This is an unsupported release now. Please think to install the next LTS
'Bionic 18.04'

Title:
  Can't connect to WiFi if setting MAC address, RTNETLINK answers:
  Device or resource busy

Status in ifupdown package in Ubuntu:
  Invalid

Bug description:
  If my /etc/network/interfaces settings for wlan0 include a "hwaddress
  ether" line, then running ifup for that interface fails at the very
  end, after successfully authenticating with the access point. Here is
  what happens:

  systemd[1]: Started ifup for wlan0.
  wpa_supplicant[765]: Successfully initialized wpa_supplicant
  sh[737]: RTNETLINK answers: Device or resource busy
  sh[737]: Failed to bring up wlan0.
  systemd[1]: ifup at wlan0.service: Main process exited, code=exited, status=1/FAILURE
  wpa_supplicant[791]: nl80211: deinit ifname=wlan0 disabled_11b_rates=0

  Furthermore, this kind of failure leaves a mess somehow, and
  subsequent attempts to connect lead to "RTNETLINK answers: File
  exists".
