(SA) Support Tip: 10.50 prerequisite errors related to SELinux
During the installation you may encounter the following pre-req check failures:
FAILURE 'uid=0(root)' cannot create new users.
FAILURE SELinux is enabled and enforcing.
The second error is an easy to fix which is documented in the installation guide and can be found by searching on selinux). Once SELinux is disabled the second error disappears but the first remains. It turns out a reboot is required after the changes to disable SELinux are made in the SELINUX config file, after a reboot the “cannot create new users” message was resolved.
