Creating bonded interface with new Ubuntu Server 18.04 install does not work

Final Update I started fresh again with DHCP on the client LAN. It successfully installed and was able to resolve the address to grab updates. Since a bond was not created initially, I installed ifenslave, and configured the bond manually using the server LAN at the gateway. I applied the configuration with netplan apply, and everything started working. ip route shows the routing table with the correct gateway, and I can update, install, ping, etc. I do not know why this is failing on a fresh installation, and I'm not sure if this would work for an "answer," since I don't understand why it's failing in the first place. Perhaps this is a lack of knowledge issue and not an Ubuntu issue?

Update 2 I cannot set up a bond at all, whether it be static or dhcp. I have to use DHCP on a single interface just to get the OS installed.

Update Setting up a static IP with a bonded interface does not work, but installing with DHCP does work. I've successfully installed the OS with a static IP and a bonded interface on many other servers, but this one is not working. I will see if I can manually set it up after everything installs and return with another update.

Brand new server out of the box. Brand new Ubuntu 18.04 installation. Once I get to the network config screen, I create an active-backup bond.

Subnet: 192.168.64.0/18
Address: 192.168.64.92
Mode: active-backup
Nameservers: 192.168.70.80,192.168.3.222

Once the installation was complete, I realized I had no network. Couldn't ping internally or externally. I tried again, and looked at the full log. I saw this:

Err:5 http://archive.ubuntu.com/ubuntu bionic InRelease

Temporary failure resolving 'archive.ubuntu.com'

I have done this on many servers, and now this has happened on two new servers in a row. Every search I do, I only get results for apt update. This is a fresh install. Any ideas? I can't install packages, update, ping, nothing. And I can't find any resources because every example is for updating. First server I passed it off as a fluke, but now it's the 2nd server in a row.

There is no IP conflict, and I know with 100% certainty that my setup config is correct.

Silly question, but have you confirmed the network device is operational?

As far as I can tell, yes. The interfaces show up in the BIOS. This is a brand new Dell R440 with NON-RAID drive.

I started over with the installation and went with DHCP. It is downloading archives as I type this. I don't understand why it doesn't work upon initial setup, but I will try to manually create the bonded interface, static IP, etc and return with updates.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
