How to set a static IP using netplan? (running Ubuntu Bionic server)

I've followed/looked at several guides (like this one) on how to do the above.

My problem is that no static IP is getting assigned to the built-in ethernet port. I have run
Code: 
netplan apply
several times. I've also rebooted the PC and still no luck.

I am sure the ethernet port works as I was previously using it on Ubuntu 16.04 just before I decided to fresh install 18.04.2.

Any ideas what I could be doing wrong? I am going to use the ethernet port to connect my main PC to the Ubuntu server via a crossover cable.

If I set the ethernet port to use
Code: 
dchp4:true
and connect an ethernet cable from it to my modem/router and disable my WiFi card (by removing the netplan config), the PC can connect to the net without any issues.

Thanks

Edit: I had a look at /run/systemd/network/config-file-here and it looks correct to me. At the very least representative of the contents of the YAML file. /run/systemd/network folder was mentioned in the netplan website troubleshooting page.
---------------------------

This is the output of
Code: 
netplan --debug apply
which also shows the contents of my YAML files. I have tried with and without dhcp4/dchp6/gateway4/renderer.

Addresses is supposed to be in brackets, show the yaml content not the debug...
 
I think I set mine on the network (L3 switch handling DHCP) side. I'll double check for you when I get home. I've definitely done it before with netplan, and don't remember having issues...
 
I checked. I'm assigning the IP via DHCP server.

I did look over your config. A couple suggestions, and questions.

- Are you sure 192.168.2.1 isn't in your DHCP range and already assigned to another device? I'd suggest trying something else.

- Add version number and renderer to the file:
Code: 
network:
  version: 2
  renderer: networkd

- Remove the line below "addresses:" and add something like:
Code: 
[192.168.2.73/24]
Yes! Do it with brackets to appease us too, please!

- Add at least one nameserver:
Code: 
     nameservers:
       addresses: [8.8.8.8,8.8.4.4]

- Change both the "false" to "no". This may not change the behavior, but is worth trying.
