Build fails when building using the Docker container of ARMNN build tool

[vincentwan-mythic]

I am on the main branch (2b61cecc9df7a43fca1463795062cf359e6be820) and built armnn according to the instructions after installing Docker:
/home/user/armnn/build-tool$ docker build --build-arg SETUP_ARGS="--target-arch=aarch64 --all" --build-arg BUILD_ARGS="--target-arch=aarch64 --all --neon-backend --cl-backend" --tag armnn:aarch64 --file docker/Dockerfile .

This resulted in an error:

Is there something I am missing? I would have expected the container to build since I am running docker build per the documentation.
