升级到squeeze/testing期间的Perl冲突

Question

为了在我的服务器系统上获得python2.7 (运行Debian squeeze)，我在升级所有包时遇到了一些问题。我完全不知道从这里该做什么：

# apt-get upgrade -f

在我的sources.list中，我有：

deb-src http://ftp.dk.debian.org/debian/ squeeze main

deb http://security.debian.org/ squeeze/updates main

对如何进行有什么建议吗？

Answer 1

系统需要您的帮助才能继续，请使用aptitude而不是apt-get。

aptitude full-upgrade

你会得到相同的信息和一个可能的解决方案，这将涉及到更新一些包和删除其他包。如果情况可以接受，则继续。否则，假设aptitude建议删除gnome，这对您来说是不可接受的。在gnome旁边的要升级、删除等包的列表中，您将看到一个数字，例如23 gnome。键入R23放弃涉及删除gnome的所有解决方案。点击Intro，然后点击n，以不接受解决方案。

Aptitude将为您提供另一个诱人的解决方案，它不会建议删除gnome (如果可用)。冲洗并重复操作，直到出现可接受的解决方案。

这只是一个开始，记住，man aptitude是你最好的朋友。
