sudo apt升级不起作用！未满足的依赖项 Python 3

Question

我最近安装了Python3.8，一切正常，在终端中成功使用了各种版本的Python。几天后，我打电话给sudo apt update，效果很好，但是当我这样做时，sudo apt upgrade我收到了下面的错误消息。我尝试这样做sudo apt --fix-broken install，但子进程返回了错误代码。

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
dh-python : Depends: python3-distutils but it is not installed
python3-dev : Depends: python3-distutils (>= 3.6.7-1~) but it is not installed
python3-pip : Depends: python3-distutils but it is not installed
python3-setuptools : Depends: python3-distutils but it is not installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

Answer 1

尝试使用以下内容代替：

sudo apt dist-upgrade 

由于 dist-upgrade 还处理新的包依赖项。

此处对此进行了解释： 为什么使用 apt-get Upgrade 而不是 apt-get dist-upgrade?
