Foreman 2.0 with CentOS 7U7 installation issues

Problem:
I am trying to install Foreman 2.0 and following steps mentioned in the foreman installation notes specific to CentOS 7 however it fails with below error. Any idea what is going on here and how can I fix it?

# foreman-installer
Running Start Services
================================================================================
Check if command is run as root user:                                 [OK]
--------------------------------------------------------------------------------
Start applicable services: 
Starting the following service(s):
postgresql
| All services started                                                [OK]      
--------------------------------------------------------------------------------

foreman-maintain service start --only=postgresql finished successfully!
could not change directory to "/root"
Running Stop Services
================================================================================
Check if command is run as root user:                                 [OK]
--------------------------------------------------------------------------------
Stop applicable services: 
Stopping the following service(s):                                    [FAIL]
No services found matching your parameters
--------------------------------------------------------------------------------
Scenario [Stop Services] failed.

The following steps ended up in failing state:

  [service-stop]

Resolve the failed steps and rerun
the command. In case the failures are false positives,
use --whitelist="service-stop"


foreman-maintain service stop failed! Check the output for error!

Expected outcome:
Foreman 2.0 should be able to install on Cent 7.

Foreman and Proxy versions:
Foreman master only version 2.0

Foreman and Proxy plugin versions:

Distribution and version:
CenOS 7U7 + Foreman 2.0

What is CentOS 7U7?

Installer logs should be in /var/log/foreman-installer

Maybe they mean CentOS 7.7? 7.8 just came out so it’s plausible.
