Comment 2 for bug 2017196

I'm not sure what the intended configuration of these two packages is. On one (older) lunar system I find neither installed. On a fresh lunar install however I find pipewire-alsa but no pulseaudio. Neither package is seeded so it seems either of those configurations is valid.

They do definitely conflict though so I recommend manually removing 'pulseaudio' and then reattempting the upgrade.
