I’m starting to do development to look at the CN913x SOM on the clearfog development board. The first step is rebuilding all the software.

(Bash)% docker build --build-arg user=$(whoami) --build-arg userid=$(id -u) -t cn913x\_build docker/  
Sending build context to Docker daemon 2.048 kB

The command ‘/bin/sh -c go mod download’ returned a non-zero code: 1

This is the first line in the [GitHub - SolidRun/cn913x\_build](http://github.com/SolidRun/cn913x_build) instructions.

Any suggestions?
