error message when I tried to run puppet and apply changes to the system

[Chris Zou]

I am new to Puppet, and I am trying to follow Quest Learning Machine from Puppet Lab.

 

However, every time I tried to run 

puppet apply cowsayings/tests/cowsay.pp

 

Error message comes up like this:

 

Warning: The package type's allow_virtual parameter will be changing its default value from false to true in a future release. If you do not want to allow virtual packages, please explicitly set allow_virtual to false.

What does "Cannot find a valid baseurl for repo: epel" mean? How can I fix these errors?

 

I really appreciate your help!!

That's a warning, not an error, and it is moreover not directly related to your issue.

 

Error: Execution of '/usr/bin/yum -d 0 -e 0 -y list cowsay' returned 1: Error: Cannot find a valid baseurl for repo: epel

That's an error originally encountered by yum, as launched by Puppet to check the latest available version of package 'cowsay'.  "Network is unreachable" seems to speak for itself.  It is not a Puppet issue, though possibly is signals broken network configuration.

This one is just a followon from the previous one.

The error message is emitted by yum; Puppet is only the messenger.  Nevertheless, the root problem is described in the next lines: "error was [...] Network is unreachable".

It appears that your machine has a physical network connection because it was able to resolve the machine name in the mirrorlist URL to an address.  If it cannot then find a route to that address, as the error message seems to indicate, then that probably means your network configuration requires you to send traffic through a proxy server.  In that case, you should configure yum appropriately to use your network's proxy server via the "proxy" property and maybe the "proxy_user" and "proxy_password" properties in /etc/yum.conf.
