apt-get命令因libpython3.3 unmet依赖而失败
操作系统：Ubuntu 14.04，amd_x64。
apt-get命令如install，remove和purge失败，错误与下面所示相同
但是update和clean等命令工作正常。
不确定如何解决问题。 看看我的终端会议。

显然没有人将不同版本的Python包标记为冲突。 因此， apt-get无法正确解析依赖关系，并以正确的顺序替换，删除和添加包。
作为一种解决方法，您可以在覆盖依赖性问题时手动删除冲突的包。 你可能需要玩一下订单（因为我不知道确切的依赖链在这里），但一般的想法是运行
dpkg -r --force-depends libpython3.3-minimal libpython3.3-stdlib
这可能会导致依赖于Python 3.3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。
