Description of problem:

# for i in obsoletes provides ; do rpm -q --${i} udisks2; echo ; done
storaged

udisks2 = 2.7.3-4.el7
udisks2(x86-64) = 2.7.3-4.el7


Originally found when trying install EL 7.5 as RHV 4.2 host:

--->%---
I was trying to install rhv 4.2 on EL 7.5 but it fails:

- cockpit-storaged-155-1.el7.noarch.rpm

  depends on storaged but this package got obsoleted by
  udisks2 and thus version comparison does not match

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest


# rpm -qRp cockpit-storaged-155-1.el7.noarch.rpm  | grep ^storaged
storaged >= 2.1.1
storaged-iscsi >= 2.1.1
storaged-lvm2 >= 2.1.1

# rpm -q --provides --obsoletes udisks2
udisks2 = 2.7.3-4.el7
udisks2(x86-64) = 2.7.3-4.el7
storaged

My current workaround: install all deps via yum and install cockpit-storaged via rpm
with --nodeps.

Version-Release number of selected component (if applicable):
udisks2-2.7.3-4.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1. install EL 7.5 and try to install ovirt-host package from RHV 4.2(beta)
2.
3.

Actual results:
installation ovirt-host as its dependency cockpit-storaged needs specific storaged package which is obsoletes with udisks2 but udisks2 does not provide 'storaged >= 2.1.1'

Expected results:
udisks2 should has 'provides' for storaged >= 2.1.1
