Well I had the problem that bluetooth was always off. I go to configuration->Bluetooth and everytime I tried to put it off just returns to off a while after.
I tried with this command:
aptitude install bluetooth
and then ran
/etc/init.d/bluetooth start
after that I ran /etc/init.d/bluetooth status and this is what shows:
● bluetooth.service - Bluetooth service

My computer is a sony VAIO SVF15A17CLV.
Thank you!!
Edited:
After running the service restart command some of you suggested I got the following output:

Seems better but it is still not working. When I go to bluetooth settings it's always off. After I press start it stays like the following image:
PS: I know is not a hardware issue because if I boot with windows 10 it works properly.

I believe we were having the same problem. My Bluetooth would not turn on and would remain in the off position. Here is what I did to fix this problem:
This restarted the Bluetooth service and I was able to turn it on and it stay on. I was also able to see Bluetooth devices and connect to my headphones again.
