Okay, I'm not sure about the VirtualBox part, but I'm doing a fresh install from a new droplet now
and I'll list the commands I'm using 1 by 1 in order to help resolve your issue.

(btw to use nodejs v12 I usually use nvm, but I don't bother installing node 12 for root, and I will run some BG processes using sudo, which lets them use the existing node (usually 10) and I have not noticed a problem).

ssh in to droplet, get a root prompt

$ apt update && apt upgrade

(get a weird error about Debian stretch being expired, okay, moving on)
