Unable to turn bluetooth on

  • 772

I upgraded my system to ubuntu 17.10. I could turn on my bluetooth and use it normally. But today, I don't know why and how, I can't turn it on. In the top-right I can only press Turn Off open Bluetooth Settings. The Turn Off button doesn't toggle even if I press it. Even when I open the Bluetooth Settings I can't turn it on from there.

Does anybody have a solution?

    I got the same problem today, and found out the problem was related to rfkill. So I tried

    $ rfkill list 
0: hci0: Bluetooth
    Soft blocked: yes   <-- ah ah!
    Hard blocked: no
(...)

    The command rfkill unblock 0 did the trick.

    That being said, I have no idea why all of a sudden I ended up in that state... (or why the UI is not able to detect/fix that problem on its own).
