Starting now, I will be holding new Noetic ros/rosdistro release PRs with a plan to sync ROS Noetic packages to the main apt repo on 2021-09-23. Please comment here if there are any issues I should know about before performing the sync.
The sync from testing to main will happen on Monday September 26th. It was decided to delay it because some of the updated packages are very low level, and were just recently built by the buildfarm. Delaying will give more time to catch any regressions in the testing repo.
