Linux 5.15.74-051574-generic bluetooth not showing devices
I have installed the ubunut version 22.04 but my bluetooth is not showing the devices. I tried to fix it with the help of askUbuntu but not found any solution. Please guide me through the solution. I will be appreciate this. I am pasting a link below if you want to see the output of: sudo dmesg | grep -i blue
