操作系统：Ubuntu 14.04，amd_x64。
apt-get安装、删除和清除等命令会失败，并出现如下所示的相同错误
update但是像和这样的命令clean可以正常工作。
不确定如何解决这个问题。看看我的终端会话。
$ sudo apt-get install --reinstall lightdm

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
libpython3.3 : Depends: python3.3 (= 3.3.6-1+trusty1) but 3.3.2-7ubuntu4 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
$ sudo apt-get -f install -y

显然没有人将不同版本的 Python 软件包标记为冲突。因此apt-get无法正确解决依赖关系并以正确的顺序替换、删除和添加软件包。
作为一种解决方法，您可以手动删除冲突的软件包，同时覆盖依赖关系问题。您可能需要对顺序进行一些调整（因为我不知道这里确切的依赖链），但一般的想法是运行
dpkg -r --force-depends libpython3.3-minimal libpython3.3-stdlib
这可能会使依赖 Python 3.3 的正在运行的应用程序或系统服务崩溃/中断，您可能需要在升级后重新启动它们。
