Installation and upgrade known issues

After upgrade, agent runs trigger a cyclical dependency

Error: Found 1 dependency cycle:
(File[/etc/yum.repos.d/pc_repo.repo] => Class[Puppet_enterprise::Repo::Config] => Stage[pe_setup] => Stage[main] => Class[Main] => Node[default] => File[/etc/yum.repos.d] => File[/etc/yum.repos.d/pc_repo.repo])\nCycle graph written to /opt/puppetlabs/puppet/cache/state/graphs/cycles.dot.
Error: Failed to apply catalog: One or more resource dependency cycles detected in graph

Java 1.8.181 can cause directory services to fail in upgrade

Because of changes to LDAP support in Java 8 Update 181, Puppet Enterprise might be unable to connect to external directory services (DS) when you upgrade to PE 2018.1.3 or later. This occurs when the hostname PE uses to communicate with the directory service does not match the CN or one DNS altname of the certificate presented by the directory service.

As a workaround, disable the stricter endpoint verification that is the default in Java.

Web-based installation requires a second Puppet run to fully install PE services

Web-based installation includes a single, intitial Puppet run, but a second Puppet run is required in order to populate services.conf. Until a second Puppet run completes, the Puppet service status in the console reports that one or more services isn't accepting requests.

Ubuntu 16.10 agents can't be installed with package management

Installation using package management isn't currently supported. If you need to install an Ubuntu 16.10 agent, log into the node where you want to install the agent and run:

wget https://apt.puppetlabs.com/puppetlabs-release-pc1-yakkety.deb
sudo dpkg -i puppetlabs-release-pc1-yakkety.deb

Incorrect credentials for console databases cause split upgrade to fail

During a split upgrade, if you supply incorrect credentials for the database associated with the console, including database names, user names, or passwords, the upgrade process fails with an error message. Verify that you're using the correct database credentials and re-run the upgrader. The credentials can be found on the PuppetDB node at /etc/puppetlabs/installer/database_info.install.

Web-based installer fails to acknowledge failed installs due to low RAM

When installation fails because a system is not provisioned with adequate RAM, the web-based installer stops responding, but the Start using Puppet Enterprise button is available, suggesting that installation succeeded. In these cases, the command line shows an out of memory: Kill process error.

Provision the system with adequate RAM and re-run the installation.

Hard tabs for indentation in Hiera YAML files cause errors after upgrading

Before upgrade, ensure that any Hiera YAML files do not use hard tabs for indentation.

Incorrect umask value can cause installation and upgrade to fail

Set an umask value of 0022 on your master.

Upgrade fails if autosign.conf contains invalid entries

Entries in /etc/puppetlabs/puppet/autosign.conf that don't conform to autosign requirements cause the upgrade to fail when configuring the console. Correct any invalid entries before upgrading.

Install agents with different OS when master is behind a proxy

If your master uses a proxy server to access the internet, you might not be able to download pe_repo packages for the agent.

If you're using a proxy, follow this workaround:

1. From your master, navigate to /etc/sysconfig/, and create a file called puppet with this code: 

   export http_proxy <YOUR_PROXY_SERVER>
      export https_proxy <YOUR_PROXY_SERVER>

2. Save and close the file, and then restart the puppet service:

   puppet resource service puppet ensure=stopped
      puppet resource service puppet ensure=running

3. Repeat these steps on any compile masters in your environment.
