I tried installing the tftp-hpa package as per TFTP - Community Help Wiki, but it will not install (not properly at least).

user@host:/etc/default$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04.2 LTS

The apt installation process does not:

1. Create and register the tftp-hda service
2. Create the /etc/default/tftpd-hpa configuration file

I expected those two to happen, but they did not. Where do I go looking for breadcrumbs/logs for this issue?

You missed d while installing the package, i.e., tftp-hpa is TFTP client while tftpd-hpa is the server.

If you run apt show tftp-hpa and read description, you'd see

Description: HPA's tftp client Trivial File Transfer Protocol (TFTP) is a file transfer protocol, mainly to serve boot images over the network to other machines (PXE). . tftp-hpa is an enhanced version of the BSD TFTP client and server. It possesses a number of bugfixes and enhancements over the original. . This package contains the client.

On the other hand, apt show tftpd-hpa would return

Description: HPA's tftp server Trivial File Transfer Protocol (TFTP) is a file transfer protocol, mainly to serve boot images over the network to other machines (PXE). . tftp-hpa is an enhanced version of the BSD TFTP client and server. It possesses a number of bugfixes and enhancements over the original. . This package contains the server.
