我犯了一个愚蠢的错误，从 /usr/bin 以及其他文件夹中删除了 python3.9 文件夹（这是一个很长的故事，为什么我这样做）。
当我尝试通过运行重新安装它时，sudo apt install python3.9我在屏幕截图中看到了这种错误。
我不知道这个“blueman”是什么，所以我需要一些帮助来解决它，因为我想要回我的python，但我不知道该怎么做。

答案1
系统仍认为python3.9已安装：
python3.9 is already the newest version (3.9.1-4).
如果您删除了文件而不删除程序包，则这是有意义的。因此，您需要明确地重新安装它：
sudo apt reinstall python3.9
根据您删除的其他文件，您可能还需要重新安装其他软件包。以下是重新安装已安装的所有 Python 包的方法：
sudo apt reinstall $(dpkg-query -W \*python\* | awk '$2 { print $1 }')
