I have tried to build a developer container off the 9.2.5 branch, but the build fails with

Step 24/122 : RUN go build -ldflags "-X \"main.ImageCreated=$(date --iso-8601=seconds)\" -X \"main.ImageRevision=$IMAGE_REVISION\" -X \"main.ImageSource=$IMAGE_SOURCE\" -X \"main.ImageTag=$IMAGE_TAG\"" ./cmd/runmqserver/
