[opensuse-packaging] OBS: Temporary failure in name resolutio

HI! For all Factory and Tumbleweed repos I get build failures with this message: [ 34s] Download error on https://pypi.python.org/simple/: [Errno -3] Temporary failure in name resolution -- Some packages may not be found! Re-triggering the build several times within a longer timespan did not help. It works for SLES and Leap build targets. Any clue what's wrong there? Ciao, Michael.
