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 8.8.8.8
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?
$ sudo apt install network-manager-openvpn-gnome
). Going toSettings > Network > Add VPN
I now have an OpenVPN there as well and using that to set up my VPN no more issues. Can disconnect VPN and have Internet immediately afterwards. For me this was a painless fix.
