我已经生成了一对 rsa 密钥，并使用它通过 ssh 进入我的服务器，无需密码。服务器包含文件~/.ssh/authorized_keys，我将客户端的文件复制到该文件中~/.ssh/id_rsa.pub，如下所示：
ssh-rsa AAAAB3NzaC1yc2wqegqeweqrwqgwqet......iCA2unoYGtLgS7F8veyKl85jJwdZpwqhCXnkei4gq+ABZm7STs/7ns= [email protected]
但是，按如下方式 ssh 后，我得到了以下信息：
my-shell ~ % ssh -Yvv prikshet@proto1
OpenSSH_8.1p1, LibreSSL 2.7.3

服务器仍在要求输入密码。服务器~/.ssh/authorized_keys权限如下：
my_shell~$ sudo ls -lah ~/.ssh/authorized_keys
[sudo] password for prikshet:
-rw------- 1 root root 595 Sep 11 18:03 /home/prikshet/.ssh/authorized_keys
为什么服务器仍要求输入密码？
