How can I install curl inside my container? – Ubuntu

I have the following Dockerfile

FROM jupyter/scipy-notebook

#RUN apt-get update && apt-get install -y curl

RUN pip install mlflow

RUN pip install sklearn

RUN apt-get update && apt-get install -y curl

When I do

docker build -t mycontainer .

I get

Step 4/4 : RUN apt-get update && apt-get install -y curl
 ---> Running in 5defd9816a22
Reading package lists...
E: List directory /var/lib/apt/lists/partial is missing. - Acquire (13: Permission denied)
The command '/bin/bash -o pipefail -c apt-get update && apt-get install -y curl' returned a non-zero code: 100

I suspect it is something related with not running as a root?
So how can I install curl in my container from the Dockerfile?

EDIT: I applied the answer that I was given.
Unfortunately it did not work

    You’re seeing a "permission denied" error when apt attempts to create /var/lib/apt/lists/partial. This is because your process isn’t running as root; the jupyter/scipy-notebook image is configured to run as non-root user (it runs as user jovyan).

    You can change the user under which commands run in your Dockerfile with the USER directive, like this:

    FROM jupyter/scipy-notebook

RUN pip install mlflow
RUN pip install sklearn

USER root
RUN apt-get update && apt-get install -y curl
USER jovyan

    Note that I’ve made sure to reset the user back to jovyan after running the apt-get command.

    Try to install it with root as it done in official jupyter/scipy-notebook Dockerfile and set it back to $NB_UID: (see user declaration in official base docker image)

    USER root
# Install packages you need:
RUN apt-get update && apt-get install -y curl
# Switch back to jovyan to avoid accidental container runs as root
USER $NB_UID

    Here is the hierarchy of base docker images used by jupyter/scipy-notebook:

    jupyter/base-notebook -> jupyter/minimal-notebook -> jupyter/scipy-notebook
