Here are the screens to install Ubuntu 24.04 on a virtual private server.

You can use your arrow keys to navigate. You can use enter to select an option.

After booting you will need to choose your language.

Choose “Continue without updating.”

Confirm your keyboard configuration.

Leave the defaults of “Ubuntu Server” and continue.

Leave the defaults for the network and choose “Done.”

Do not enter anything for the proxy address and choose “Done.”

Wait for the test to finish and choose “Done.”

Leave the defaults for the disk and choose “Done.”

Leave the defaults on the Storage Configuration screen and choose “Done.”

Choose the red “Continue” option.

Enter your name, server name, username, and password.

For “Your servers name” you will only be able to enter letters, dashes, and numbers. Typically I’ll enter the application name or sub domain.

Ubuntu Pro is a paid for feature used in certain regulated environments. If this is not you, choose “Skip for now” and “Continue“.

Choose “Install OpenSSH server” and “Import SSH key.” Then select your source and install your SSH public key. You should also leave “Allow password authentication to off.

The next screen can be skipped. It will list the snap packages you can install to make the server be ready to perform some function immediately after install. For the purposes of this run-through, we are going to skip that.

In the final screen you will have the details about the install and update. The option to “Reboot Now” will appear when the install is complete. If you are installing version 24.04 it will happen in a few minutes. If you are installing LTS version 22.04 it may take significantly longer. 

Once you choose the option to reboot, you will have to modify the server in the IONOS Data Center Designer. 

In the IONOS Data Center Designer

• Click on the server you created and click on “Storage”
• Then click on the drop down next to the DVD and click “Unmount Image.”

• Change the Boot Device to the hard drive.

• Now click on “PROVISION CHANGES”
• You will need to click on “Confirm” and enter your password.
• Then click on “Resolve” and choose “Linux” and click “OK”
• Then click on “Provision Now”

The sever will now reboot. and you will be able to SSH into your server using your key. 

If you followed our earlier guide, you will only be able to SSH to the server from your home. Make sure to open more firewall rules to match whatever you want your server to do.
