Ubuntu 23.04启动时出现「Wait for Network to be Configured」问题的排查求助

Hey everyone, this seems to be a recurring issue—I’ve even posted about it before myself! But now it’s popping up again, and I can’t pin down exactly where the problem lies.

My /etc/netplan/*.yaml configuration looks like this (which I thought would typically resolve this kind of issue, though I just spotted a typo in verson instead of version—I’ve corrected that but still see the same problem):

network:
  version: 2
  renderer: networkd
  ethernets:
    enp3s0:
      dhcp4: true
      optional: true
    enp4s0:
      dhcp4: false
      optional: true
    fake0:
      dhcp4: false
      optional: true

When I run networkctl, it shows that enp3s0 (the interface I use for internet access) is properly configured. fake0 is also listed as configured, but enp4s0 is stuck in the "configuring" state.

I’m running Ubuntu 23.04.

Does anyone have any tips on where I should look next to troubleshoot this?
