方案，因此在此处发布。基本上，在运行git clone 时，我收到以下错误：
Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
我的 .ssh 目录中确实有一个 id_rsa 和一个 id_rsa.pub，并且密钥与我在 github 上以及 ssh 密钥部分下的密钥匹配。所以这不是问题。但是，我意识到我没有 id_dsa 文件或任何其他文件（除了 knownhosts 文件）。运行时
ssh -T git@github.com
I get Permission denied (publickey).
运行ssh -vT git@github.com 时，我得到：

有些东西很奇怪，但我不太明白问题出在哪里。我使用 GitHub 文档设置了我的密钥，但仍然收到一条权限被拒绝声明。我的密钥是一样的，因为我在 Github 上检查了我的密钥，并确保在运行 ~/.ssh$ ssh-keygen -lf ~/.ssh/id_rsa.pub时数字相同
任何帮助将不胜感激！
【问题讨论】：
-
显然key不匹配，因为
/home/parallels/.ssh/id_rsa被github拒绝了。请在问题中添加ssh -vvvT git@github.com输出。它可能会提供更多指南。 -
@Jakuje 在上面完成
