I have a server installed with Ubuntu 22.04, with two physical network interfaces - eno1 and eno2, and I configure these network interfaces with netplan (which uses systemd-networkd). eno1 is with link detected, and it is configured with dhcp, and eno2 is without link detected (which is OK), and it is configured with a local IP.
The problem: eno2 do not get a local IP address via netplan.
The files:
cat /etc/netplan/50-eno1.yaml
network:
version: 2
renderer: networkd
ethernets:
eno1:
dhcp4: true
dhcp6: false

NOTE: When I run ip addr add 192.168.0.10/24 dev eno2 it works and I have an IP (pingable) on eno2. But I wish to have it with netplan.
