Converting legacy compilers fails with an external certificate authority

If you use an external certificate authority (CA), the puppet infrastructure run convert_legacy_compiler command fails with an error during the certificate-signing step.
Agent_cert_regen: ERROR: Failed to regenerate agent certificate on node <>
Agent_cert_regen: bolt/run-failure:Plan aborted: run_task 'enterprise_tasks::sign' failed on 1 target
Agent_cert_regen: puppetlabs.sign/sign-cert-failed Could not sign request for host with certname <> using caserver <>
To work around this issue when it appears:
  1. Log on to the CA server and manually sign certificates for the compiler.
  2. On the compiler, run Puppet: puppet agent -t
  3. Unpin the compiler from PE Master group, either from the console, or from the CLI using the command: /opt/puppetlabs/bin/puppet resource pe_node_group "PE Master" unpinned="<COMPILER_FQDN>"
  4. On your primary server, in the pe.conf file, remove the entry puppet_enterprise::profile::database::private_temp_puppetdb_host
  5. If you have an external PE-PostgreSQL node, run Puppet on that node: puppet agent -t
  6. Run Puppet on your primary server: puppet agent -t
  7. Run Puppet on all compilers: puppet agent -t

Converted compilers can slow PuppetDB in multi-region installations

In configurations that rely on high-latency connections between your primary servers and compilers – for example, in multi-region installations – converted compilers running the PuppetDB service might experience significant slowdowns. If your primary server and compilers are distributed among multiple data centers connected by high-latency links or congested network segments, reach out to Support for guidance before converting legacy compilers.

Disaster recovery known issues

These are the known issues for disaster recovery in this release.

There are no known issues related to disaster recovery at this time.

FIPS known issues

These are the known issues with FIPS-enabled PE in this release.

Puppet agent fails to start on FIPS-compliant RHEL 7 and 8

After you install or upgrade the Puppet agent on FIPS-compliant Red Hat Enterprise Linux (RHEL) 7 or 8, you might find that the puppet service stops. Running journalctl --unit puppet might return an error message similar to the following:
Sep 22 17:53:49 <hostname> puppet[8982]: Error: Could not run: SSL_CTX_new: library has no ciphers

Until the issue is fixed, you can manually start the puppet service by running systemctl start puppet on the agent node.

FIPS-enabled PE 2023.0 and later can't use the default system cert store

FIPS-compliant builds running PE 2023.0 and later can't use the default system cert store, which is used automatically with some reporting services. This setting is configured by the report_include_system_store Puppet parameter that ships with PE.

Removing the puppet-cacerts file (located at /opt/puppetlabs/puppet/ssl/puppet-cacerts) can allow a report processor that eagerly loads the system store to continue with a warning that the file is missing.

If HTTP clients require external certs, we recommend using a custom cert store containing only the necessary certs. You can create this cert store by concatenating existing pem files and configuring the ssl_trust_store Puppet parameter to point to the new cert store.

Puppet Server FIPS installations don’t support Ruby’s OpenSSL module

FIPS-enabled PE installations don't support extensions or modules that use the standard Ruby Open SSL library, such as hiera-eyaml. As a workaround, you can use a non-FIPS-enabled primary server with FIPS-enabled agents, which limits the issue to situations where only the primary uses the Ruby library. This limitation does not apply to versions 1.1.0 and later of the splunk_hec module, which supports FIPS-enabled servers. The FIPS Mode section of the module's Forge page explains the limitations of running this module in a FIPS environment.

Configuration and maintenance known issues

These are the known issues for configuration and maintenance in this release.

Puppet Server memory leak due to issue in concurrent-ruby

Puppet Server can leak memory due to a known issue in the concurrent-ruby version packaged with Puppet Server in PE 2023.4 and later. This issue results in gradual degradation of Puppet Server performance until the service crashes or is restarted.

To avoid problems associated with memory leaks until the issue is resolved, you can manually update the concurrent-ruby gem by running the following command on each infrastructure node that hosts Puppet Server:
puppetserver gem install --no-document -v 1.2.2 concurrent-ruby

Restoring PE from a backup might fail when puppet agent is running

When you run puppet-backup restore and a Puppet run is either already in progress or starts during the restore process, the restore operation might fail with an error. Until this issue is fixed, you can use the following workaround to avoid the error:

Before initiating the restore operation, run the following command to prevent Puppet runs:

puppet agent --disable
When the restore operation is complete, run the following command to allow Puppet runs again:
puppet agent --enable

Puppet autorequire functionality fails when an exec resource command is deferred

Puppet enables resources to automatically require other resources, so you do not have to explicitly state an order of dependencies. For example, if you're managing an exec resource that runs a file, Puppet automatically ensures that the file is created or managed before executing the exec.

However, currently when the exec resource's command is deferred, the exec resource fails with an error similar to:
Error: Failed to apply catalog: undefined method `scan' for #<Puppet::Pops::Evaluator::DeferredValue

Until the issue is resolved, you can set the preprocess_deferred parameter as true, either in the in the main section of the agent puppet.conf file, or in the puppet_enterprise::profile::agent class in the console. This setting forces the agent to evaluate all deferred parameters immediately when the catalog is applied, rather than lazily as each resource is evaluated.

puppet infrastructure tune fails with multi-environment environmentpath

The puppet infrastructure tune command fails if environmentpath (in your puppet.conf file) is set to multiple environments. To avoid the failure, comment out this setting before running this command. For details about the environmentpath setting, refer to environmentpath in the open source Puppet documentation.

Restarting or running Puppet on infrastructure nodes can trigger an illegal reflective access operation warning

When restarting PE services or performing agent runs on infrastructure nodes, you might see this warning in the command-line output or logs: Illegal reflective access operation ... All illegal access operations will be denied in a future release

These warnings are internal to PE service components and have no impact on their functionality. You can safely disregard them.

Orchestration services known issues

Console and console services known issues

No issues are known for the console and console services at this time.

Patching known issues

These are the known issues for patching in this release.

Patching fails with excluded YUM packages

In the patching task or plan, using yum_params to pass the --exclude flag in order to exclude certain packages can result in task or plan failure if the only packages requiring updates are excluded. As a workaround, use the versionlock command (which requires installing the yum-plugin-versionlock package) to lock the packages you want to exclude at their current version. Alternatively, you can fix a package at a particular version by specifying the version with a package resource for a manifest that applies to the nodes to be patched.

Code management known issues

These are the known issues for Code Manager, r10k, and file sync in this release.

Changing a file type in a control repo produces a checkout conflict error

Changing a file type in a control repository – for example, deleting a file and replacing it with a directory of the same name – generates the error JGitInternalException: Checkout conflict with files accompanied by a stack trace in the Puppet Server log. As a workaround, deploy the control repo with the original file deleted, and then deploy again with the replacement file or directory.
