Foreman » Installer

Install foreman 1.12.3 all in one by foreman-installer, install ok and access web interface ok. The smart-proxy is added automatically, but the provisioning setup pre-requisites is not satisfied. the error show me is as showing in attached piture. There is no more information for to resole it and not found any steps to fix it in docs. Could any one give me some suggestion?

1. yum install vim wget unzip deltarpm epel-release -y
2. rpm -Uvh https://yum.puppetlabs.com/puppetlabs-release-pc1-el-7.noarch.rpm
