So, when I finally got in, you can imagine my shock working on the terminal with this long hostname “HP EliteBook x360 1030 G2” staring at me. I struggled to find my way around it, but that wasn’t till after I’d used that lengthy hostname for a while. Now, you may not have fallen for the “Ubuntu computer name set as hostname” predicament like I did. Maybe you have a really cool hostname already, but just want to change it for whatever reason, and you’re unsure how. Fortunately, this can be easily done from the Ubuntu GUI or the terminal, whichever method you fancy. In this guide, we’ll show you both methods step by step, so you can pick whichever feels right for you.

Clear the input and enter the new name for your device, and hit the Enter button. Then quit the settings app. ![](https://storage.ghost.io/c/c1/a6/c1a6d111-d951-41ad-a392-c1e841210b93/content/images/2025/05/image-15-1.png) ## How to change your Ubuntu Hostname using the terminal ### Step 1 (Optional): Your hostname is saved in the etc directory. To confirm, run "ls /etc -la" to find the hostname. ![](https://storage.ghost.io/c/c1/a6/c1a6d111-d951-41ad-a392-c1e841210b93/content/images/2025/05/image-16-1.png) ### Step 2 (Optional): Now that we've confirmed we have a hostname folder, to see its information, run "hostnamectl" ![](https://storage.ghost.io/c/c1/a6/c1a6d111-d951-41ad-a392-c1e841210b93/content/images/2025/05/image-17-1.png) ### Step 3: To change the hostname, run "hostnamectl set-hostname 'preferred-name'". To confirm the change, run the "hostnamectl" command to see your hostname details. NB: Your terminal will still have the old name until you refresh or close it. ![](https://storage.ghost.io/c/c1/a6/c1a6d111-d951-41ad-a392-c1e841210b93/content/images/2025/05/image-18-1.png) ### Step 4 (Optional): Update the hostname in the hosts file. This is good because the hosts file maps IP addresses to domain names. To see the details, run "cat /etc/hosts" ![](https://storage.ghost.io/c/c1/a6/c1a6d111-d951-41ad-a392-c1e841210b93/content/images/2025/05/image-20-1-1.png) - Open the hosts file with the command "sudo nano /etc/hosts." Some people open it with just "nano /etc/hosts," which is fine, but this may be an issue if you don't have write access. ![](https://storage.ghost.io/c/c1/a6/c1a6d111-d951-41ad-a392-c1e841210b93/content/images/2025/05/image-26.png) - You'd see that your old hostname is still mapped to your IP address. ![](https://storage.ghost.io/c/c1/a6/c1a6d111-d951-41ad-a392-c1e841210b93/content/images/2025/05/image-21-1.png) - Now just change the hostname and save the file, then exit. ![](https://storage.ghost.io/c/c1/a6/c1a6d111-d951-41ad-a392-c1e841210b93/content/images/2025/05/image-23-1.png) To confirm the change, run the "cat /etc/hosts" command again ![](https://storage.ghost.io/c/c1/a6/c1a6d111-d951-41ad-a392-c1e841210b93/content/images/2025/05/image-25-1.png) [How to Change the Default Text Editor on LinuxEasily change your Linux Text Editor to your preferred editor at any time.![](https://storage.ghost.io/c/c1/a6/c1a6d111-d951-41ad-a392-c1e841210b93/content/images/icon/techloy-avatar-1-1660.png)TechloyOyinebiladou Omemu![](https://storage.ghost.io/c/c1/a6/c1a6d111-d951-41ad-a392-c1e841210b93/content/images/thumbnail/photo-1629654297299-c8506221ca97-4)](https://www.techloy.com/how-to-change-the-default-text-editor-on-linux/) ### Conclusion And there you have it, changing your hostname in Ubuntu doesn’t have to be a headache.
