docker-compose up build failed while reading package list

[lisaran]

Hi, I tried to build the ROS2 packages, but it failed because of a GPG error. I've read the old key has been revoked as part of the measures to deal with a recent security incident with build.ros.org. Do you have any suggestions how to fix this?

Thanks for your help.

Try replacing GPG key on in Dockerfile#L135 with correct key for ROS2. Get key either from build instructions page or forum topic.
