Bluetooth.service 'bad unit file setting'

Kelltech · November 4, 2024, 4:02pm

Hello,

Cannot seem to get Bluetooth back up and running. I did reinstall Bluez but no effect, rebooted a few times as well. I’ve also searched here and Arch community but can’t seem to find a similar error or the right fix.

Here are the things I’ve tried and the outputs:

sudo systemctl start bluetooth.service
Failed to start bluetooth.service: Unit bluetooth.service has a bad unit file setting.
See system logs and 'systemctl status bluetooth.service' for details.

sudo systemctl restart bluetooth
Failed to restart bluetooth.service: Unit bluetooth.service has a bad unit file setting.
See system logs and 'systemctl status bluetooth.service' for details.

systemctl status bluetooth.service
○ bluetooth.service

What do systemctl cat bluetooth.service and paclog --package=bluez return?

Kelltech · November 4, 2024, 7:20pm

systemctl cat bluetooth.service
# /etc/systemd/system/bluetooth.service

I just looked at that file and it’s completely blank.

paclog --package=bluez
[/quote]

paclog --package=bluez
[2024-09-27T12:50:25-0500] [ALPM] installed bluez (5.78-1)

Maybe need a downgrade to 5.78-1?

ajgringo619 · November 4, 2024, 7:33pm

That might be necessary. I’m still on 5.78-1. If you’d like, here’s my service file:

Perfect, thank you! I pasted into my service file and was able to immediately restart Bluetooth service. Very much appreciated!
