First Time Installing Puppet

[Net Warrior]

Hi there guys
Need some help, this is my first time installing puppet , this is my conf:

Installed the repo https://docs.puppet.com/puppet/3.8/install_el.html
rpm -ivh https://yum.puppetlabs.com/puppetlabs-release-el-7.noarch.rpm

RHEL 7 x64
3.10.0-327.13.1.el7.x86_64 #1 SMP Mon Feb 29 13:22:02 EST 2016 x86_64

You could try using --skip-broken to work around the problem

Hello,
There appears to be something really odd going on with that system.

You should see if you can replicate those errors in a clean minimal RHEL7 VM.

I was not able to duplicate it in a clean RHEL7.3 VM installed with the package groups @core and @base. Then I installed the release rpm just like you did, then did yum install puppetserver and it worked perfectly. See https://paste.fedoraproject.org/paste/5EUNcqsa8WiCtzILiLbQIl5M1UNdIGYhyRLivL9gydE=

On your system it looks you have installed Ruby 2.2 installed which is not the ruby that comes with base RHEL7.

I am guessing based on the names rh-ruby22-runtime and rh-ruby22-ruby that they came from are Ruby 2.2 via Software Collections. So this time I reloaded the clean VM, installed ruby 2.2 from SCL, then installed the puppet release rpm, then yum installed puppetserver, and it too worked perfectly. See https://paste.fedoraproject.org/paste/32tFWQM7iueye~hVjDyxQl5M1UNdIGYhyRLivL9gydE=

So I read your error output as Yum is having a collision on ruby dependencies, and if so then I guess that on that machine someone has installed ruby 2.2 (  https://www.softwarecollections.org/en/scls/rhscl/rh-ruby22/  )as the 'system ruby', where if the directions from Red Hat are followed on Software Collections, then it will not collide and overwrite the normal 'system ruby' ruby 2.0.0.

[root@localhost ~]# scl enable rh-ruby22 bash
[root@localhost ~]# which ruby
/opt/rh/rh-ruby22/root/usr/bin/ruby
[root@localhost ~]# ruby --version
ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-linux]
[root@localhost ~]# exit
exit
[root@localhost ~]# which ruby
/bin/ruby
[root@localhost ~]# ruby --version
ruby 2.0.0p648 (2015-12-16) [x86_64-linux]
[root@localhost ~]#

You might want to identify where all those ruby RPMs came from:
# for i in $(rpm -qa | grep -i ruby) ; do echo $i ; yum info $i ; echo "-------------------" ; done

Regards,

James

Puppet 3.8 is deprecated. You should not install this version.

Instructions to install latest version can found at:

https://docs.puppet.com/puppet/4.9/install_linux.html
