I'll paste the sequence of commands I'm trying to run to configure desktop Ubuntu 18.04 NetworkManager according to the answer in this SO question. When I perform the steps in the answer I end up with an "Error: connection verification failed".
nmcli connection show --active
NAME UUID TYPE DEVICE LINKSYS99999 ... wifi wlp4s0
nmcli connection edit

nmcli> verify fix
Verify connection: 802-11-wireless.ssid: property is missing The error cannot be fixed automatically.
What is going on and how do I fix it? Do I need to post all my wireless details according to this SO guide?
