【问题描述】：
我使用 Parrot OS v4.7，Pyinstaller 出现问题（依赖项问题，但所有依赖项都已完成/安装），所以我搜索并尝试卸载并重新安装 Python3。
我跑了
apt-get remove python3
但它也开始删除其他软件包， 现在电脑工作不正常了。
已删除：
- 配合界面
- 蓝鱼
屏幕截图不工作，它说：
Failed to execute child process “mate-screenshot” (No such file or directory))
仪表板
和许多其他软件包一样，系统无法像以前那样运行。
现在当我尝试重新安装 Python3 以恢复它们时，会发生错误。 它在运行时给出以下输出
当我跑步时
apt-get install python3
或
apt-get install --reinstall python3
我明白了：

请帮我重新安装 Python3 并取回已删除的软件包，以便计算机可以正常工作。
主要是删除了系统包。
