I am trying to create a VirtualBox linux virtual machine on which I want to mainly run Wine to install a windows application.
I managed to install Lubuntu 18.04.2, since it is the lightest Ubuntu Distro, but the exported .ova file from VirtualBox is 1.9GB. I am planning to share this VM with other people. So, 1.9GB is a lot to download.
I checked this website (enter link description here) and there is a Lubuntu 18.04.2 VM which has a size of 899MB. How did they do that?
