This is a minor name bug. If I want to start the command "docker" in bash and docker.io is not installed, It recommends to install docker: "sudo apt-get install docker" - This is not the right package name. The docker command is associated with the "docker.io" package. So It has to recommend "sudo apt-get install docker.io".

Thanks for taking your time to report this issue and help making Ubuntu better.
When attempting to run docker without having it installed on Ubuntu 16.04, I get the following message:
$ docker
Programmet «docker» er ikke installert. Du kan installere det ved å skrive følgende:
sudo apt install docker.io
It now recommends to install the correct package, so I believe this can be marked Fix Released. If you need a fix for the bug in previous versions of Ubuntu, please perform as much as possible of the SRU Procedure [1] to bring the need to a developer's attention. Though as you mention, this is a minor issue.
