Problem: Could not evaluate: Exception SSL_connect returned=1 errno=0 state=error: certificate verify failed (self signed certificate in certificate chain)

Expected outcome: Foreman installer should use custom certificate

Can someone from Foreman suggest on this

Having the same issue myself with a fresh install Foreman 3.1 and Katello 4.3.

Heck I am even getting this issue with self signed certs.

It was not the best solution, however I managed to get the installer working after manually modifying a script file.

Under Foreman 3.1, Katello 4.3 and a custom Foreman server certificate signed by a local FreeIPA deployment, I was experiencing the below exception details, recorded in /var/log/foreman-installer/katello.log file:

2022-01-08 14:49:47 [DEBUG ] [configure] /Stage[main]/Foreman::Register/Foreman_host[foreman-foreman.corp.andersongomes.tech]: Starting to evaluate the resource (1795 of 1916)

After inspecting the /usr/share/foreman-installer/modules/foreman/lib/puppet/provider/foreman_resource/rest_v3.rb file and noticing via introduced debugging messages that the oAuth call was being validated against the CA bundle located in /etc/pki/katello/certs/katello-default-ca.crt file, I manually modified the line #50 and explicitly referenced the /etc/pki/katello/certs/katello-server-ca.crt file, instead.

  def oauth_consumer
    @consumer ||= OAuth::Consumer.new(oauth_consumer_key, oauth_consumer_secret, {
      :site               => resource[:base_url],
      :request_token_path => '',
      :authorize_path     => '',
      :access_token_path  => '',
      :timeout            => resource[:timeout],
      :ca_file            => '/etc/pki/katello/certs/katello-server-ca.crt'
    })
  end

I don’t know the consequences introduced by the change, though. I am just trying to get Foreman working in my lab environment.

Modifying this line fixed it for me as well. Going to report this as a bug.
