我正在尝试升级Ubuntu 16.04。我不小心运行了以下命令：sudo apt-get purge python3.6因为手动安装python 3.6出现问题，现在一切都会引发错误。

update-manager-core is already the newest version (1:18.04.11.10).
update-manager-core set to manually installed.
You might want to run 'apt-get -f install' to correct these:

你知道该怎么做吗？
您是否尝试过确保没有所需软件包的较新版本。
sudo apt update --fix-missing
以前
sudo apt-get -f install
