At a fresh ubuntu install I faced the error:
ubuntu@(none):~$ sudo su –
sudo: unable to resolve host (none)
To solve this check two things:
- That the /etc/hostname file has only the name of the machine and nothing else
- That /etc/hosts has the localhost and the name of the machine
127.0.0.1 localhost
127.0.0.1 my-machine
