简而言之，您已经加密了主文件夹(即使使用AuthorizedKeysFile也已加密)，因此服务器无法对您进行身份验证.一种可能是将授权密钥移到其他位置(AuthorizedKeysFile /etc/ssh/%u/authorized_keys)，并在登录时解密主文件夹，或者仅删除加密. 官方文档对其进行了很好的描述.

In short, you have encrypted home folder (even with your AuthorizedKeysFile) and therefore the server can't authenticate you. One possibility is to move the authorized keys somewhere else (AuthorizedKeysFile /etc/ssh/%u/authorized_keys) and decrypt your home folder upon login or just remove the encryption. Official documentation describes it well.
