systemd-networkd-wait-online启动失败并超时。我运行的是 Ubuntu 22.04.3
我有三个接口：

以下是系统启动后各种测试的结果
# "Timeout occurred while waiting for network connectivity."
/lib/systemd/systemd-networkd-wait-online --any
/lib/systemd/systemd-networkd-wait-online --interface=lo
/lib/systemd/systemd-networkd-wait-online --ignore=lo
# Works
/lib/systemd/systemd-networkd-wait-online --interface=enp27s0
/lib/systemd/systemd-networkd-wait-online --interface=enp33s0
/lib/systemd/systemd-networkd-wait-online --interface=enp33s0 --interface=enp27s0
这是预期的吗？我还可以做些什么来解决这个问题吗？
