Problem statement
What is the safest baseline way to install Docker on Ubuntu 24.04?
Start by removing older conflicting packages, then add the Docker repository, install Docker Engine and Compose plugin, and verify both runtime and image pull behavior.
On networks where Docker Hub reachability is unstable, it also helps to detect connectivity early and add a mirror only when it is really needed.
What to check
- Remove conflicting legacy Docker packages first.
- Install both Docker Engine and Compose plugin together.
- Check registry reachability and add a mirror only if needed.
