Ensure that WINE is not installed from the Zorin Repo:
sudo apt remove --purge zorin-windows-app-support
Add the wine Key
sudo mkdir -pm755 /etc/apt/keyrings
sudo wget -O /etc/apt/keyrings/winehq-archive.key https://dl.winehq.org/wine-builds/winehq.key
Add architecture and update sources
sudo dpkg --add-architecture i386
sudo apt update
Add the Wine Repo:
(NOTE: This should be the only wine repository in your sources. Be sure to check that it is the only one in Software & Updates > Other tab)
sudo wget -NP /etc/apt/sources.list.d/ https://dl.winehq.org/wine-builds/ubuntu/dists/focal/winehq-focal.sources
You can check which packages are available in the WIne Focal Staging directory with:
apt policy winehq-staging
Instead of stable; install Wine Staging:
sudo apt install --install-recommends winehq-staging
