答案1
对于 openssh-server 的问题，我通过以下方式解决：（
sudo apt-get install openssh-client=1:7.6p1-4复制消息中提到的版本以手动安装所需的依赖版本）
答案2
运行这些命令后它起作用了：
sudo apt-get install openssh-client=1:8.2p1-4
和
sudo apt-get install openssh-server
答案3
尝试运行“apt-get install -f”。如果不起作用，请运行“apt update”、“apt-get update”，然后再次运行“apt-get install -f”。为了将来监控损坏的软件包，请通过运行“apt install synaptic”来安装 Synaptic。当 Synaptic 启动时，它会在窗口底部通知您损坏的软件包。
答案4
openssh-client 将作为依赖项自动安装。因此请先清除它，然后执行 openssh-server 安装。
sudo apt purge openssh-客户端
和
sudo apt-get 安装 openssh-server
