我不确定我在这里实际上做了什么，但是我无法超越。我似乎无法删除，修复或重新安装该软件包，但一切都因该错误或类似错误而失败。有人可以帮我摆脱这该死的东西吗，我已经尝试了几天了。
谢谢！
解决方法
我今天也遇到了这个问题，python-cryptography也以类似的方式阻止了我。
我在python-cryptography软件包上手动运行pyclean。我是root用户，因此您可能需要在命令前添加sudo

这使我遇到了一系列不同的错误（很可能与您的问题无关。我的系统非常损坏），但是dpkg很高兴可以再次开始工作。试一试

,感谢汤姆，虽然这不是我的问题，但确实使我走了正确的道路。基本上，整个问题是由于某个时候将Python 3.5设置为默认值而引起的，并且显然Debian出于某种原因都找不到解决该问题的方法。当我恢复到2.7时，一切都很好。
