Check your system whether it supports DVD burning. Start by opening a terminal window and execution of the bellow command:
```
$ cat /proc/sys/dev/cdrom/info
```
Your system should have at least one hardware device which supports DVD write. Check the output and look for Can write DVD-R. The integer 1 means that the DVD write is supported. Also take a note of the drive name supporting the DVD write. In this case the drive name is sr1 hence the full path to the DVD writer is /dev/sr1.
Next, download the ISO image you wish to burn to DVD. As an example, in this tutorial, we will burn downloaded Ubuntu 20.04 ISO image.
