After installing Ubuntu 18.04 LTS dual boot the bluetooth doesn't work. When I use windows it works perfectly.

I have been struggling with ths problem for a long time and tried solutions from: ubuntu 18.04 LTS bluetooth [0cf3:3004] discovery not working "No Bluetooth found Plug in a dongle to use Bluetooth"

Any help is deeply appreciated. Thanks!

Some info about my system

Laptop Acer R13

Shutdown your system. It should work after boot.
