Yes, you might be correct here!
It was a couple of years ago so I don't remember exactly. It could have been a
monitor and keyboard directly connected in this case.
If so my discovery only applies to that case, but I recommend killing the
screensaver on the console anyway, why do we really need such a function?

What I do know is that when I dist-upgraded the other Ubuntu 16.4 server I did
so using ssh (PuTTY) but only when I had travelled to the office in Texas so I
could go to the hardware if things screwed up. This server also manages the
OpenVPN connection into the office LAN over there so I would not be able to fix
any errors popping up...

The ssh from inside the local office worked fine at that time, though.

Now I face the next upgrade to Ubuntu 20.4 and this time I cannot travel to the
office due to the Covid-19 restrictions..
