Error: ruby(selinux) is needed by puppet

While installing the puppet rpm’s we ran into an error. Note, we downloaded some prerequisite rpm’s first then attempted to install them.


[root@centos01 software]# ls -1
facter-2.4.1-1.el7.x86_64.rpm
hiera-1.3.4-1.el7.noarch.rpm
puppet-3.7.4-1.el7.noarch.rpm
puppet-server-3.7.4-1.el7.noarch.rpm
ruby-augeas-0.4.1-3.el7.x86_64.rpm
ruby-shadow-2.2.0-2.el7.x86_64.rpm



[root@centos01 software]# rpm -ivh *.rpm
warning: facter-2.4.1-1.el7.x86_64.rpm: Header V4 RSA/SHA512 Signature, key ID 4bd6ec30: NOKEY
error: Failed dependencies:

It would seem that selinux is causing some issue here. In this case we are missing a dependency. You will need to install the selinux ruby library. It can be done as follows


[root@centos01 software]# yum install libselinux-ruby
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile

Now that the library is installed we can now perform the installation of the puppet rpm’s
