当我运行自动 Ubuntu 软件更新时，我收到以下消息（见下文）。我在安装操作系统时自己安装了 Python 3.7：所以我的电脑上同时安装了 Python 3.8 和 3.7。到目前为止，我没有遇到任何问题。您能帮我完成我必须遵循的流程吗？这似乎是 focal1 和 focal3 版本的问题？
The package system is broken
Check if you are using third party repositories. If so disable them, since they are a common source of problems.
Furthermore run the following command in a Terminal: apt-get install -f
Transaction failed: The package system is broken
