Facing problems/ERROR while building sage using docker in wsl (Ubuntu)

[Prashant Choudhary]

Hello Sir, 

I am new to the SageMath and loved it so much. I am good in Mathematics and pursuing graduation in Computer Science and think that I should do some contribution in it .

I read the documentation and working accordingly. But while building I am facing some package related problems. After 2-3 try, I move to the docker to build the sage but it is also showing some problem while building in docker. Please help me and guide me .

Information: I ran the command as shown below and it was executing but at some point it is showing some error and i am unable to understand what are errors please help me.

Program:

              $ docker build --build-arg MAKEFLAGS="-j16" \                                                                           --build-arg SAGE_NUM_THREADS="4" \

             --build-arg ARTIFACT_BASE="sagemath/sagemath-dev:develop" \
             -f docker/Dockerfile \
             --target=make-build \
             --tag sage .
