Installing Docker: Docker Desktop, Docker Engine on Linux and the Alternatives
On Windows you install Docker Desktop with WSL 2; on a Linux server you install Docker Engine from Docker's official apt repository, not the distribution's package. With real output we look at the docker.io and Compose v1 trap on Ubuntu 24.04, prove that the docker group really is root, try rootless mode, use docker context to see which engine you talk to, and cover Desktop licensing, alternatives such as Podman and WSL containers, and the amd64/arm64 emulation trap.
