i am building vxros2build and it seems it could be errors on private keys, building stop at step 6. In that case it means it doesn't build everything. If i run the last layer built it prints humble as $ROS_DISTRO at least

Step 6/16 : RUN apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654

Hi @razr , it's me again, i've found in https://answers.ros.org/question/398460/how-to-add-a-pubkey/ that this solution might be old? i've changed with RUN apt update && apt install curl gnupg lsb-release && curl -sSL https://raw.githubusercontent.com/ros/rosdistro/master/ros.key -o /usr/share/keyrings/ros-archive-keyring.gpg as suggested in the official guide

hi again @razr,

Solved many "problems" (i've followed all your instructions) and got this result on distlib module:

cd /work/build/colcon/colcon_ws; \
./src/colcon-core/bin/colcon build --merge-install --install-base=/wrsdk/vxsdk/host/x86_64-linux --paths src/*

[razr]

I'm not sure what you mean by "Solved many problems" Did you successfully build vxros2build:humble docker image? There are two Guthub actions, that you can use as a reference

• docker-build
  • builds both docker images and downloads vxros2build:humble as an artifact
• vxworks-ros2-build
  • makes a complete build cycle (docker images, ROS2 VxWorks build
  • creates and downloads a ros2.img

[enriLoniterp]

Yes i've built the images and inside /work i did:

1. make distclean
2. make

Following errors reported in the initial comment. (echo $ROS_DISTRO printed humble as specificied in docker file). I'll follow your suggests and use first method, but then to install the image in VWorks7 what should i do?

Thank for your support @razr, Enrico
