Debian安装tree填坑记录

Debian安装过程当中遇到一个小问题。 使用命令安装软件

#切换到root帐户
su root
#安装软件tree
apt install tree

提示

更换介质 :请把标有 " Debian GNU/Linux 8.6.0 _Jessie_ - Official amd64 DVD Binary-1 20160917-14:25"的盘片插入驱动器"/media/cdrom/"再按回车键

解决该问题，须要修改

#修改文件
vi /etc/apt/sources.list
#修改结果如图
#

# deb cdrom:[Debian GNU/Linux 8.6.0 _Jessie_ - Official amd64 DVD Binary-1 20160917-14:25]/ jessie contrib main

#deb cdrom:[Debian GNU/Linux 8.6.0 _Jessie_ - Official amd64 DVD Binary-1 20160917-14:25]/ jessie contrib main

deb http://security.debian.org/ jessie/updates main contrib
deb-src http://security.debian.org/ jessie/updates main contrib
