Update docker on Debian 10

I try to update docker on Debian, with the following command:

sudo apt-get update --allow-releaseinfo-change

But I got the following error message:

Hit:1 http://asi-fs-n.contabo.net/debian buster InRelease
Hit:2 http://asi-fs-n.contabo.net/debian buster-updates InRelease
Hit:3 http://security.debian.org/debian-security buster/updates InRelease

Reading package lists... Done
E: The repository 'https://download.docker.com/linux/ubuntu docker 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.

From another StackOverflow topic, it seems I must update the file /etc/apt/sources.list.d/docker.list

I tried the following (but it does not work):

deb https://get.docker.io/ubuntu docker main

Noticed that:

Should I change to something like, without corrupting/breaking my operating system?

deb https://download.docker.com/linux/debian docker buster

    I had a similar issue on a VM once. The repo for "https://download.docker.com/linux/ubuntu docker" does not exist and needs to be removed. Unsure why it’s there.

    This worked for me:

    1. open the source list (providing there isn’t external source lists):

      sudo nano /etc/apt/sources.list

    2. remove any lines for "ubuntu" as you are on Debian 10 and save

    3. run sudo apt-get update

    Create the following file:

    $ cat /etc/apt/sources.list.d/docker-ce.list 
deb [arch=amd64] https://download.docker.com/linux/debian buster stable

    Then remove any other download.docker.com entries in /etc/apt/sources.list or /etc/apt/sources.list.d/*

    See Install Docker Engine on Debian. Use the following commands:

    curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

echo 
"deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/debian $(lsb_release -cs) stable" |
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

    The first command will download the gpg key, the second one will adjust your docker.list file.

    Then run sudo apt update
