How to Change the Hostname on an Ubuntu 22.04 VPS or Dedicated Server

Ubuntu 22.04 was launched on April 21, 2022. The final release of Ubuntu 22.04 is available and that means everyone can start using it even on production servers. Ubuntu 22.04 has many improvements including faster boot times and bug fixes.

Just like with a brand new computer, setting an Ubuntu 22.04 hostname is a pivotal process. This might sound tricky when it comes to provisioning your VPS server for the first time. Some people might not care about the Linux’s hostname during the initial process. However, this can lead to a lot of confusion if an administrator is logging to different VPS instances.

A hostname should give quick relevant information about the system where one is logged in. This doesn’t come out of the box and most data centres and hosting company will really set some weird hostnames on new Ubuntu 22.04 instances.

A hostname is simply a label that is assigned to a device on a network to distinguish it from the rest of the devices. Or you might refer to the hostname as another name for “Computer Name“. Hostnames play an important role when it comes to resolving common easy to remember names to IP addresses through the DNS service.

You may use any hostname for your Ubuntu 22.04 server but most people name it after planets or even animals and others will pre-fix the location of the server on the name .e.g New_York_Pluto, Miami_proxima_b.

In this guide, I will show you how to change the name of your Ubuntu 22.04 server.


  • An VPS server running Ubuntu 22.04
  • A non-root user with sudo privileges
