Netplan 没有自动连接到网络

network-config我使用描述我的 Wi-Fi 网络的文件为 Raspberry Pi 4 安装了 Ubuntu 18.04.4 。此文件已自动复制到/etc/netplan/50-cloud-init.yaml。

但是，RPi 没有自动连接到网络。

当我运行时sudo netplan --debug apply它确实连接了（记录如下）。

但我想了解为什么它首先不能自动工作，所以我不需要控制台访问来启动每个设备的网络连接。

我确实看到了这一点/var/log/cloud-init-output.log：

network_state.py[WARNING]: Wifi configuration is only available to distros withnetplan rendering support.

这条消息似乎来自cloud-init 的这一部分。

你可能受到https://bugs.launchpad.net/cloud-init/+bug/1892851。我们预计此错误将很快在 Ubuntu 20.10 中得到修复，并且修复将很快移植到 Ubuntu 20.04 LTS。我们目前尚未承诺将此修复移植到 Ubuntu 18.04 LTS；获取修复的最快方法是使用 Ubuntu 20.04 LTS 而不是 18.04 LTS。
