I am revamping my home server and bumped myself early up to Jammy Jellyfish...
however to my peril I reused my netplan config and after hitting my server with
the 'ol netplan apply
I lost connection...
DNS still seemed to kinda work externally, but internally nothing was up...
Turns out Netplan got a little change in how to express the gateway
key in the netplan config!
