为什么apt-get无法找到拼图文件或拼图？

Question

debian系统有些地方我做得不对，我非常确信jigdo程序包含在Debian存储库系统(https://packages.debian.org/search?keywords=jigdo&searchon=names&suite=jessie§ion=all)中，但是当我尝试apt-get install jigdo-file时，它说是unable to locate jigdo-file package。

我的source.list是：

# deb cdrom:[Debian GNU/Linux 8.3.0 _Jessie_ - Official amd64 xfce-CD Binary-1 20160123-19:00]/ jessie main

# deb cdrom:[Debian GNU/Linux 8.3.0 _Jessie_ - Official amd64 xfce-CD Binary-1 20160123-19:00]/ jessie main

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

# jessie-updates, previously known as 'volatile'
# A network mirror was not selected during install.  The following entries
# are provided as examples, but you should amend them as appropriate
# for your mirror of choice.

# deb http://ftp.debian.org/debian/ jessie-updates main
# deb-src http://ftp.debian.org/debian/ jessie-updates 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apt-get update清理任何东西，它仍然找不到它。我错过了什么？谢谢

Answer 1

您的sources.list似乎有杰西更新(以前称为“易失性”)和杰西安全，但你错过了正常杰西的来源。

增加：

deb http://httpredir.debian.org/debian/ jessie main contrib non-free

做apt-get update应该能解决这个问题。
