Hello,
I want to install TheForeman beside our Puppet Enterprise Server for provisioning's aspect.
So I installed TheForeman without Puppet on a new server and also installed foreman smart-proxy
from rpm on our Puppet Enterprise server and configured Puppet and Puppetca smart-proxy.
But something is going wrong because I've this following error when I start foreman-proxy service :
