我是 Unbuntu Server 22.04.2 的新手，启动时间很长。
我使用一台小型无风扇 I3 PC，配有 2 个以太网和 WIFI。我只使用一个以太网。
我的第一次调查是为了提取以下信息：
在启动时我有提取：
sudo journalctl -b
Nov 01 12:35:40 hsm3 systemd-timesyncd[630]: Network configuration changed, trying to establish connection.
Nov 01 12:35:41 hsm3 systemd-networkd-wait-online[668]: Timeout occurred while waiting for network connectivity.
Nov 01 12:35:41 hsm3 systemd[1]: systemd-networkd-wait-online.service: Main process exited, code=exited, status=1/FAILURE
我尝试通过添加可选：true 来更改网络计划，但没有成功：
sudo nano /etc/netplan/00-installer-config.yaml
# This is the network config written by 'subiquity'
network:
ethernets:
enp2s0:
dhcp4: true
optional: true
enp3s0:
dhcp4: true
optional: true
version: 2
最后我找到了一个让我不满意的扭转局面的解决方案。添加超时！该命令仍然会产生问题，但我不会等待超过 5 秒 --timeout=5：
sudo systemctl edit --full systemd-networkd-wait-online.service

但我不喜欢这种“非解决方案”。
你能帮我解决根本问题吗？
向所有人致敬
使用版本 22.04.03 LTS 更新后结果相同：

我还有第二台电脑，我在上面安装了版本 23.10，结果相同。
还有其他想法吗？
