When upgrading from one major release to another, such as Docker EE 17.03 to Docker EE 17.06, you need to add the new repository and then follow the installation instructions.
To resolve this issue, add the Docker EE 17.06 repo manually. The repo name varies by platform.
- Go to the Docker Engine installation docs: https://docs.docker.com/engine/installation/
- Click on the platform on which you are upgrading Docker EE.
- Follow the instructions in the SET UP THE REPOSITORY section for your platform.
