I have a Virtualbox VM running Ubuntu 19.05 Desktop version and the network is managed by NetworkManager. It has two interfaces attached to NAT and HostOnly networks. Due to some reason, I was not able to ping my office site and when I looked up in resolv.conf I see that its a symbolic link auto generated by systemd-resolve. One thing that caught my attention was that the name server was set as below: nameserver 127.0.0.53 The following sequence of steps helped me in resolving this issue: UI NetworkManager --> IPV4 --> Set DNS to Manual and add 1.1.1.1, 8.8.8.8 for dns. Then run the below command sudo dhclient Hope this helps someone out there.
