How can I install openssh-server without openssh-client on Ubuntu Server 20.04

I'm trying to install openssh-server on a Ubuntu server 20.04. When I try to install it with the following command:

sudo apt-get install openssh-server

the process wants to install openssh-client, openssh-sftp-server and ssh-import-id. If I proceed and try to remove openssh-client, openssh-server and the other packages are removed too.

Is there a way to install openssh-server only?

openssh-server has a dependency on openssh-client. That means the client is needed by the server. You will need to install the client. I would like to show you the full list of dependencies, but I do not have 20.04 installed, yet. Try this command:

less /var/lib/apt/lists/security.ubuntu.com_ubuntu_dists_focal-security_main_binary-amd64_Packages

Then type in /Package: openssh-server to find the section for openssh-server. Then look for the Depends: line just below that. It should show you what packages it depends on.
