Depois de instalar o Ubuntu 17.10, não consigo iniciar o Dilúvio

Question

1. $ deluge --version

   deluge: 1.3.15
   

2. Estava funcionando muito bem antes da atualização do Ubuntu de 17.04 para 17.10; Eu o instalei antes da atualização e tentei reinstalá-lo (muitas vezes) após a atualização com:

   $ sudo apt install deluge
   

3. $ apt-cache policy deluge\* libboost-system\*
