In Ubuntu 16.04 I had no problems with VPN: after disconnecting I had Internet.
In Ubuntu 18.04 I have no Internet after disconnecting from the VPN. I can actually ping
22.214.171.124 but not
www.google.com hence I'm thinking DNS related issue.
A manual solution is to do
$ sudo service network-manager reload.
- What is causing the problem in Ubuntu 18.04, and
- How do we fix it permanently?
