Problem Description

When executing the Task install dependencies I receive following error within the DevContainer about a custom package:

Modifiations

• In the Dockerfile: FROM althack/ros2:foxy-dev -> FROM althack/ros2:galactic-dev

If you're looking for the galactic version you should use that branch.

More than just the dockerfile should be changed to appropriately use this template with another version of ROS2 ( see the diff )

Closing this for now. Feel free to re-open if you have additional issues.
