Hello, same problem (Message #34) is also here on Debian 11 (bullseye); all its dependencies and recommended packages are installed, system is up-to-date, all GNOME and tracker services are enabled/active, and tested on GNOME Shell on both Wayland and xorg:
> $ gnome-music > Traceback (most recent call last): > File "/usr/lib/python3/dist-packages/gnomemusic/scrobbler.py", line > 81, in _new_client_callback > manager.call_is_supported_provider( > AttributeError: 'NoneType' object has no attribute > 'call_is_supported_provider' currently this bug is tagged as "fixed-upstream" and "Forwarded", it needs to be updated to reflect this problem.
