今天在虚拟机配置ssh的时候,遇到ubuntu安装openssh-server 报依赖错误的问题,报错信息如下:

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 (= 1:7.1p1-4) Depends: openssh-sftp-server 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.

解决

要安装对应版本的openssh-clien,来替换ubuntu自带的ssh
然后再输入:

sudo apt-get install openssh-client=1:7.1p1-4 Reading package lists... Done Building dependency tree Reading state information... Done The following packages were automatically installed and are no longer required: libsnapd-glib1 snapd-login-service Use 'sudo apt autoremove' to remove them. Suggested packages: ssh-askpass libpam-ssh keychain monkeysphere The following packages will be DOWNGRADED: openssh-client 0 upgraded, 0 newly installed, 1 downgraded, 0 to remove and 1 not upgraded.

再用
sudo apt-get install openssh-server
通过以下命令启动ssh服务
sudo service ssh start
sudo /etc/init.d/ssh start
如果没有出错就可以用ssh的软件,输入虚拟机的 IP 地址进行链接。
