Yes. But that's the "workflow execution time", which is not really a meaningful performance number - it's longer than the longest build but shorter than the total build time. When...

My takeaway is that caching in the way I did it isn't worth it. I don't know what you mean by "I still don't see it" but I don't think...

Performance aside, it seems all the flakiness I’m seeing is from azure.archive.ubuntu.com/ubuntu. That url fails for both apt-get update and upgrade. Adding another mirror may be a good idea. https://github.com/ros2/rmw_cyclonedds/runs/551468958?check_suite_focus=true

> Running them in Docker containers on GH action would mitigate those issues Okay. Are these docker containers ready to use today? Or do you mean hypothetically? It would be...

I know how to dig into the data. I was calling out that the top-level error is pretty unuseful. This seems to be a negative consequence of wrapping everything in...

I don't think even parsing output is needed - simply *not* wrapping all executables in a bash shell would suffice.

What's the status of this? Here's a run that failed due (I think) to this issue https://github.com/rotu/colcon-cmake/runs/1022750727?check_suite_focus=true Note that it *is* apt installing `python3-catkin-pkg-modules`, but I think there's some interaction...

Looks like Github environmnets they considered disabling SIP and didn't: https://github.com/actions/virtual-environments/issues/650#issuecomment-610541765 Submitted an issue to clarify REP 2000: https://github.com/ros-infrastructure/rep/issues/259 IMO we need to change ROS to be compatible with SIP,...

I also seem to get a similar issue when trying to convert between unsigned integer types. `uint32(uint64.high)` Note the "-1" in the below error message > stdin(5, 7) Error: conversion...
