How to Change Hostname in Ubuntu Server (Step-by-Step
In this video, I show how to change the hostname in Ubuntu Server using the hostnamectl command.
Commands used:
sudo hostnamectl set-hostname new-hostname
Then update:
/etc/hosts
This method works on Ubuntu 20.04, 22.04, and 24.04.
Topics covered:
Check current hostname
Change hostname permanently
Update hosts file
Verify changes
If cloud-init resets the hostname after reboot, I also explain how to fix that.
