Hi David,
Are you hosted by HostGator?
If so, that’s an issue related to the local certificate of HostGator.
You can find more information about this specific issue here : https://ww.wp.xz.cn/support/topic/download-failed-problem-with-the-ssl-ca-cert-path-access-rights/
I would recommend you to contact HostGator to solve this issue : “cURL error 77: Problem with the SSL CA cert”
Looking at the wp.org support topic usually updating PHP version should work.
Let me know if there’s anything else I can do for you—I’m happy to help.
ok, I will check with my provider who is not Hostgator however.
or php update, thanks you
resolved with the PHP update.
