Adaptador Bluetooth não encontrado no Ubuntu 16.04

Question

Desde a minha atualização para 16.04, o SO não encontra mais o adaptador bluetooth. O Laptop é um Acer Aspire V5-573G e tudo que eu posso encontrar sobre o adaptador bluetooth é este: "Bluetooth Qualcomm Atheros Bluetooth 4.0". Aqui estão alguns comandos que eu executei, espero que ajude:

Answer 1

Eu tive o mesmo problema. No meu caso, acho que foi um bug da minha antiga versão instalada do centro de controle da unidade, ou algumas dependências ausentes. Resolvido facilmente atualizando o centro de controle de unidade:

    sudo apt-get install unity-control-center

Espero que possa ajudar.
