[docker] build The Docker container issue

Hi:
I try to build the docker container with command: $ sudo docker build -t opentitan -f util/container/Dockerfile .
Could you help to fix the issue?

the log information like below:


Start by reproducing the reported command, `sudo docker build -t opentitan -f util/container/Dockerfile .`, and inspect `util/container/Dockerfile` alongside the attached build log. Identify the build failure and verify the Docker container builds successfully with the documented command.
