无法启动 OpenBSD 安全 Shell 服务器

我想使用 ssh 来连接 localhost，但这是不可能的。当我写

远程控制[电子邮件保护]-p 22

它显示

ssh：连接到主机 127.0.0.1 端口 22：连接被拒绝

我想检查 ssh 状态但出现以下错误：

状态错误

我认为问题可能与依赖关系有关，所以我把

apt-get 安装 -f

但我也有同样的问题

无法启动 OpenBSD 安全外壳服务器。

怎么了？

sudo /usr/sbin/sshd -ddd

显示这个：

最好的解决方案是删除之前安装的 ssh 服务器/客户端

sudo apt-get remove openssh-server openssh-client --purge && sudo apt-get autoremove && sudo apt-get autoclean && sudo apt-get update

然后安装新的干净纯净的：

sudo apt-get install openssh-server openssh-client
