我已经设法在我的 Debian 系统上做了一些事情 Python-Cryptography 不允许我安装或删除任何东西

这是 apt update / apt upgrade / apt dist-upgrade 的结果

我不太确定我在这里到底做了什么，但我无法忘记它。我似乎无法删除那个包，或者修复它，或者重新安装它，一切都因为那个或类似的错误而失败。谁能帮我摆脱这个该死的东西，我已经试了几天了。

谢谢！！！

Answer 1

我今天也运行加入了这个，python-cryptography 以类似的方式阻止了我。

我在 python-cryptography 包上手动运行 pyclean。我是 root，所以你可能需要在命令前添加 sudo

/usr/bin/pyclean python-cryptography

这让我遇到了一组不同的错误（很可能与您的问题无关。我的系统非常坏了），但 dpkg 很高兴再次开始工作。试一试

Answer 2

谢谢汤姆，虽然这不是我的问题，但它确实引导我走上了正确的道路。基本上，这整个问题都是因为我在某个时候将 Python 3.5 设置为默认值而造成的，显然 Debian 出于某种原因无法找到处理该问题的方法。我一回到2.7，一切都很好。
