Hi all, From now on pytest4 is default on tumbleweed and some packages might start to fail due to the fact. Now we ship 3 variants of pytest: 1) python-pytest (5.0) python3 only 2) python-pytest4 (4.x series) py3 and py2 supported (This is now primary selected pytest by TW) 3) python-pytest3 (3.x series) py3 and py2 supported used for pkgs that are stuck in old api. If your packages requires the old pytest just write in the old variant, ie.: BuildRequires: %{python_module pytest3} If your package got stuck on building with py3 suddenly it might mean the pytest5 got in TW and the package is not working with it and we should file a bug upstream. From the above I hope it is obvious pytest4 is with us for quite longer, yet I hope we will manage to push out pytest3 completely soonTM. Cheers Tom
