I couldn’t get it to work.
Travis replied to my plea and gave some more resources, which I hadn’t looked at before.
Here is a current guide that covers your target OS: https://www.digitalocean.com/community/tutorials/how-to-install-linux-apache-mysql-php-lamp-stack-on-ubuntu-16-04 As for Redmine, I noticed that Docker has an official Remine repository: https://hub.docker.com/_/redmine/ I see that it is based on Debian, but that is not too different from Ubuntu. Perhaps the Dockerfiles might be helpful reference, and you can always execute a shell in a container and check out the install.

Got it. I offered to hire a guy on upwork and he helped me get it sorted even before I actually provably could pay him.
