lubuntu 16.04 非联网状态下安装失败

today i use lubuntu 16.04 to install with my old pc. but at the stage of install boot program failed. I tried with the disk position and install from the terminal or insall from lubuntu desktop program, all failed.

At last , i watched the ouput from the install program., that it seemes it can’t apt-get install grub-pc with the install, so absolutely, I gave it a network line, all fixed.

简单点：

lubuntu16.04在pc上安装，必须得联网。
