我的 debian 是从 USB 盘安装的——/dev/sdb。
从 CD 安装 pppoe 软件包很简单。
sudo vi /etc/apt/sources.list
deb cdrom:[Official Debian GNU/Linux Live 9.2.0 lxde 2017-10-07T13:15]/ stretch main
sudo apt-get install pppoe
没有CDROM，我的电脑上有USB。
我想从 U 盘安装 pppoe 软件包。
sudo mount /dev/sdb /home/back
ls /home/back/
boot d-i dists isolinux live pool
将 USB 磁盘指定为源。
sduo vi /etc/apt/sources.list
deb file:/home/back/ stretch main contirb
用U盘安装。
sudo apt-get install pppoe

该软件包pppoe不包含在Debian Live 9.2.0 lxde.iso，您可以从这里查看包列表：debian-live-9.2.0-amd64-lxde.packages
您可以使用命令行检查pppoe包：
curl https://cdimage.debian.org/debian-cd/current-live/amd64/iso-hybrid/debian-live-9.2.0-amd64-lxde.packages | grep pppoe
