Yesterday I revised my own installer scripts to deal with a few issues pointed out to me by those who gave them a try. The scripts are focused exclusively on 18.04 and 20.04. They’re just bash scripts; no Python or Ansible.

The source code: Install ERPNext on Ubuntu Bionic 18.04 LTS and Focal 20.04 LTS · GitHub
My goal with those scripts was to create a sort of “didactic” installer … does the job but makes it clear what is going on.
I have opened a new thread to discuss them if you want to try a different type of installer
