INSTALL UBUNTU – Server 20.04 LTS

Ubuntu – Linux Distribution flavor and is a very popular distribution for many services and other cool stuff in both IT, software development, and much more. So let us install the go through the steps to install the server version.

Note that the server version is simply a version of Ubuntu that is more customizable for service operation and a more minimalistic version than the desktop version. Since the desktop version contains a bunch of other features that may not be useful in many service applications.

Prepare Image

First, we download the Ubuntu 20.04 LTS server image, it can easily be done by their website. You may have to select option 2, for manual install if using USB as well continue with.

Now Insert your USB device and use the following commands. It will print out all disk devices attached to the system. Try to find your USB device.

fdisk -l

The following is an example of a USB storage device printed by the fdisk -l command

Disk /dev/sdb: 14.45 GiB, 15502147584 bytes, 30277632 sectors
Disk model: DataTraveler 3.0
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x00000000

Device     Boot Start     End Sectors Size Id Type
/dev/sdb1         264 2097415 2097152   1G 83 Linux

Now that we have a USB device and the ISO image, we can use the dd tool. Notice, if using for instance a USB device, then it would be the filename without the digit. Since you want to overwrite the whole USB.

  • bs – How big of chunks it will write
  • if – input file
  • of – output file.

Following is an example of using the DD tool.

dd bs=1MB if=ubuntu-21.04-live-server-amd64.iso of=/dev/sdb_your_usb_name
