To get Comply running on Lubuntu 18.04 minimal install, I had to:
Download comply-v1.2.6-linux-amd64.tgz
from the Comply releases page, and ensure it's my executable path:
curl -LO https://github.com/strongdm/comply/releases/download/v1.2.6/comply-v1.2.6-linux-amd64.tgz
tar -xzvf comply-v1.2.6-linux-amd64.tgz
sudo ln -s $PWD/comply-v1.2.6-linux-amd64 /usr/local/bin/comply
Download the latest pandoc 2.x
binary from here because the latest Ubuntu package is 1.19.x
