blueman-applet crashed with gi.repository.GLib.GError in call_finish(): g-dbus-error-quark: GDBus.Error:org.freedesktop.DBus.Error.InvalidArgs: Unknown action ‘Activate’ (16)

i encountered this problem after upgrading to lunar lobster beta

Status changed to 'Confirmed' because the bug affects multiple users.

As far as I've read, pulseaudio is supposed to be phased out in kinetic, so the fact that we have to turn it back on is a problem too.

I don't think we're supposed to know to turn it back on, something else is broken and that's a workaround... but a maintainer or authority might know better than me.

This bug is also affecting me, but in upgrading to lunar I uninstalled pulseaudio.

I believe the problem may be that lunar doesn't install pipewire-audio, which leaves us with pulseaudio disabled and no bluetooth support in pipewire.

I have 2 clean installs with Xubuntu and Ubuntu 23.04.
Without touching anything special, no package install, I am able to successfully pair my Bluetooth headphones and sound works (tested on Firefox with Youtube).
Unfortunately, for Xubuntu, pairing did not work. I get the same error in blueman-applet.

i have currently installed (by hand):

for audio: alsa-base; pipewire; pipewire-alsa; pipewire-audio; wireplumber.

for audio over bluetooth: Bluez; blueman; pipewire-pulse.

for audio controls: xfce4-pulseaudio-plugin; pavucontrol.

These are the packages needed for audio, bluetooth, and controls.

forget(remove) about pulseaudio; pulseaudio-module-bluetooth;

xubuntu should use pipewire or fix the bug.

I find this same error, but on the Ubuntu Cinnamon 23.10 daily build, running all the latest packages/updates as of 9/14/23 7PM PST.

Steps to reproduce are to install the daily build, run `apt install blueman`, and attempt to run blueman.

It seems like, for me, it happens on the first bootup, and then running blueman again will get it to go, once you successfully connect a device (Bluetooth speaker in my case) it will continue running smoothly. (edit: not the case, it happened once more today simply from trying to open the app from the toolbar icon)

I've attached my blueman crash logs.

I have the same error on Xubuntu 23.10, kernel: 6.5.0-5-generic.

Interestingly it connected to my air pods pro, but it's not able to connect to my old UE Boom 2 (Logitech). Removed pulseaudio and tried some suggestions online, but nothing worked.

The bluetooth-applet error is: br-connection-canceled

Pairing seemed to work, but might be faulty.
The behavior is: It connects, disconnect three times

(on 24.04 the same bluetooth device works fine)
