Ubuntu 18.04 安装博通（Broadcom）无线网卡驱动
首先从iso镜像文件中提取出驱动文件。
./pool/main/d/dkms/dkms_2.3-3ubuntu9.2_all.deb
./pool/restricted/b/bcmwl/bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu4_amd64.deb
然后按顺序直接sudo dpkg -i 安装，装完重启即可生效。
sudo dpkg -i dkms_2.2.0.3-2ubuntu11_all.deb
sudo dpkg -i bcmwl-kernel-source_6.30.223.248+bdcom-0ubuntu8_amd64.deb
如果安装过程中报 没有安装gcc 的错误，那么也是直接从镜像文件中提取相关文件dpkg -i 安装即可，缺什么deb包就直接在iso文件中找就行，期间大概安装了10多个deb包，然后才完成gcc和g++的安装。
也可以参考https://www.cnblogs.com/0x4D75/p/9443842.html 配置本地源安装。
在本文的最后部分的history是我的整个安装过程的命令历史记录。
接下来，继续安装dkms和bcmwl

安装完gcc后安装驱动deb包时，爆出这个错误。
