实践记录：

1、将debian的iso镜像复制到制定目录，比如： /home/debian/1.iso

mkdir /home/debian
cp /mnt/usb/xxx.iso /home/debian/1.iso

2、讲/home/debian/1.iso镜像挂载到文件系统，比如/mnt/debian/1

mkdir -p /mnt/debian/1
mount /home/debian/1.iso /mnt/debian/1

3、编辑/etc/apt/sources.list文件（注意备份原文件）

mv /etc/apt/sources.list /etc/apt/sources.list.bak
vi /etc/apt/sources.list
# 添加
deb [trusted=yes] file:///mnt/debian/1   bullseye contrib main
