In Ubuntu 19.10, bluetooth stopped working. I will try to enable it in the
settings, but nothing happens.

When I try to turn it on using bluetoothctl, nothing comes out of the
console either.
``` bash
andrei@HP-Laptop-15:~$ bluetoothctl
Agent registered
[bluetooth]# block
Missing device address argument
[bluetooth]# list
[bluetooth]# devices
No default controller available
[bluetooth]# version
Version 5.50
[bluetooth]#
```
``` bash
andrei@HP-Laptop-15:~$ hcitool scan
Device is not available: No such device
andrei@HP-Laptop-15:~$ hcitool -i dev
Invalid device: No such device
andrei@HP-Laptop-15:~$
```
``` bash
andrei@HP-Laptop-15:~$ rfkill list
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
3: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
```
The most interesting thing is that in Ubuntu 19.04 everything worked
perfectly.
