I have Jenkins instance that I keep updating as soon as a new version is available.

This time I thought I'll give the Ocean Plugin a try.

After installing https://wiki.jenkins-ci.org/display/JENKINS/Blue+Ocean+Plugin plugin, the Jenkins notification reports two errors :

There are dependency errors loading some plugins:
BlueOcean beta v1.0.0-b11
Pipeline: Model Definition v0.2 failed to load. Fix this plugin first.
Pipeline: Model Definition v0.5
docker-workflow v1.8 is missing. To fix, install v1.8 or later.

I can't find docker-workflow anywhere.
