我该如何克服这些包依赖问题？

我升级到了 11.10，升级过程中断电了。重启机器后，我尝试继续升级，并在某一时刻进行了部分升级，以解决依赖性问题，我当时认为这些问题与升级失败有关。现在我的系统基本可以正常工作。问题是我无法再安装“acroread”包，因为存在依赖性错误：

我运行的是 64 位系统，但 acroread 似乎需要一些无法安装的 32 位库。在阅读过程中，我发现多架构包发生了一些变化。

有人知道我该如何修复我的系统来解决这个问题吗？

答案1

尝试一下sudo apt-get install -f。它可能会给出一些关于删除和安装软件包的建议，请按照合理方式操作。如果没有帮助，请尝试启动到恢复模式并选择“修复损坏的软件包”。如果这不起作用...我不知道，如果我是你，我会重新安装 Ubuntu。（这是始终将 /home 放在单独分区上的一个很好的理由！）

答案2

最新版本添加了多架构支持。32 位库作为 32 位库添加。我怀疑您需要安装 ia32-libs-multiarch。尝试以下命令：

sudo apt-get install ia32-libs-multiarch:i386
sudo apt-get check

让我大吃一惊。我还发现 aptitude 尚未更新以支持此更改。

答案3

在尝试安装 32 位库之前，您需要启用多架构：

 echo foreign-architecture i386 | sudo tee /etc/dpkg/dpkg.cfg.d/multiarch

完成这些操作后，您就能安装您需要的任何 32 位库。

答案4

只需将命令中的“apt-get”部分替换为“aptitude”，然后按照说明操作，然后就应该没问题了。
