I have two home computers. One is running 16.04 and the other had 14.04 installed. The 14.04 machine has since been upgraded to 18.04.
When it was 14.04 and 16.04, connecting the two computers directly with an Ethernet cable was a straightforward matter. I'd set static IPs via an dialog like the one below and I'd be ready.
It's not as straightforward with 18.04, apparently. Before my attempt to pair the two computers with the cable, I was using a
Wired connection 1 to connect to the Internet on the 18.04 machine -- I'd just plug it in and I'd be online in seconds. After the pairing attempt, not only were the two machines not seeing each other on the private network as I was expecting, but
Wired connection 1 is no longer connecting to the Internet when I switch to it.
Here is the dialog I'm struggling with on 18.04. As can be seen, it's different from the first image which is the dialog on both 14.04 and 16.04.
So how do I do it?
My intention is to connect the two computers together to arrange a fast transfer of files between them. Attempting to connect to the local network on the 18.04 machine throws an error
Activation of network connection failed.
