Installing Conda Packages Inside JupyterHub Notebook

Hi all,

I am trying to install a conda package by running the following cell inside my FABRIC JupyterHub notebook:

`import sys
! conda install -y –prefix {sys.prefix} -c conda-forge ipysheet`

The first time I ran this command, the package installed successfully (I think, although when I try to display the ipysheet widget, it doesn’t display as related to this GitHub issue). But now when I try to do any conda updates or install any new packages, it throws the following error:

`# >>>>>>>>>>>>>>>>>>>>>> ERROR REPORT <<<<<<<<<<<<<<<<<<<<<<

$ /opt/conda/bin/conda install -y --prefix /opt/conda -c conda-forge ipysheet`

Any thoughts on why conda cannot find the ca certificate when it exists inside of the /opt/… path above?

Thanks!
