We did not find at least one configured Smart Proxy with the Puppet feature

I have installed puppetmaster, puppet and foreman in Ubuntu 12.04, puppetmaster and agent is configured to report to foreman and its working fine.

I can see my host in foreman UI... Up to this everything is fine..............

Now the problem is,

I have installed ntp, nexus and other modules in /etc/puppet/modules directory but none of these modules/classes are showing up in foreman ui ( Classes ) section.

My Configuration

puppet agent  3.0.1
foreman       1.11
puppet master 3.0.1
ruby          1.9.3

In master section of puppet.conf, I have

[production] environment path set to /etc/puppet/modules

Tried restarting puppetmaster and foreman, but not working

Then, I tried this,

admin@host:/usr/share/foreman$ sudo foreman-rake db:migrate --trace
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:migrate

admin@host:/usr/share/foreman$ sudo foreman-rake puppet:import:puppet_classes --trace
** Invoke puppet:import:puppet_classes (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute puppet:import:puppet_classes

I am getting the below error

ERROR: We did not find at least one configured Smart Proxy with the Puppet feature

Btw, I have the proxy configured and running fine and I have log service running in it. I didn't have SSL enabled, but http port is running and listening...

UPDATE 1:

Now I enabled puppet.yml along with SSL options under /etc/foreman-proxy/settings.d/settings.yml. I then navigated to proxy section in foreman GUI and found this log

Message

I tried to install ruby-augeas gem, but got this error,

Solution

Well, there's a whole bunch of issues here.

Foreman 1.11 is not the current version, please use Foreman 1.12. It supports the current version of Puppet (4.x) and more modern Ubuntu releases.
Puppet 3.0.x is a really bad release to use, because it has poor support in Foreman and had a number of issues. There's no reason not to be using Puppet 3.8.x or preferably 4.x with Foreman 1.12.
Ubuntu 12.04 is a very old release to be installing new software onto, use 16.04 or 14.04. Foreman 1.11 had deprecated its support for Ubuntu 12.04, so I wouldn't recommend putting a new installation onto it.
If missing the Augeas dependency, install the package, don't try installing gems over the top - you'll probably introduce new issues. apt-get install libruby-augeas1.8
