Answer 1

I had to fix this issue on a debian based server

this was due to the system use of openssl (curl depends on openssl)

here is how it went:

1. remove AddTrust_External_Root.crt from your system (usually found in /etc/ssl/certs)
   2. remove or comment the "mozilla/AddTrust_External_Root" line from /etc/ca-certificates.conf
   3. run sudo update-ca-certificates to update the certificates used by openssl

maybe it can help you ?
