Can't install wine stable on Ubuntu 19.10 (depends on wine-stable)

I am trying to install wine on my Ubuntu 19.10. Actually, I am coming from Ubuntu 19.04, but I upgraded to 19.10 in November.

Long story short, I know of this repository which should contain everything I need to make a proper installation: deb https://dl.winehq.org/wine-builds/ubuntu/ eoan main

The problem is that when I try to do the installation apt install winehq-stable, apt throws an error and stops:

winehq-stable : Depends: wine-stable (= 5.0.0~eoan)

I have double checked if there are some old wine repositories, but there are not. I have checked for previously installed wine packages (using synaptic, searching for "wine"), and found nothing.

I have followed a few guides, but I still can't do the installation.

I am stuck in a dependency hell, but how do I find the cause?

EDIT: Wine installation on Ubuntu 19.10 is different from any previous release, because, they say, libfaudio0 was not available on Ubuntu's repositories prior to 19.10. So old questions or instructions suggesting to use external repositories are outdated.

This is what I did:

• By following a few (outdated, but I didn't know that) guides, I have tried to install wine using old repositories. It didn't work.
  • When I have found out that Ubuntu 19.10 had different instructions I have cleaned up my sources.list, so now I don't have those old/wrong repositories anymore.
  • I have tried to manually remove every package that I have found on my system that could be related with wine.
  • At this point, I thought that my system was cleaned of all of the previous attempts. I was wrong.

• So I have tried a new installation with the official instructions:

  sudo dpkg --add-architecture i386
  wget -nc https://dl.winehq.org/wine-builds/winehq.key
  sudo apt-key add winehq.key
  sudo apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ eoan main'
  sudo apt install --install-recommends winehq-stable
  

And this is the complete output:
