Ubuntu开机log报错，network相关

[univerioiln233]

报错：[FAILED] Failed to listen on Network Service Netlink Socket.
NetworkManager（多数 Linux 发行版默认，如 Ubuntu、Fedora）：
然后我禁用了systemd-networkd
接着开机报错
A start job is running for Wait for Network to be Configured (2min / no limit)
See 'systemctl status systemd-networkd-wait-online.service' for details.

如果默认配置NetworkManager，为什么不禁用systemd-networkd和systemd-networkd-wait-online.service呀？
