I have a similar problem to the one reported in this thread., but I'm running Bionic Beaver

My machine is a Dell XPS 13. Wifi is working fine.

In settings -> Bluetooth, I'm told No bluetooth found, plug in a dongle

I've tried to turn the button on the top left corner of the screen from OFF to ON but am unable to do so

The solution below, suggested in in the thread cited above, doesn't do anything

rfkill unblock bluetooth
systemctl enable bluetooth.service
systemctl start bluetooth.service

Here's the output of the various commands requested in other posts:

    @ArkaSantra, there are several solutions in that thread. The accepted one did not work for me. Was that the one that worked for you? – Leo Simon Sep 19 '18 at 15:10
