I have a computer with an industrial control type motherboard with no video output ports or video cards.
Ubuntu 18.04 server OS boots from a Compact-Flash drive. I installed the OS via cloning.
I would like to add an ssh server to the OS, by adding it to the disk.
The ssh-server was not installed at the time of server OS installation.
How do I add an ssh-server to a bootable hard drive?
