[Pkg-utopia-maintainers] Bug#997818: wireplumber: Failed to preset unit, file /etc/systemd/user/pipewire-session-manager.service already exists

[Chris Halls]

Package: wireplumber
Version: 0.4.4-1
Severity: normal

Hi,

I had pipewire-media-session installed on this box and tried an upgrade
of pipewire. pipewire-media-session had to be removed due to lack of
dependencies, but it appears that was not enough to prevent it from
causing an issue with wireplumber:
