github - Hetzner 错误：权限被拒绝（公钥）

Question

我正在尝试通过 hetzner deploy 上的 rails gemfile 从 github 获取 repo！但是在 ssh 中显示了这个结果！

ssh -vT [e-mail]

我已经尝试了一切，因为在 /etc/ssh/sshd_config 上更改 PasswordAuthentication yes

在 known_hosts 和 authorized_keys 添加了 keygen 在 server 和 github 上添加了 keygen

创建一个ed25519 keygen并尝试过

一切仍然

github 给我 [e-mail]：权限被拒绝

.ssh/config 文件

Host github.com
User git

PreferredAuthentications publickey

IdentityFile /home/dc~/.ssh/id_rsa.pub

在hetzner 专用服务器上，您首先需要检查的是：

ssh -Tv [e-mail]

只要您没有看到“欢迎”消息，任何其他进程（假设它是使用该服务器上的相同用户帐户执行的）将无法使用 SSH 从 GitHub 获取。
