Just installed a fresh copy of Ubuntu 22.04 LTS on my Lenovo laptop and the entire Bluetooth system doesn't work (I mean the toggle doesn't work). I'm getting the message shown in the below screenshot:
Here is the output of lspci -knn | grep Net -A3; lsusb; dmesg | grep -i blue

I tried everything, but can't make it work. Am I missing something?
