I wouldn't suggest in the example to install Docker 24, as it's not supported for ECE 4.0.0.
I'd suggest Docker 26 or 27 based on the support matrix.


```sh
sudo apt install -y docker-ce=5:24.0.* docker-ce-cli=5:24.0.* containerd.io

Same as before, better to leave a supported example (like Docker 26 or 27).
