software installation - On 18.04, package "virtualbox-guest-utils" does not exist

In the past, I've managed to get the virtual box shared folder via the command on trusty and xenial boxes.

$ sudo apt-get install virtualbox-guest-utils

But now on the bionic version - the packages does not even exist yet.

So my question is, how do we share the folder on ubuntu 18.04?

virtualbox-guest-utils exists on bionic in the multiverse repo. Simply ensure you have this repository enabled.

om:~$ apt policy virtualbox-guest-utils
