Hi @lusamino, you should see this section in your Dockerfile which by default is there but it is commented out. So you should uncomment the whole section, and replace the example packages with the package you mentioned. You should not need to add the sudo
command because this will run as the root
user due to the USER root
command that preceeds it and the root
user already has sudo
privileges. But do let me know if this does not work for some reason.
This is what the example section looks like when uncommented:
USER root
RUN apt-get update && \
apt-get install -y --no-install-recommends \
apt-utils \
vim
USER ${NB_USER}
This is what your section should look like:
USER root
RUN apt-get update && \
apt-get install -y --no-install-recommends \
poppler-utils
USER ${NB_USER}
