I’m newbie to Linux(Ubuntu) ecosystem, and I had a trouble in pairing bluetooth keyboard; Logitech K380. The device was not showing on the bluetooth list. So, I had to connect it manually. The specs are the following.

How To Solve

  1. Make sure to turn on your keyboard. Press the bluetooth button in or to find new device.

  2. Enter bluetoothctl module in your terminal.

bluetoothctl

If it’s not working, try installing it.

    trust XX:XX:XX:XX:XX:XX

That’s all! You have your keyboard connected to your PC.
