@ajkan001: Actually, I think I did. Apparently, 18.04 needs dnsmasq to be running, whereas 16.04 didn't seem to require the user to even have dnsmasq installed. So, make sure you have dnsmasq installed, using (without quotes) "sudo apt install dnsmasq-base". Sometimes, however, dnsmasq just doesn't want to play nice. In that case, use (again, without quotes) "sudo pkill -x dnsmasq" or "sudo killall dnsmasq" (either one will work), and try again.
PS: I probably should have mentioned something on this bug report before, but I guess I forgot.
