Conda update failed: SSL error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed

according to @jreback here https://github.com/conda/conda/issues/1166

conda config --set ssl_verify false 

will turn off this feature, e.g. here

Conda needs to know where to find you SSL certificate store.

conda config --set ssl_verify <pathToYourFile>.crt

No need to disable SSL verification.

This command add a line to your $HOME/.condarc file or %USERPROFILE%\.condarc file on Windows that looks like:

ssl_verify: <pathToYourFile>.crt

If you leave your organization's network, you can just comment out that line in .condarc with a # and uncomment when you return.

If it still doesn't work, make sure that you are using the latest version of curl, checking both the conda-forge and anaconda channels.

This seemed to do the trick for me:

conda remove certifi
conda install certifi

Then you can do whatever you were trying to do before, e.g.

conda update --all
