I am trying to build a new image "first" with a docker file. However, it throws an error with the second line of docker file when I try to build the image.
This is my docker file:
FROM ubuntu:18.10
RUN apt update && apt install -y python3
This is the error message I get:
C:\Users\82104\Desktop\ExerciseFiles>docker build -t first .
