Public bug reported: I've recently installed ubuntu 16.04 LTS twice -and i discovered that the problem was from the tool katoolin so i didn't install it- after i installed ubuntu the bluetooth didn't work for me.
P.S:the bluetooth was working when my laptop was ubuntu 15.04 when i turn bluetooth on to connect my mouse the switch was on but it said that Bluetooth is disabled i entered the command sudo rfkill unblock bluetooth it worked but didn't connect to the mouse even after the next restart i also tried to editing the file /etc/rc.local (putting sudo rfkill unblock bluetooth before last line and restarting) and i've tried **sudo hciconfig hci0 reset** with output > Can't init device hci0: Connection timed out (110) my lsusb; rfkill list output: Bus 002 Device 002: ID 8087:0024 Intel Corp.
