我正在尝试从 18.04 升级到 20.04，但每次升级都失败。这似乎是 Python 的问题，但我不知道如何修复它。
这是 apt.log 文件。

当我运行 apt dist-upgrade 或 upgrade 时，我没有看到任何损坏的软件包或其他问题。我删除了 python-dev（根据在其他地方找到的建议），但没有效果。我还删除了 nodejs（同样根据在其他地方找到的建议），但没有效果。
这很像所描述的错误这里，但该线程说问题已得到解决，而我这边的情况并非如此。
任何建议，将不胜感激。
答案1
我通过以下方式解决了该问题（两次，在不同的计算机上）：
sudo apt remove python-dev
然后执行do-release-upgrade。
升级将几乎完成，但在某些时候它会因包裹损坏而停止。
然后，我手动编辑了文件，将第 81 行的/usr/share/pyzo/pyzo/yoton/clientserver.py参数名称更改为，以及下面两三行使用该参数的位置。然后我运行和，升级正确完成。asyncassyncapt --fix-broken installapt dist-upgrade
