Error during running the devel job locally: Unable to connect to 54.183.65.232

Guys, I am trying to make a local build to verify some of my changes using the following instruction:

However the generated script devel_job_indigo_roscpp_core.sh can’t connect to 54.183.65.232 and I see the following error:

Reinvoke 'apt update' (10/10) after sleeping 25 seconds

Is the server temporarily unavailable?

Manually changing this generated IP to what ROS jenkins uses http://repositories.ros.org/ubuntu/testing helped to proceed with the task, but still not clear yet for me how this IP was generated when I followed the instruction.

The examples were using the default branch of the buildfarm config repo. This branch does no longer work since it references a test farm which is not available anymore. I just updated the examples to point to the production branch instead which is used by the official buildfarm and will continue to be available: https://github.com/ros-infrastructure/ros_buildfarm/pull/390

The README in https://github.com/ros-infrastructure/ros_buildfarm_config mentions the different branches but the information is bit “hidden” in the text and not easy to discover.

Thank you. Now it works.
