/etc/systemd/user/pipewire-session-manager.service already exists and is 
a symlink to /lib/systemd/user/pipewire-media-session.service.

That looks like a debian bug, not an upstream one, 
pipewire-media-session package should cleaned up that symlink on purge, 
but here, the package is "just" removed.

That also looks RC to me, leaving a dangling symlink is never good, not 
too sure how to fix this.
