I just upgraded to Ubuntu 18.04 and neither Firefox or Thunderbird will connect to the internet. I can ping 8.8.8.8 just fine. I turned off the firewall and they still will not connect. They connected just fine before the upgrade. I changed the proxy to no proxy and system proxy. Still no luck. What am I missing?

That to me would indicate ISP problems.

The wireless connection is being made. I just verified with the my isp.

It seems to be something in netplan. I created a 01-netcfg.yaml in /etc/netplan and added

nameservers:

        addresses: [8.8.8.8, 8.8.4.4]

Rebooted the box and still am having difficulties with urls.

Any ideas?
