Thanks for the logs, looks like the problem in your case is quite different:
WARNING: ifup -a is disabled in favour of NetworkManager.
  Set ifupdown:managed=false in /etc/NetworkManager/NetworkManager.conf.

Editing /etc/NetworkManager/NetworkManager.conf and setting managed to false should solve your problem.

The NetworkManager ifupdown control is quite experimental and not really supported, so setting it back to false is recommended.
