When attempting to create a droplet on DigitalOcean.com from a snapshot that utilized a full install of the Virtualmin script located here: http://software.virtualmin.com/gpl/scripts/install.sh
None of the userdata from my cloud-config script comes across to the final droplet that runs Ubuntu 18.04. This previously worked on Ubuntu 16.04
However, if I install Virtualmin with the --minimal flag then the cloud-config script works as expected.
I have detailed my troubleshooting thus far in the forum here: https://www.virtualmin.com/node/60754
