[Solved] Android to Ubuntu file transfer over bluetooth shows "Connection failure" error

I got this error while I was trying to transfer the files from my Android phone to my laptop, which have Ubuntu installed. I had the devices paired, but still the file transfer from my phone to laptop would not happen. I have done the following to configure Ubuntu to accept files from bluetooth devices that solved the problem.

Open the Personal File Sharing in the dash and check both the checkboxes under "Recieve Files over Bluetooth" section.
