我在生产环境中有一堆旧机器，都运行着 uBuntu 9.10。我现在想将其升级到 10.04 发行版，但我收到以下错误（我猜是因为存储库已过期）
The following packages have unmet dependencies:
update-manager-core: Depends: python-apt (>= 0.7.5) but it is not going to be installed
E: Broken packages
我的所有 apt-get update / apt-get upgrade 命令均失败并出现错误

E: Some index files failed to download, they have been ignored, or old ones used instead.
有人能帮我完成下一步并帮助我解决这个问题吗？如果有任何 PPA 或任何其他维护 update-manager-core 及其所有依赖项的存储库，那么我很乐意使用它。
感谢 Sparsh Gupta

以防万一LucidUpgrades不再起作用，直接从 Jaunty 转到 Lucid 并跳过 Karmic。首先备份有价值的数据，
以 root 身份运行：
cd /etc/apt
perl -i.bak -pe 's/jaunty/lucid/' sources.list
aptitude update
aptitude dist-upgrade
