--- Comment #7 from jkfloris@dds.nl --- I think the easiest solution for now is to change the instructions on the wiki to:
wget -O - https://dl.winehq.org/wine-builds/winehq.key | sudo gpg --dearmor -o /etc/apt/keyrings/winehq-archive.key -
After Debian Bullseye and Ubuntu Focal are EOL, we can add the key to the .sources file. This requires apt version 2.3.10 or higher.
