Hi! I'll add some information that might help. As using bluetooth was very important to me (and I had this same problem on 3 different installs of that Ubuntu version), I searched forums and found a solution. Basically I manually downloaded the linux firmware and copied the ar3k folder to /lib/firmware. I followed the following steps from the forum below.
