Blueman Protocol not available
Today my bluetooth headset stopped working. I haven’t modified anything recently (although a few days ago I was trying to get a bluetooth headset to automatically connect in a2dp mode, which involved installing blueman and re-pairing with it, but I’ve connected and rebooted several times since making that change and everything was working). Now when I try to connect the headset I get:
Connection Failed: blueman.bluez.errors.DBusFailedError: Protocol Not available $ sudo apt-get install pulseaudio-module-bluetooth $ pactl load-module module-bluetooth-discover $ sudo apt-get --purge --reinstall install bluetooth bluez blueman pulseaudio pulseaudio-module-bluetooth $ sudo /etc/init.d/networking restart [ ok ] Restarting networking (via systemctl): networking.service. $ sudo /etc/init.d/bluetooth restart [ ok ] Restarting bluetooth (via systemctl): bluetooth.service. And of course rebooting, but nothing seems to help, and I can’t figure out what protocol it’s talking about, since I can see the headset and pair with it, but not make an audio connection. I’m running Ubuntu 18.04.1. Some other details:

I still have no idea why this is necessary or what the error originally meant.

For me just reloading the module by executing:
pactl unload-module module-bluetooth-discover pactl load-module module-bluetooth-discover Works with 19.04 too. The module must be unloaded first pactl unload-module module-bluetooth-discover .
This is the only thing that worked for me with my Bose 700 headphones using blueman on cinnamon. Didn’t even have to restart bluetooth service and didn’t have to run the commands above as root.
What did work for me was this: (as pointed above by Luca Mattia Ferrari)
$ sudo apt-get purge pulseaudio $ rm ~/.config/pulse && sudo killall pulseaudio $ sudo apt-get install pulseaudio $ pulseaudio --start The above to ensure pulse is working first.
Then, this one, which is a bit weird that doesn’t come by default with pulseaudio itself:
$ sudo apt-get install pulseaudio-module-bluetooth $ pactl load-module module-bluetooth-discover A bit redundant I know, but these were the exact steps worked for me 10 minutes ago.
But OK, at least it works now 🙂
I had the same problem on Linux Mint 20.1 (based on Ubuntu 20.04) and it solved it. Thanks @Winampah.
Just delete the device on bluetooth manager and pair again. Works for me.
Just restarting the pulseaudio worked for me.
None of the above solutions worked for me on Ubuntu Server 20.04. This is what finally did it:
# remove pulseaudio bluetooth module sudo apt-get purge pulseaudio-module-bluetooth # install bluetooth plugins for PipeWire multimedia server sudo apt-get install libspa-0.2-bluetooth # stop or restart the service systemctl --user stop pipewire-pulse.service pipewire.service After this, reconnecting the device works.
If you have change some setting is /etc/pulse/default.pa so I suggest you to replace it with default which is https://pastebin.com/EJ2qvZvA
