  I have installed the nightly image of Kubuntu Bionic from 25th of April.

  Workaround:
  sudo systemctl disable systemd-resolved.service
  sudo service systemd-resolved stop
- sudo rm /etc/resolv.conf 
- sudo nano /etc/NetworkManager/NetworkManager.conf 
-   >> add "dns=default" under [main]

+ sudo nano /etc/NetworkManager/NetworkManager.conf
+   >> add "dns=default" under [main]
  sudo service network-manager restart
  
+ Then I can connect to the WIFI and I see the login page in Firefox.
