大家好，上周我一直遇到这个奇怪的错误，导致我无法安装新软件。我运行了以下命令：sudo apt install uniconf-tools
之后出现了以下情况：

我尝试通过以下命令解决此问题：sudo apt-get --reinstall install python-debian，但错误再次出现，我无法继续。
这是 sudo apt-get update 的输出：

答案1
我明白了...缺少两个模块（six 和 chardet），我可以使用以下命令下载：
sudo apt install --reinstall python3-six
sudo apt install --reinstall python3-chardet
运行这些，你应该就可以了
