If you don't wish to upgrade, but want a fresh installation of Ubuntu 20.04 LTS server on your machine, this guide is for you!

Download the latest Ubuntu 20.04 LTS server edition from here and make bootable USB drive using any one of the programs given below.

Next, configure at least one Network interface card to allow this server to talk to other systems in the network. If you have DHCP server on your network, IP address will be automatically allocated to all available interfaces. If you don't want automatic IP address, choose the network interface using UP/DOWN arrow and configure the IP address manually. After configuring network settings, choose "Done" and hit ENTER to continue.

If your Ubuntu server is behind a proxy server, you need to enter the proxy server details here. Otherwise, simply leave it empty and hit ENTER to continue.

Next, configure the disk layout i.e. partition your hard disk. You will be given tow choices. Choose any one of the given partition methods that suits to you.

  1. Use entire disk : This method will erase entire hard drive and automatically partition the drive. Recommended for newbies. If you choose this option, you can optionally set LVM and encrypt the LVM configuration with LUKS.
  2. Custom storage layout : This is for intermediate and advanced users to manually setup partitions of their choice.

After configuring the storage, choose "Done" and hit ENTER to continue.

If you don't do this now, you can install it later once the installation is completed. SSH is important to access the Ubuntu server from anywhere, so I choose it. Press ENTER to continue.
