我对 debian 软件包系统有些不太满意，我非常有信心 jigdo 程序包含在 Debian 存储库系统中（https://packages.debian.org/search?keywords=jigdo&searchon=names&suite=jessie§ion=all）但是当我尝试时apt-get install jigdo-file它说unable to locate jigdo-file package。
我的来源列表是：
# deb cdrom:[Debian GNU/Linux 8.3.0 _Jessie_ - Official amd64 xfce-CD Binary-1 20160123-19:00]/ jessie main

deb http://httpredir.debian.org/debian/ jessie-updates main contrib non-free
deb-src http://httpredir.debian.org/debian/ jessie-updates main
我做了apt-get update任何清理，但仍然找不到它。我缺少什么？谢谢

您的sources.list似乎有jessie-updates（以前称为“易失性”）和jessie安全性，但您缺少正常的jessie源。
添加：
deb http://httpredir.debian.org/debian/ jessie main contrib non-free
并采取行动apt-get update应该解决它。
