Add the winehq source of ubuntu18.04. winehq does not support debian10, while deepin20.8 is based on debian10. I tested that 18.04 and debian10 are the closest, so you can use the winehq source of 18.04 to install, but after you install, you must delete the wine source file. Because of the translator I use, the translation and display results may be different.

This is the wine software source of Debian 10, but it does not support winehq8.0.

Add command

sudo wget -nc -P /etc/apt/sources.list.d/ https://dl.winehq.org/wine-builds/debian/dists/buster/winehq-buster.sources

Or you can install the flatpak version of winehq
