I am a brand-new Ubuntu Linux 20.04 LTS VM user. By default, my server name to ‘localhost’ during cloud installation, but now I would like to change the computer name to ‘ubuntu-2004-nixcraft’. Can you tell me how do I remove the localhost and set it to ubuntu-2004-nixcraft on Ubuntu 20.04 Linux? How do I change the Ubuntu computer name from ‘localhost’ to ‘ubuntu-2004-nixcraft’? Can you tell me more about Ubuntu Linux change hostname command?

One can use the hostnamectl command to view or set the Ubuntu 20.04 LTS server’s host name. The host name or computer name is usually at system startup in /etc/hostname file. Open the Terminal application and type the following commands to set or change the hostname or computer name on Ubuntu.
