In this case, we are going to proceed with this tutorial with Windows 10 as the host machine and Ubuntu 20.04 as a virtualized machine in VirtualBox. After some research, I discovered that it wasn't so easy as I thought, so today I will share with all of you how to increase the size of a virtual drive in a virtual box. As I had a lot of important stuff in there, I refused to create a new virtual machine with a bigger drive but instead, research how to make the current Virtual Drive bigger. This was my bad from the beginning as I thought I had 100GB but instead, I created a virtual drive of only 10GB. In the last days, while installing a bunch of packages and applications, the following warning appeared: Usually, for the Ubuntu tutorials that are written on the blog, I test them first on Virtual Machines so I can verify if they will work on the server as well.
