Foreman » Installer

1) Install Foreman on CentOS 8
2) Upgrade host to Centos Stream 8, OS upgraded fine
3) Notice httpd did not start:

4) Attempt to run foreman-installer to resolve:

2020-12-14 11:16:14 [DEBUG ] [configure] importing '/usr/share/foreman-installer/modules/postgresql/manifests/globals.pp' in environment production
2020-12-14 11:16:14 [DEBUG ] [configure] Automatically imported postgresql::globals from postgresql/globals into production

2020-12-14 11:16:14 [NOTICE] [post] Executing hooks in group post

Looks like the OS detection code in /usr/share/foreman-installer/modules/postgresql/manifests/globals.pp does not know how to resolve CentOS 8 version strings and may need an update
