[Pkg-utopia-maintainers] Bug#1020330: pipewire-pulse: Conflict with pulseaudio is badly resolved by apt full-upgrade

[Raphaël Hertzog]

Package: pipewire-pulse
Version: 0.3.58-1
Severity: important
X-Debbugs-Cc: raphael at freexian.com, seb128 at debian.org, deity at lists.debian.org

APT will not let me upgrade pipewire-pulse to the latest version because
I have gnome-core installed. It will prefer to deinstall pipewire-pulse:

$ sudo apt full-upgrade
[...]
The following packages were automatically installed and are no longer required:
  libappstream-glib8 libatk1.0-data libmalcontent-ui-0-0 libnautilus-extension1a libqpdf28
Use 'sudo apt autoremove' to remove them.
The following packages will be REMOVED:
  nautilus-extension-brasero pipewire-pulse
The following packages have been kept back:
  python3-twisted-bin tryton-client
The following packages will be upgraded:
  gstreamer1.0-pipewire libpipewire-0.3-0 libpipewire-0.3-modules libspa-0.2-modules nautilus
  nautilus-data pipewire pipewire-bin

If I try to force install pipewire-pulse, it will propose to remove
gnome-core:
$ LANG=C sudo apt install pipewire-pulse

The only way to get the latest version is to manually provide the working
solution by indicating that we also need libspa-0.2-bluetooth (to satisfy
gnome-core's "pulseaudio-module-bluetooth | libspa-0.2-bluetooth" together
with its "pulseaudio | pipewire-pulse").

$ LANG=C sudo apt install pipewire-pulse libspa-0.2-bluetooth

That looks like it will be a disaster for users doing a dist upgrade.
But I'm not sure what we can do about it.
