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?
sudo apt-get update
first. If that doesn't help, please [edit] the question to include the full error message. – wjandrea Aug 22 '18 at 16:57
