Download Ubuntu 20.04 ISO Image
Use the following link to download the Ubuntu 20.04 live server install ISO image, which is provided only for 64-bit systems.
After downloading the ISO image, you need to create a bootable DVD using Rufus tool or a bootable USB drive using the Unetbootin LiveUSB Creator.
Install Ubuntu 20.04 Server Edition
1. To kickstart the installation process, place the bootable CD/DVD into a drive or USB in a port on your machine. Then boot from it by pressing your computer’s boot key (which should be one of
F12 depending on the manufacturer settings).
Once the system has booted, you will land on the installer welcome interface shown in the following screenshot asking you to select the installation language. Press Enter to continue.
2. Next, select your keyboard layout and press Enter to proceed.
3. If your system is connected to a network, it should receive an IP address from your DHCP server. Press Done to continue.
4. Based on your network set up, if you need a proxy server to connect to the internet, enter its details here. Otherwise, leave it empty and press Done.
5. Next, you need to configure the Ubuntu archive mirror. The installer will select it automatically based on your country. Press Done to proceed.
6. Now its time to configure your storage. You need to create the storage layout as explained below. For this guide, we will show how to do this manually, therefore, go to Use an entire disk and then select check the option Set up this disk as an LVM group.
Note that the installer will create the root partition (with a small size by default), then you can manually edit its sizes and also create a swap partition.
The following screenshot shows the default file system summary. Our test machine has a total of 80 GB hard disk capacity.
Creating/Editing Root Partition Size

Note: If you do not want to create a separate
/home partition, skip the next step, head over to create a swap partition.

10. Next, you need to create a home partition for storing user files. Under AVAILABLE DEVICES, select the LVM volume group and press Enter. In the partitioning options, scroll down to Create Logical Volume.

well done installation of Ubuntu.
What is the purpose and benefits of reconfiguring the disk into the mentioned partitions?
Hi, I am not sure what I did wrong. But after following this, I started to follow your LAMP setup and this happens:
I have the Ubuntu 19.04 DT installed. I wanted to upgrade to 20.04 but when I ran the Installer it tells me that it will take many hours. After waiting overnight nothing happened. This went on for three attempts. I do have a fast internet connection
I am frustrated and I have downloaded the ISO version of 20.04. Can I go ahead and install the 20.04 directly from this? I know that I have to put it on a flash drive first.
When I try to install MATE on Ubuntu Server 20.04 I get GNOME 3. This happens with the packets mate-desktop, mate-desktop-environment and ubuntu-mate-desktop.
Does anyone know what is the difference between ubuntu-live-server and ubuntu-legacy-server?
The main difference is the server installer, Ubuntu Server Live Installer will now provide an option to automatically update itself every time it boots, while the Legacy installer can not auto-update: https://ubuntu.com/blog/ubuntu-server-20-04.
