Solution to dependency error reported by openssh-server Installation in ubuntu,
System Environment

Linux user #50~14.04.1-Ubuntu SMP Wed Jul 13 01:06:37 UTC 2016 i686 i686 i686 GNU/Linux
Error reported

Run the following command to install openssh-server:

sudo apt-get install openssh-server

The installation was not successful and I received the following prompt:

The following software packages have dependency: openssh-server: Dependency: openssh-client (=. 6p1-2ubuntu1). 6p1-2ubuntu2.7 is about to be installed. Recommended: ncurses-term, but it will not be installed. Recommended: ssh-import-id, but it will not be installed. E: the error cannot be corrected, because you require some software packages to maintain the status quo, that is, they break the dependency between software packages.

This is because openssh-server depends on openssh-clien. Isn't ubuntu built-in openssh-client? The reason is that the built-in openssh-clien is different from the version on which the openssh-server to be installed. The version on which the client depends is. 6p1-2ubuntu1.

Therefore, we need to install the corresponding version of openssh-clien to overwrite the openssh-clien that comes with ubuntu:

$ Sudo apt-get install openssh-client = 1:6. 6p1-2ubuntu1 is reading the package list... the dependency tree of the software package being analyzed is reading status information... the following software packages recommended for installation: libpam-ssh keychain monkeysphere will be [downgraded]: openssh-client has upgraded 0 software packages, and 0 new software packages are installed, 1 software package is downgraded, 0 software packages are to be detached, and 0 software packages are not upgraded.

After the installation is complete, install openssh-server again and you will be able to install it successfully:

Run the ps command to find the ssh system process. If sshd is found, the installation is successful:

$ ps -e | grep ssh4723 ?        00:00:00 sshd
