I am using org-mode installed by the emacs package system:
org-plus-contrib.  I just updated it this morning:

Org mode version 9.2.6 (9.2.6-elpaplus @ /usr/share/emacs/27.0.50/lisp/org/)

I have no trouble, so far, running this template.  If it is of interest, I
am using this also in directories in my Dropbox folder, from my laptop and
a desktop machine.  I will investigate changes in the template parameters.

I am already thinking of another one,  to capture a file listing and
perhaps enable commenting.  That last bit will stymy me.  In fact it's all
pretty much beyond me, for the moment.   I saw a contributed org function
to do something similar.

Anyway, for now, this template shows promise.  It's already easier to save
quick notes about an ongoing project.  Before org-mode, I used steno.el, to
good effect; org-mode, however, is lightyears beyond steno.

Thank you for the comments.

The use of corrupt manipulations and blatant rhetorical ploys ...---
outright lying, flagwaving, personal attacks, setting up phony
alternatives, misdirection, jargon-mongering, evading key issues, feigning
disinterested objectivity, willful misunderstanding of other points of
view---suggests that ... lacks both credibility and evidence.
