我正在尝试让我的 Raspberry Pi 无线工作，这样我就可以像使用 Raspbian 一样连接到我的两个独立网络。我在网上学习了一些教程，这是最后一个似乎对我有帮助的教程：https://medium.com/a-swift-misadventure/how-to-setup-your-raspberry-pi-2-3-with-ubuntu-16-04-without-cables-headlessly-9e3eaad32c01
但还是没有网络。

任何帮助都值得感激，我已经厌倦了被电缆绊倒并且无法连接到无线和开发 PLC。

您需要更新您的 netplan 配置。
以下是我的配置/etc/netplan/00-snapd-config.yaml。我最初使用创建了它console-conf，但必须手动编辑它才能使其工作。
ubuntu@ubuntu:~$ sudo cat /etc/netplan/00-snapd-config.yaml
# This is the network config written by 'console_conf'
network:
ethernets:
eth0:
dhcp4: true
match:
macaddress: b8:27:eb:03:91:12
set-name: eth0
version: 2
wifis:
wlan0:
access-points:
my_wifi_ssid: {password: my_wifi_password}
addresses: []
dhcp4: true
nameservers: {}
我首先console-conf使用安装sudo apt install console-conf，然后使用 运行它sudo console-conf。
有趣的是，即使这个工具也无法生成正确的配置。出现以下错误消息：
Network configuration failed: 'Error in network definition
//etc/netplan/00-snapd-config.yaml line 4 column 6: eth0:
set-name: requires match: properties\n'
我手动修改了/etc/netplan/00-snapd-config.yaml- 我从中复制了该ethernets部分50-cloud-init.yaml并在各处使用了一致的缩进。
最后我运行sudo netplan apply。瞧——互联网现在无需以太网电缆就可以工作了！
附言：我怀疑您是否需要经历这个过程console-conf- 只需复制我的配置并使其适应您的用例即可。

我设法通过安装网络管理器并运行 nmtui 将我的 pi3b+ 连接到 ubuntu 服务器 18.04（从 ubuntu-18.04.2-preinstalled-server-arm64+raspi3.img.xz 安装）上的 wifi，nmtui 显示可用 wifi 网络的 ncurses 界面并让您连接和配置它们。
