Bug 2024360

Description of problem: 

We have a customer seeing this on rhvh-4.4.4.1-0.20210201.0 during their attempt to install sssd-proxy, but reproduced with rhvh-4.4.8.1-0.20210903.0+1 in the lab: 

rhvh-4.4.8.1-0.20210903.0+1 installs the following version of sssd-common: 

[root@shaggy ~]# rpm -qa | grep sssd-common
sssd-common-2.4.0-9.el8_4.2.x86_64
sssd-common-pac-2.4.0-9.el8_4.2.x86_64


However the rhvh-4-for-rhel-8-x86_64-rpms repository contains newer versions.  Notably 2.5.2-2.el*: 

[root@shaggy ~]# yum list --showduplicates | grep sssd-common
sssd-common.x86_64                                         2.4.0-9.el8_4.2                                             @System

Due to this, a yum install of sssd-proxy fails with the following:

[root@unused ~]# yum install sssd-proxy

Error: 
 Problem: package sssd-proxy-2.5.2-2.el8_5.1.x86_64 requires sssd-common = 2.5.2-2.el8_5.1, but none of the providers can be installed
  - cannot install the best candidate for the job
  - package sssd-common-2.5.2-2.el8_5.1.x86_64 is filtered out by exclude filtering

Now if we install sssd-proxy-2.4.0-9.el8_4.2.x86_64 we are right back in the same boat:
yum install sssd-proxy-2.4.0-9.el8_4.2.x86_64  (success)

At this point it's unclear what an upgrade of the system might do and if this would cause issue for the customer down the road. 




Version-Release number of selected component (if applicable):

rhvh-4.4.8.1-0.20210903.0+1
sssd-common-2.4.0-9.el8_4.2.x86_64
sssd-proxy-2.4.0-9.el8_4.2.x86_64

How reproducible:
Install rhvh and upgrade to the latest version available, then attempt yum install sssd-proxy 



Steps to Reproduce:
1. install rhvh
2. yum update to bring rhvh to the latest version
3. yum install sssd-proxy  (this will fail)
4. yum install sssd-proxy-2.4.0-9.el8_4.2.x86_64 (this will succeed)
5. yum update (this will error) 




Actual results:
[root@unused ~]# yum install sssd-proxy
Updating Subscription Management repositories.
Unable to read consumer identity

Expected results:

Successful install of the correct version and a clean 'yum update' run directly after.
