Trying to get an updated / current version of docker on debian bullseye, I get:
$ sudo apt-get update
...
Ign:14 https://download.docker.com/linux/ubuntu bullseye InRelease
Err:15 https://download.docker.com/linux/ubuntu bullseye Release
404 Not Found [IP: 18.65.229.91 443]
Reading package lists... Done
N: Ignoring file 'docker.list_org' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
E: The repository 'https://download.docker.com/linux/ubuntu bullseye Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
This article seemed to point in the right direction but I couldn't find anything that worked.
How do I get around this?
Update: Checking the docker repository from the error above,
https://download.docker.com/linux/ubuntu/dists
I see sub-directories for many other distributions, but no bullseye
