Hi,

I'm trying to install system level package "Poppler-utils" for the cluster. I added the following line to the init.sh script.

sudo apt-get -f -y install poppler-utils

I got the following error: PDFInfoNotInstalledError: Unable to get page count. Is poppler installed and in PATH?

If I install the same line at the notebook level, I don't get this error. 

Can anyone help me with this issue and how to install system level packages at the cluster level in init scripts?
