dpkg-query：未安装包“python-meep”

Question

似乎我的 python3 实例（在 Kubuntu 虚拟机上）要求安装 meep 作为其他软件包安装过程的一部分。该安装失败，现在每次我尝试安装软件包时都会收到与 meep 相关的安装错误。例如，这只是今天发生的。

自动删除清除或删除没有任何效果。更新和升级没有奏效。我无计可施。除了撕掉python并重新安装所有东西之外，有没有人有任何建议？

我的系统也遇到了同样的问题。我做了一些很可能不推荐的事情。除了冒险，我别无选择。如果您遵循以下程序，您也将承担风险。但是，唯一可以保证的是它对我有用。

有罪的包是python3-meep。它可能在没有在内部更改包名称的情况下进行了升级。这是我确认问题的地方。搜索显示该问题已在 Debian 中报告并修复。进入 Ubuntu 可能需要一些时间

$grep python-meep /var/lib/dpkg/info/python3-meep.*
/var/lib/dpkg/info/python3-meep.postinst:  pycompile -p python-meep
/var/lib/dpkg/info/python3-meep.prerm:  pyclean -p python-meep 
/var/lib/dpkg/info/python3-meep.prerm:  dpkg -L python-meep | grep \.py$ | while read file

所以在文件中

• /var/lib/dpkg/info/python3-meep.postinst 我将python-meep 的出现替换为python3-meep。
• /var/lib/dpkg/info/python3-meep.prerm 我用python3-meep 替换了两次出现的python-meep。

然后我可以删除python3-meep

$ sudo apt-get remove python3-meep

如果有人指出更清洁的方法，我将不胜感激。
