This will affect many systems running automated updates and docker. I assume this will affect countless servers.

In interactive mode it says

Repository ... Bionic InRelease changed its 'Label' value from 'Docker CE' to 'Docker EE'

This must be accepted explicitly before updates for this respository can be applied.

Do you want to accept these changes and continue and continue updating from this repository? [y/N]

This breaks updating repositories on ubuntu if you have the docker repository added. Can cause some issues for server configuration

Is this intentional or just an accident?

"We're working on a fix on download.docker.com at the moment. We'll post an update to this issue when resolved (should be shortly). Locking this issue until then to keep the thread length sane. Thanks for your patience."

Comment from one of the Docker team

download.docker.com appears to be down for linux?
