    Change Hostname on Ubuntu 22.04 LTS

    This article is for those looking for a detailed and straightforward guide on chaning hostname on Ubuntu 22.04 LTS.

    In this guide, we will consider the case when you already have a server with the Ubuntu Server 22.04 LTS operating system installed on it.

    You can read more about how to install Ubuntu Server 20.04 LTS in my guide “Install Ubuntu Server 22.04 LTS”.

    In addition, OpenSSH must be installed on the server, and port 22 must be open in order to be able to connect to the server using the SSH protocol.

    To install OpenSSH on a server, you can use the command:

    sudo apt install openssh-server

    If you plan to connect to the server using the Windows operating system, you can use PuTTY or MobaXterm.

    This guide describes how to connect to a server using the iTerm2 terminal emulator installed on the macOS operating system.

    We connect to the server on which we plan to change the hostname.

    Let’s check the current name of the server name using the command:

    hostname
