当本地帐户时，我可以使用 (id_rsa) 密钥连接到我的服务器在服务器上已登录。
如果我重新启动服务器并将其保留在登录管理器中，然后尝试连接，SSH 将返回
Permission denied (publickey)
服务器和客户端上 /.ssh 和 .ssh/authorized 密钥的权限分别为 700 和 600。
客户：
henry@MSI-LT17:~ > ls -la ~ | grep ".ssh"
drwx------ 3 henry henry 4096 Jan 23 16:31 .ssh
henry@MSI-LT17:~ > ls -la ~/.ssh | grep "authorized_keys"
-rw------- 1 henry henry 228 Jan 23 16:31 authorized_keys
服务器：
henry@henry-dt:~ > ls -la ~ | grep ".ssh" drwx------ 2 henry henry 4096 Jan 19 18:24 .ssh
henry@henry-dt:~ > ls -la ~/.ssh | grep "authorized_keys"
-rw------- 1 henry henry 397 Jan 19 18:56 authorized_keys
以下是尝试登录的 -vvv 输出：

我怀疑跟这debug1: key_parse_private2: missing begin marker件事有关系……
