I am getting the following error using curl: 

curl: (77) error setting certificate verify locations:
  CAfile: /etc/ssl/certs/ca-certificates.crt
  CApath: none

How do I set this certificate verify locations? Thanks.

I also had the newest version of ca-certificates installed but was still getting the error:

curl: (77) error setting certificate verify locations:
  CAfile: /etc/pki/tls/certs/ca-bundle.crt
  CApath: none

The issue was that curl expected the certificate to be at the path /etc/pki/tls/certs/ca-bundle.crt but could not find it because it was at the path /etc/ssl/certs/ca-certificates.crt.

Copying my certificate to the expected destination by running

sudo cp /etc/ssl/certs/ca-certificates.crt /etc/pki/tls/certs/ca-bundle.crt

worked for me. You will need to create folders for the target destination if they do not exist by running

sudo mkdir -p /etc/pki/tls/certs

If needed, modify the above command to make the destination file name match the path expected by curl, i.e. replace /etc/pki/tls/certs/ca-bundle.crt with the path following "CAfile:" in your error message.
