About updates and upgrades

I don't use Ubuntu but Arch and I have no problem to pair with a Bluetooth device. I do not use a smartphone. I have an audio system and headphones and they are paired with my laptop and all works. I didn't have any problem with my friends' phones too. In Ubuntu it could be different compared to Arch. There enough info on the web about it. First, you have to be sure that you have all the packages installed and the service is running. Try this guide for example: https://www.maketecheasier.com/setup-blu...-in-linux/
