我尝试像这样在Ubuntu 16.04上安装OpenSSH服务器：
sudo apt-get install openssh-server
但是，它显示以下消息：
dell@dell-Latitude-E6400:~$ sudo apt-get install openssh-server Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: openssh-server : Depends: openssh-client (= 1:7.2p2-4) but 1:7.2p2-4ubuntu2.8 is to be installed Depends: openssh-sftp-server but it is not going to be installed Recommends: ncurses-term but it is not going to be installed Recommends: ssh-import-id but it is not going to be installed E: Unable to correct problems, you have held broken packages.
尝试使用这个对我有用。
sudo apt purge openssh-client
实际上您的系统上已安装openssh-client，您必须先删除它，然后使用此命令安装openssh-server。
sudo apt install openssh-server
