How to change computer hostname on Ubuntu (GNOME)

A hostname is a system’s primary network identifier in Ubuntu. It is used for network communications, remote access, and domain integration. Ensuring a correct and descriptive hostname is vital for smooth connections, organized asset management, and clear system monitoring.

In Ubuntu, the hostname is stored in /etc/hostname and can be managed through the graphical interface, which helps prevent manual configuration errors. The interface provides a straightforward way to modify this setting without dealing with the command line.

Renaming the hostname through the GUI minimizes the risk of misconfiguration. It also helps administrators who prefer a visual workflow or operate within environments that limit terminal access. After renaming, it is often useful to log out or reboot to ensure the new hostname appears in all services.

1. Open the “Settings” application from the activities menu or system tray in Ubuntu.
2. Select “About” from the left panel to view system details.
3. Locate the “Device Name” or “Computer Name” field.
4. Enter the new hostname in the field.
5. Close the Settings window to save the change.
6. Log out and log back in to refresh the hostname in the user interface.
7. Reboot if necessary for the new hostname to propagate to all services.
