Debian安裝tree填坑記錄

Debian安裝過程當中遇到一個小問題。 使用命令安裝軟件

#切換到root帳戶
su root
#安裝軟件tree
apt install tree

提示

更換介質 :請把標有 " Debian GNU/Linux 8.6.0 _Jessie_ - Official amd64 DVD Binary-1 20160917-14:25"的盤片插入驅動器"/media/cdrom/"再按回車鍵

解決該問題，須要修改

#修改文件
vi /etc/apt/sources.list
#修改結果如圖
#

# 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
