Ubuntu v24 Host Setup

Here are the minimal steps to setup a clean Ubuntu VM.

Update Packages

Do this before anything else, to ensure the latest package versions are used.

sudo apt-get update && sudo apt-get upgrade -y

Net Tools

We will install net-tools on each host, for diagnostic purposes.

sudo apt install net-tools

Hostname

To set it, use this:

sudo hostnamectl set-hostname new-hostname (replace new-hostname)

Once set, confirm it with the previous command.

Now, you need to update the hostname in your hosts file, with this: 

sudo nano /etc/hosts

The hosts file lists the hostname in the second entry: 127.0.1.1, like this:

Update the 127.0.1.1 entry with the correct hostname.

Save and close the hosts file after update.
