I just created my first droplet today. I added an user and give it root privileges. Whenever I "sudo", I get "unable to resolve host [myhostname]". Although my command is executed fine, I still want to get rid of this?
Belows are my /etc/hostname and /etc/hosts
knguyen@knguyen:~$ cat /etc/hostname
knguyen@knguyen:~$ cat /etc/hosts
::1 localhost ip6-localhost ip6-loopback
