I am running into some issues configuring netplan on Ubuntu 18.04 server to bond my four hardware ethernet ports named eno1, eno2, eno3, eno4 using the 802.3ad protocol. I've consulted the netplan man page and put together the following config file /etc/netplan/50-cloud-init.yaml:
network:
version: 2
renderer: networkd
ethernets:
eports:
match:
name: eno*
bonds:
bond0:
interfaces: [eports]
addresses: [192.168.1.101/24]
gateway4: 192.168.1.1
nameservers:
addresses: [8.8.8.8, 8.8.4.4]
parameters:
mode: 802.3ad
lacp-rate: fast
mii-monitor-interval: 100
Upon running the command sudo netplan --debug apply I receive the following information:
** (generate:6473): DEBUG: 00:39:14.911: Processing input file //etc/netplan/50-cloud-init.yaml..

I'm not sure what to make of the statement
Cannot replug bond0: cannot read link /sys/class/net/bond0/device: [Errno 2] No such file or directory: '/sys/class/net/bond0/device'
since the directory /sys/class/net/bond0 was generated by the netplan apply command.
I checked my ifconfig output and my network devices seem to be configured correctly with the exception that no address is set for bond0:

The ether XX:XX:XX:XX:XX:XX statements are in place of each interfaces's mac address. In the original output, all addresses are the same.
What am I missing to successfully configure my system?
