bcmwl-kernel-source  软件包 post-installation脚本子进程返回错误状态10(313)

执行下面脚本，出现的结果是一样的
sudo apt-get install bcmwl-kernel-source

sudo apt purge bcmwl-kernel-source
sudo apt-get install broadcom-sta-source
sudo apt-get install broadcom-sta-dkms
sudo apt-get install broadcom-sta-common
# 要重启，另外在重启前执行了sudo apt-get install bcmwl-kernel-source  但是还报错了。反正最后无线网卡可以用了

adding your user to the "docker" group with something like:

  sudo usermod -aG docker fan

Remember that you will have to log out and back in for this to take effect!
