Output snippet from puppet run when using the foreman/foreman module from GitHub:

Error: Execution of '/usr/bin/yum -d 0 -e 0 -y install foreman-release-scl' returned 1: Package rhscl-ruby193-epel-7-x86_64-1-2.noarch.rpm is not signed
Error: /Stage[main]/Foreman::Install::Repos::Extra/Package[foreman-release-scl]/ensure: change from absent to present failed: Execution of '/usr/bin/yum -d 0 -e 0 -y install foreman-release-scl' returned 1: Package rhscl-ruby193-epel-7-x86_64-1-2.noarch.rpm is not signed

If I change the yumrepo::gpgcheck setting from 1 to 0 for the 'foreman' repo, then installation works. Or if I manually run "yum --nogpgcheck install foreman-release-scl", then I can run puppet and leave the gpgcheck enabled for the other RPMs in the repository.
