Enabling SSH access

It is common to have issues with the SSH server that comes preinstalled with Ubuntu:

1. To avoid any problems, remove the OpenSSH package and install it again:

$ sudo apt remove openssh-server$ sudo apt install openssh-server

2. Enable the service so that it starts on boot:

$ sudo systemctl enable ssh$ sudo systemctl start ssh

3. Confirm that the SSH server is up and running:

$ sudo systemctl status ssh

At this stage, you should be able to log in from this host to any other SSH-enabled Ubuntu server, such as your laptop.
