我在 .bashrc 脚本末尾添加了 ssh 身份，正如服务器在我登录时所说的那样，代理正在使用 pid 8411 运行，并且所有身份都已添加。
从下面的控制台也可以明显看出，我无法使用我的身份。为了使用它们，我需要输入命令来启动 ssh 代理（现在它收到新的 pid 8531），并输入命令将身份添加到代理（再次？），只有这样 git 才会识别身份并允许拉取存储库。
这是怎么回事，我做错了什么？

所以我注意到四个身份中的第一个是可用的。 -v 给出了很多调试行 =)
debug1: Connecting to github.com [140.82.121.3] port 22.

debug1: Local version string SSH-2.0-OpenSSH_8.2p1 Ubuntu-4ubuntu0.7
或者这只是列出了它要查找的身份文件类型？因为再往下我得到了这个：
debug1: Will attempt key: /root/.ssh/id_ed25519 ED25519 SHA256:pHUHZ1LHAiGC0z---------------------- agent

debug1: Will attempt key: /root/.ssh/id_ed25519_sk
debug1: Will attempt key: /root/.ssh/id_xmss
所以看起来它尝试了密钥，但为什么其中第一个密钥上只有一条路径？其他人没有路径，只有我的电子邮件地址？

------------ 更新（aviro 的评论）---------
该代理确实正在以 PID 165201 运行。但是，手动将身份添加到该代理并没有帮助，如下所示。同样如下所示，再次在代理上运行 eval，然后手动添加身份即可解决问题。我注意到只有一个代理正在运行，因此在代理上运行 eval 时，PID 被替换为新的 PID。
