Recently, we wanted to change the hostname of our ubuntu 15.10 / 16.04 machine,
$ lsb_release -a No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 15.10
Release: 15.10
Codename: wily
Lets, check now what is current hostname,
$ hostname new-hostname
So, its set to “new-hostname”
Now, to change the hostname lets say “my-netbook”, user the command as,
$ hostnamectl set-hostname my-netbook
Now, open a new terminal and verify that its changed,
$ hostname my-netbook
So, its now changed 🙂
In certain case, using sudo you might get an error like “unable to reolve host” to resolve this follow “How to Fix : sudo: unable to resolve host my_user: No such file or directory”
