Alternative: Install Docker Desktop for Linux + +Docker Desktop for Linux includes Docker Engine plus additional features: +- GUI desktop application +- Kubernetes support +- Image building and management +- Extension marketplace + +**Installation:** +1. Download `.deb` package from: https://www.docker.com/products/docker-desktop/ +2.
