How To Fix sshd: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu sshd is provided by openssh-server package.

openssh-server is:

This is the portable version of OpenSSH, a free implementation of the Secure Shell protocol as specified by the IETF secsh working group.

Ssh (Secure Shell) is a program for logging into a remote machine and for executing commands on a remote machine. It provides secure encrypted communications between two untrusted hosts over an insecure network. X11 connections and arbitrary TCP/IP ports can also be forwarded over the secure channel. It can be used to provide applications with a secure communication channel.

This package provides the sshd server.

In some countries it may be illegal to use any encryption at all without a special permit.

sshd replaces the insecure rshd program, which is obsolete for most purposes.

To fix this problem, we can install more using the command below.

sudo apt-get -y install openssh-server

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install openssh-server.

sudo apt -y install openssh-server

sudo aptitude install openssh-server
