一些提供商会提供公共 APT 存储库的基本 URL,并且禁止在 HTTP 文件服务器中列出目录。有没有办法了解他们提供哪些套件/组件/架构?
就像先获取 的内容dists/*
,然后获取 的内容dists/<suite>/*
,然后获取 的内容dists/<suite>/<component>/*
。
对于链接http://http.us.debian.org/debian/
我想查看列表:
stable stretch testing sid
然后对于给定的套件我想要查看列表:
main contrib non-free
进而:
amd64 mips
一切都在这样的路径中:
http://http.us.debian.org/debian/dists/stretch/main/binary-arm64/
具有封闭目录列表的 repo 示例为:https://apt.releases.hashicorp.com
答案1
如果你了解该套件,并且仓库足够现代,则组件和体系结构将在InRelease
文件中,例如,http://http.us.debian.org/debian/dists/bullseye-backports/InRelease(或Release
旧存储库的未签名文件):
% curl -sL http://http.us.debian.org/debian/dists/bullseye-backports/InRelease | head -n 20

但至少需要知道套件。我不知道如何仅从 repo 基础 URL 发现它。

对选定的 APT 数据库提供有限的支持,实现 madison CGI 接口:
sudo apt install devscripts
rmadison emacs
rmadison -u debian emacs
rmadison -u ubuntu emacs
在 Debian WEB 上,可以通过单个查询来查询所有注册源:
https://qa.debian.org/madison.php?package=emacs&table=all&a=&c=&s=#
输出如下所示:
emacs | 45.0ubuntu1 | trusty | all
emacs | 46.1 | xenial | all
emacs | 47.0 | bionic | all
emacs | 1:26.3+1-1ubuntu2 | focal/universe | source, all
emacs | 1:27.1+1-3ubuntu5 | jammy/universe | source, all
emacs | 1:27.1+1-3ubuntu5 | kinetic/universe | source, all
emacs | 1:27.1+1-3ubuntu5 | lunar/universe | source, all
