当我尝试运行 apt-get 或安装 Ubuntu 升级时，无法启动 OpenBSD Secure Shell 服务器错误

我在 Ubuntu 16.04 LTS 上。

我运行了 ssh 服务器并且它正常工作了好几个月，直到有一次导致它失败。

现在，我无法从 Canonical 进行常规的 Ubuntu 更新。我无法运行apt-get更新。例如

$ sudo apt-get upgrade python3

当我检查 ssh 服务器的状态时，

sudo service ssh status

谢谢你的帮助。

我不知道这是否有帮助，但我有 /etc/init.d以下 2 个脚本......

ssh.sh

这似乎是 Ubuntu 提供的 shell 脚本

和

ssh-start.sh

其中包含

除此之外，我还有/etc/systemd/system/sshd.service，这是一个链接/lib/systemd/system/ssh.service

其中包含：

还是有问题。他们现在导致诸如 apt install 之类的事情失败。

谢谢，安德鲁邓恩，但我研究了那个答案和解决方案对我不起作用。

这是输出 journalctl -xe
