Failing at Docker install convience script

[MoreThanWYSIWYG]

I have tried on multiple versions of raspian, debian, and raspberry pi os and always fails with the following:

@jbkel - That's a really long thread—any particular commands or workarounds in it that helped you? You could link to a specific comment or just copy and paste the relevant fix (would help others running into this).

That helped. Specifically:

• Edit /etc/apt/sources.list.d/docker.list
• Change line to: deb [arch=armhf] https://download.docker.com/linux/raspbian stretch stable

I am actually running this on a old Intel NUC and had to change armhf to amd64, but it works well now.
It's running on an old NUC from 2014 using Debian 10. I had to install sudo (which was kind of surprising) and rsync.

I got it installed without problems by downloading the most recent .deb files for containerd.io, docker-ce-cli and docker-ce from here https://download.docker.com/linux/debian/dists/buster/pool/stable/armhf/
and installing them in that order with sudo dpkg -i

System:
Raspberry PI 4
Latest Raspbian Buster
deb files: containerd.io_1.2.6-3_armhf.deb docker-ce_18.09.73-0debian-buster_armhf.deb docker-ce-cli_18.09.73-0debian-buster_armhf.deb
