Is there a way to get Wine as a single binary / docker or something that is easy to install?
Edit: As for why it was really difficult is because of that: https://wiki.winehq.org/Debian ( The WineHQ packages for Debian 10 and later require libfaudio0 as a dependency. Since the distro does not provide it for Debian 10, users of that version can download libfaudio0 packages from the OBS. See https://forum.winehq.org/viewtopic.php?f=8&t=32192 for details. ) That bloody libfaudio0.
