Debian系列Linux共用相同的deb安装包，拥有大量的各种软件，是Linux里面最主要的生态系。包括Ubuntu及其衍生版本如Lubuntu/Mate/Kubuntu等，在ARM上也有恒好的支持如Rapsberry、LXDE、Hypriot等。
对于Linux服务器的版本如Hypriot，初始镜像没有连接无线网络，怎么安装上网络支持呢？
需要首先连接有线网，或者下载network-manager相应版本，然后运行dpkg -i 安装上，然后就可以使用nmcli的命令行进行网络管理了。
sudo apt install network-manager
安装完后，可以使用下面的nmcli命令行或者nmtui进入交互界面进行管理。
