He means simply removing "trusty + armhf" for the "ros" and/or "gazebo" images, I believe (not for the "ubuntu" image).
The harm this causes is that "apt-get update" fails, which causes the whole "docker build" to fail.

E: Some index files failed to download. They have been ignored, or old ones used instead.
