没有说任何关于权限的事情。SSH 适用于其他主机 - 我可以由此得出结论，这是服务器上的公钥问题，而不是我的 PC 上的问题？
我唯一能想到的另一件事是我的 PC 上的用户名是“me”，而远程服务器上的用户名是“ae”。
当它工作时，对于另一台服务器，它看起来像这样：
...
debug1: Next authentication method: publickey
debug1: Offering RSA public key: /home/me/.ssh/id_rsa
debug1: Server accepts key: pkalg ssh-rsa blen 279
debug1: Authentication succeeded (publickey).
