Installation with singularity

Dear developers, I'm trying to run the colabfold container as specified here: https://github.com/sokrypton/ColabFold/wiki/Running-ColabFold-in-Docker

However, I'm having issues setting my cache directory:
singularity run -B /home/isaac12/scratch/colabfold_cache:/cache colabfold_1.5.3-cuda11.8.0.sif python -m colabfold.download

Traceback (most recent call last):

OSError: Could not find a suitable TLS CA certificate bundle, invalid path: /etc/pki/tls/certs/ca-bundle.crt

I wonder if you have any suggestions in this regard.
Thanks for your support!

Start with the linked Running ColabFold in Docker wiki page and the shown Singularity command, then inspect the traceback through colabfold/download.py and its requests call. Reproduce the missing CA bundle error in the container and determine the installation guidance or configuration change needed for the cache download to complete.
