Problem scenario: You want to troubleshoot a variety of issues with Puppet. You go to Puppet’s page for “Troubleshooting Common Errors.” It says that a “A newer version is available; see the version menu above for details.”

Problem scenario
Your newly installed Puppet Master is not working. The main service will not start. You try this command: service puppetserver restart
You see this as the results of the above command:
“Job for puppetserver.service failed because the control process exited with error code. See “systemctl status puppetserver.service” and “journalctl -xe” for details.”

systemctl status puppetserver.service
It results in this:

Problem scenario: On a Linux server you run “puppet agent -t” to apply a manifest on a Puppet Agent. You receive this error:
“Error: Could not retrieve local facts: undefined method ‘require_relative’ for main:Object”
What do you do to fix this?
Solution: Install a compatible version of Puppet agent on the server. One way to do this is to run this command:
curl -k https://continualintegration:8140/packages/current/install.bash | sudo bash`
#where “continualintegration” is the hostname (or FQDN) of the Puppet Master server.

Problem scenario: Some manifests kick off a non-Puppet script that has a long duration. By default the manifest will time out after 300 seconds. That means the manifest will not run properly if it cannot complete in five minutes. How do you run long-duration manifests?
Solution (Part 1 of 2): Use the timeout => directive. For example in the Puppet manifest, have a stanza like this:

Problem Scenario: You are using Puppet Master on Linux and Puppet Agent on Windows servers. The manifest attempts to copy to or from a Windows network file share, but you are getting an error about the network path not existing. The network file share has permissions that are open to Everyone. What do you do?
Solution: Puppet Agent will run PowerShell commands under the security context of the user who runs the “puppet agent -t -d” command.

Problem scenario: One Puppet manifest relies on another manifest to work. Trying to apply them at the same time is not working. The “require” and “before” keywords only seem to work for packages, exec, and file resources. What do you do to order the manifests to satisfy dependency requirements of other manifests?
Solution: The relationship dependency can be solved by the order in which they are applied.
