Theme setup on gitlab receiving this error: cURL error 60: SSL certificate problem: unable to get local issuer certificate

[collinblank]

Trying to connect this with gitlab. Receiving these errors when I debug. Not sure why http request failed or why requested url is different. It's including encoded slash after username (not sure if that's a problem but it's not in my functions.php.

No updates found.
The update checker encountered 4 API errors.

1. cURL error 60: SSL certificate problem: unable to get local issuer certificate
   Error code:
   http_request_failed
   Requested URL:
   https://gitlab.domain.net/api/v4/projects/username%2Fgit-repo/releases?per_page=1
2. cURL error 60: SSL certificate problem: unable to get local issuer certificate
   Error code:
   http_request_failed
   Requested URL:

3. cURL error 60: SSL certificate problem: unable to get local issuer certificate
   Error code:
   http_request_failed
   Requested URL:
   https://gitlab.domain.net/api/v4/projects/username%2Fgit-repo/repository/branches/main
4. Could not retrieve version information from the repository. This usually means that the update checker either can't connect to the repository or it's configured incorrectly.
   Error code:
   puc-no-update-source

It's been a while since I've seen one of these, but I think this SSL error probably means that the certificate bundle on your server is out of date. The bundle file path is usually set by the curl.cainfo or the openssl.cafile option in php.ini. Unfortunately, I can't give you specific instructions for updating the certificate bundle - I'm not very familiar with the process, and it can vary depending on the OS.

Do you know why when we provide the proper URL in the functions file, why the requested URL is different adding /api/v4/projects and adding the encoded "/" (%2F)?

That most likely has nothing to do with the SSL error, but if you're curious:

• PUC requests /api/v4/projects and similar URLs because it's trying to retrieve repository information using the GitLab API.
• Forward slashes in the project and/or repository path were originally URL-encoded to fix this issue: Archive.zip download on Plugin Update with GitLab does not work anymore #240
  • This is mainly necessary to support subgroups, but should also be fine for projects that don't use subgroups.
  • The GitLab API documentation recommends URL-encoding project paths. See the description of the id parameter.
