我正在尝试安装最新版本的subversionon Sid，但由于它有错误，我收到警告并中止安装。如何找到以前的版本、安装它并固定直到错误得到解决？

答案1
您可以指示apt-get安装特定版本的软件包。对于你的例子：
apt-get install subversion
您可以将版本附加到包名称中，例如
apt-get install subversion=1.9.2-1
到寻找软件包版本，Debian wiki 页面回滚更新显示了一个可以在其中找到该信息的示例
http://www.debian.org/distrib/packages， IE，
https://www.debian.org/distrib/packages#search_packages
或（旧版本）通过
http://snapshot.debian.org/
http://snapshot.debian.org/package/subversion/
节目
http://snapshot.debian.org/package/subversion/1.9.2-2/
http://snapshot.debian.org/package/subversion/1.9.2-1/
http://snapshot.debian.org/package/subversion/1.9.1-1/
等等。
/etc/apt/preferences最后，Debian 页面显示了（作为示例）要进行的更改别针包裹。

这才是问题的最终解决方案。重要的是，sources.list 中存储库的 URL 应该是包含所需包的存储库的完整 URL，在本例中http://snapshot.debian.org/archive/debian/20150924T154447Z/。有一篇很好的文章写在http://mindref.blogspot.co.uk/2012/02/apt-revert-upgrade.html并在相关问题中也进行了解释 -将 Debian 包固定到存储库和版本的正确语法是什么？
