Description of problem:

https://issues.redhat.com/browse/SAT-24811 This was the reported issue for which we added a check in satellite-maintain but the same issue can fail a new installation as well in ipv6 disabled environment.

How reproducible:

Every Time

Steps to Reproduce:

1. Disable "ipv6.disable=1 " from kernel options in the file /boot/grub2/grubenv

2. check ipv6 loopback port is not listening 

1. netstat -antup | grep "\::1"

3. enable repos and install satellite 6.15.

1. subscription-manager repos --disable "*"

1. subscription-manager repos --enable=rhel-8-for-x86_64-baseos-rpms \
   --enable=rhel-8-for-x86_64-appstream-rpms \
   --enable=satellite-6.15-for-rhel-8-x86_64-rpms \
   --enable=satellite-maintenance-6.15-for-rhel-8-x86_64-rpms

1. dnf module enable satellite:el8

1. dnf install satellite

1. satellite-installer --scenario satellite \
   --foreman-initial-organization "My_Organization" \
   --foreman-initial-location "My_Location" \
   --foreman-initial-admin-username admin_user_name \
   --foreman-initial-admin-password admin_password

Actual behavior:
The error from /var/log/foreman-installer/satellite.log

Expected behavior:
during installation health check should fail with the same ipv6.disable=1 warning/error

and return msg to use the correct article to fix the ipv6. https://access.redhat.com/solutions/5045841
