安装 tzdata-java 包时出现问题（未满足的依赖项）

我家里有一台 Debian 6.0，由 Lenny 升级。我需要安装该tzdata-java软件包，但当我安装时，apt-get install我收到以下消息：

以下软件包具有未满足的依赖关系：

tzdata-java：依赖：tzdata（= 2011c-0squeeze1）但需要安装 2011d-0lenny1

E: 包装破损

我在网上搜索过，但我不明白这个错误意味着什么。

答案1

我在 squeeze 上也遇到过同样的问题，但这个答案也适用于旧版本。只需根据tzdata需要更改 的版本号即可。

首先，执行以下操作apt-cache showpkg tzdata：

raphael@hydra:~$ apt-cache showpkg tzdata-java
Package: tzdata-java
Versions: 
   (snip)

Dependencies: 
2011k-0squeeze1 - tzdata (5 2011k-0squeeze1) 
Provides: 
2011k-0squeeze1 - 
Reverse Provides:

如您所见，这取决于tzdata (2011k-0squeeze1)- 至少取决于我的系统。现在让我们看一下tzdata：

raphael@hydra:~$ apt-cache showpkg tzdata
Package: tzdata
Versions: 
   (snip)

Provides: 
2011l-0squeeze1 - tzdata-squeeze 
2011k-0squeeze1 - tzdata-squeeze 
Reverse Provides:

哦，看，我已经安装了2011k新旧版本2011l。我不知道为什么它不起作用，但是，我们可以强制 apt-get 降级tzdata，正如我们将看到的，这将在时空中造成撕裂：

raphael@hydra:~$ sudo apt-get install tzdata=2011k-0squeeze1

现在你可能会想，嘿，如果我运行更新管理器，它会安装较新的 tzdata！但不，它不会：

raphael@hydra:~$ sudo apt-get upgrade

（薛定谔的包裹反击了。）

瞧，现在我可以安装tzdata-java：

raphael@hydra:~$ sudo apt-get install tzdata-java
Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following NEW packages will be installed:
  tzdata-java
