Expected results:

package should install

Additional info:

The particular dependency is 

    Processing Dependency: qt5-qtbase(x86-64) = 5.9.2 for package: python36-qt5-base-5.12.1-2.el7.x86_64


which I can't see in the .spec file so I guess this is some magic auto dependency.

If tried to mock build qt5-qtbase pkg I end up with


 Problem: package qt5-qtwebkit-devel-5.9.1-2.el7.x86_64 requires libQt5WebKit.so.5()(64bit), but none of the providers can be installed
  - package qt5-qtwebkit-devel-5.9.1-2.el7.x86_64 requires libQt5WebKitWidgets.so.5()(64bit), but none of the providers can be installed
  - package qt5-qtwebkit-devel-5.9.1-2.el7.x86_64 requires qt5-qtwebkit(x86-64) = 5.9.1-2.el7, but none of the providers can be installed
  - conflicting requests


so I there may be a chain of these to build.


This looks very similar to
