Lost bluetooth functionality after upgrading from 17.04 to 17.10

Question

A day ago or before I updated from 17.04 to 17.10, I was able to connect my computer with my headphones via bluetooth. Now I can't. I thought maybe I needed to install Bluetooth Manager and Bluetooth Adapter from the Software manager, but this didn't help. Can someone suggest some code I can use through the terminal to reinstall the bluetooth drivers or whatever isn't working so I can get back to using the bluetooth function on my computer? On the settings, Bluetooth, it says plug in a dongle to use bluetooth now. It didn't say this before.

can you post the output of sudo service bluetooth status and dmesg | grep -i blue — Legolas, Oct 26 '17 at 16:36

I've upgraded Kubuntu from 17.04 to 17.10 yesterday.

Mostly the same issue for me, I'm no longer able to connect my bluetooth speaker (RYGHT TANK) even though my bluetooth service is running.

Here is my sudo service bluetooth status and dmesg | grep -i blue results:

A print screen of the message after trying to connect: connecting failure

Any idea?

EDIT (11/05 got it!): I ended up with a solution:

sudo apt install kmix
reboot

then

sudo apt install pulseaudio-module-bluetooth
reboot
pactl load-module module-bluetooth-discover

(last command may fail)

Then remove all your saved bluetooth devices and pair them again.

Do not forget to set the bluetooth devices at the top of the list of audio configuration:

I cannot edit my message to add just "Hi" at the beginning of my question, so I say it here:Hi! — s.aaliy, Oct 27 '17 at 22:29
I have tried again to pair my speaker and noticed a difference on the result of the command sudo service bluetooth status (message edited) — s.aaliy, Nov 05 '17 at 15:57
next step... I've tried to install pulseaudio-module-bluetooth , and I was surprised that it wasn't already installed... anyway, the result is again different — s.aaliy, Nov 05 '17 at 16:11
The problem occured after the upgrade from 17.04 to 17.10. And my bluetooth worked correctly before upgrading. I'd say yes, it's an upgrading bug, at least in my case. — s.aaliy, Nov 05 '17 at 17:56
