It seems to me that a package has been updated and certificates are now
missing.
This line always seems to appear:
ssl.SSLError: [X509: NO_CERTIFICATE_OR_CRL_FOUND] no certificate or crl
found (_ssl.c:4166)

In d:l:p alone, 1207 of 2310 packages have build failures
That means 53% of the packages no longer build!
But nobody seems to be interested.

The person who updated the package which now causes these errors should
please undo the update of the package. Or fix the error.

I have now send an request for python-pip to d:l:p with:

- To fix other package build errors, ca-certificates-mozilla must
  set from Recommends to Requires.

Not a good "fix": https://build.opensuse.org/request/show/1193880#comment-1973769 It pollutes every installation of pip on every OS with ca-certificates-mozilla. The motivation to fix 15.6 obs builds does not legitimate requiring installing unneeded packages for Tumbleweed and Slowroll users. The question you have to ask when attempting to fix the builds: Why does pip want to validate an SSL certificate during build? The obs machines are offline. - Ben
