CondaHTTPError when installing

We are trying to install cryoSPARC and are receiving the following error when trying to install/update python packages:

CondaHTTPError: HTTP None None for url <https://conda.binstar.org/richli/linux-64/repodata.json>
Elapsed: None

An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.
SSLError(SSLError(SSLError("bad handshake: Error([('SSL routines', 'ssl3_get_server_certificate', 'certificate verify failed')],)",),),)

The installation fails at the error. Any ideas on how to fix this issue? We have tried running the installer again as well as rebooting the machine.

This is on CentOS 7 with CUDA8.

Hi,

I believe this post has the solution: Continuous failure of installation

Switching from https to http resolved the issue. Thank you.

Happy to help! We hope you enjoy using cryoSPARC :smile:
