Using the core18 image from
Kernel snap: 4.15.0-39.42 (72)

rfkill shows there is an hci0 device:
$ rfkill list
0: hci0: Bluetooth
 Soft blocked: no
 Hard blocked: no
1: phy0: Wireless LAN
 Soft blocked: no
 Hard blocked: no

But bluetoothctl does not detect any controller:
$ sudo bluetoothctl
08:58 Agent registered
08:58 [bluetooth]# list
[ output...]

If you revert to the 4.4 kernel [4.4.0-1106.111 (76)] it works:
$ sudo bluetoothctl

Agent registered
[bluetooth]# list
Controller 00:00:00:00:5A:AD BlueZ 5.47 [default]
