What is the difference between docker and docker.io in ubuntu apt repository ? I know docker.io means docker daemon. However, does "docker" have any role?

            From the Ubuntu Packages search page: docker is a system tray for KDE3/GNOME2 docklet applications and docker.io is a Linux container runtime
I did the following search:
- Ubuntu version: xenial
- Term: docker
Exact hits
Package docker
