找不到应该可用的包。

Question

当我运行apt-get install weboob时，我会“无法找到包weboob”

但是，可以为debian：https://packages.debian.org/jessie/weboob提供的包si

我以前运行过apt-get update

smith@debianvm:~$ sudo apt-get update
[sudo] password for smith: 
Get:1 http://security.debian.org jessie/updates InRelease [63.1 kB]

Get:7 http://security.debian.org jessie/updates/main Translation-en [163 kB]

这是debian的8.6版。从现在起我不知道该怎么办了。

Answer 1

您的sources.list文件是不完整的；对于Debian 8，您应该使用以下内容

deb http://httpredir.debian.org/debian jessie main
deb http://security.debian.org/ jessie/updates main

至少(这将为您提供Debian 8中的所有包及其安全性更新)。

如果您希望能够下载源代码包，还应该添加

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

如果您还希望在“正式”发布为点更新之前接收稳定的更新，则可以添加

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

最后，如果您想要访问靠背，可以添加

deb http://httpredir.debian.org/debian jessie-backports main
deb-sec http://httpredir.debian.org/debian jessie-backports main
