sudo apt install openssh-server -y

• sudo apt update

  Updates the package list from Ubuntu repositories to get info on the latest available versions.

• sudo apt install openssh-server -y

  Installs the OpenSSH server package; -y automatically answers “yes” to prompts.

Step 2: Check SSH Service Status

sudo systemctl status ssh

• Shows whether the SSH server service is active (running), inactive, or failed.

Step 3: Start SSH Service (If Not Running)

sudo systemctl start ssh

• Starts the SSH server service immediately.

Step 4: Enable SSH to Start Automatically on Boot

sudo systemctl enable ssh

• Configures the system to start the SSH server automatically every time the server boots up.
