Unable to install bluetooth

[Jc7tee]

Thanks for making this available @marcin-sielski.

I managed to install the wifi but stuck with the bluetooth installation. Here is the output I obtained:

`sudo apt update

@Jc7tee Thanks for sharing. Yes I know it is mentioned in Known Issues section of the README.md file. It is due to the fact that Edimax released driver for more recent kernels and I have not tried yet to udpate the repository to reflect it for Bluetooth.
