Different Linux distributives have different pack names. I tested in Centos and Ubuntu. These certificate bundles are updates with system update. So you may just detect which bundle is available and use it with urlopen.

cafile = None
for i in [
    '/etc/ssl/certs/ca-bundle.crt',
    '/etc/ssl/certs/ca-certificates.crt',
]:
    if os.path.exists(i):
        cafile = i
        break
if cafile is None:
    raise RuntimeError('System CA-certificates bundle not found')
