Having network issues
I recently rebuilt my server onto Debian 9, and am having problems with URL resolution.
All I have done is changed my root password, and created an account (adduser sam) which has been added to the sudo group.
This user (sam) cannot resolve domains. The contents of /etc/resolv.conf are
To be clear, I have installed no packages or made any other changes, other than generating an SSH key for sam.
I tried creating a second user to see if that worked, but it didn't
Also found that root user cannot complete an apt-get update as the name resolution for mirrors.digitalocean.com fail - however, it can ping google.com
I've tried rebooting, but no joy - is there some kind of network issue or something?
