Issue
I'm trying to add universe as a repository in my docker image:
RUN add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) universe"
RUN apt-get update
it errors with this output:
Step 4/24 : RUN add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) universe"

My Docker file uses FROM python:2.7-slim as a base.
What am I doing wrong?

Solution
Since you're using debian as base OS image, then you cannot add ubuntu's repository as mentioned by Tarun Lalwani in comments.
