In Case of Docker installation ,just run these commands step by step written bellow;

1. sudo apt-get -y install apt-transport-https ca-certificates curl software-properties-common
2. curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - 2>/dev/null
3. echo -e "\ndeb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable" | sudo tee -a /etc/apt/sources.list
4. sudo apt-get -y update
5. sudo apt-get -y install docker-ce docker-ce-cli containerd.io

Yes, we don't provide packages for that Linux distro; as mentioned above, it's possible that packages for other similar distros work, but we don't want to update the script to automatically "guess" something that "could" work, because no testing/verification is done on those distros, and we try to avoid "pretending" that it's supported / tested. Also see https://docs.docker.com/engine/install/#other-linux-distros

My general recommendation would be to;

• Verify if the packages work for your situation / distro (in a testing environment)
• If they do, and you're comfortable running them on your systems, and if you need to automate setups; create a script based on the steps of this script;
  • you can use --dry-run to see the steps it executes
  • or (as the script largely automates the manual installation steps); base your script on the instructions for the distro you're installing packages for; e.g. https://docs.docker.com/engine/install/centos/

Maybe (to be discussed) we could consider a manual "I know what I'm doing" option that allows overriding these options (e.g. as suggested in https://github.com/docker/docker-install/pull/229, or a --override-distro=xxx flag), but that needs to be discussed.

I'm closing this ticket for now, but feel free to continue the conversation or to open a ticket with a proposal for alternatives.
