Description of problem: notify-python-1.1.1-23.el7 is part of core os - epel7 shouldn't provide newer version. If epel7 version is needed it should have release number < 1.
What repo is it in? I can't find it in centos 7 or scientific linux 7.
https://git.centos.org/summary/rpms!notify-python
I asked centos folks why package is missing from distro.
According to bug #1044650 it was dropped from RHEL7
Ok. This is acutally problem with published git.centos.org repos with dropped packages - those repos are not properly closed. I filed a centos bug about the issue and they will hopefully close these repos.
