错误尝试安装 TeamViewer 后，包管理中断（我从 TeamViewer 网站选择了错误的 TeamViewer 包）。
我努力了：
sudo apt-get clean
sudo apt-get update
那么如果我这样做：
sudo apt-get install -f
我得到：

删除问题包似乎不起作用：

You might want to run 'apt-get -f install' to correct these:

ia32-libs-multiarch:i386 : Depends: libsane:i386 but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
删除 ia32-libs-multiarch:i386 也不起作用：
sudo apt-get remove ia32-libs-multiarch:i386

Ubuntu 软件中心现在无法使用，因为它不断给我一个错误对话框说“在修复软件包目录之前，无法安装或删除项目。您想现在修复它吗？” - 但是修复失败，如下所示：

我还收到一条通知，提示“发生错误，请从右键菜单运行包管理器或在终端中运行 apt-get 查看错误所在。错误消息为：‘错误：BrokenCount > 0’。这通常意味着您安装的软件包有未满足的依赖关系”。
有什么建议可以帮你摆脱这种困境吗？非常感谢。

我终于解决了这个问题。存在循环依赖关系：ia32-libs-multiarch:i386 依赖于 libsane:i386，反之亦然。apt-get 拒绝删除其中一个，因为它依赖于另一个。此外，如果您在同一命令行上同时指定两者，它也会拒绝删除它们。例如：
sudo apt-get remove libsane:i386 ia32-libs-multiarch:i386

Package libsane:i386 is not installed, so not removed
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies.
ia32-libs : Depends: ia32-libs-multiarch
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
然而它将要如果您在同一个命令行上指定它们，则允许您安装它们：
sudo apt-get install libsane:i386 ia32-libs-multiarch:i386

ia32-libs-multiarch:i386 is already the newest version.
The following packages were automatically installed and are no longer required:

Use 'apt-get autoremove' to remove them.

之后一切恢复正常，我可以再次删除 ia32-libs-multiarch:i386。
答案2
好的，让我们逐一修复您的错误：
删除 teamviewer 及依赖项：
sudo apt-get --purge autoremove teamviewer*删除任何
ia32-libs包：sudo apt-get --purge autoremove ia32-libs*我相信你有一个 64 位系统，因此
libsane必须使用 32 位：sudo apt-get --purge autoremove libsane:i386修复任何其他问题：
sudo apt-get update sudo apt-get -f install验证一切是否正确：
sudo apt-get check如果在最后一步您发现的问题与您现在面临的问题不同，请提出另一个问题。
