Compiler upgrade fails with no-op configured

Upgrade fails on compilers running in no-op mode. As a workaround, remove the no-op setting on compilers before upgrading.

Compiler upgrade fails with client certnames defined

Existing settings for client certnames can cause upgrade to fail on compilers, typically with the error Value does not match schema: {:client-certnames disallowed-key}. As a workaround, manually remove any client-certnames settings for compilers from /etc/puppetlabs/puppetserver/conf.d/file-sync.conf.

Windows agent installation fails with a manually transferred certificate

Performing a secure installation on Windows nodes by manually transferring the primary server CA certificate fails with the connection error: Could not establish trust relationship for the SSL/TLS secure channel.

Initial agent run after upgrade can fail with many environments

In installations with many environments, where file sync can take several minutes, the orchestration service fails to reload during the first post-upgrade Puppet run. As a workaround, re-run the Puppet agent until the orchestration service loads properly. To prevent encountering this error, you can clean up unused environments before upgrading, and wait several minutes after the installer completes to run the agent.

Installing Windows agents with the .msi package fails with a non-default INSTALLDIR

When installing Windows agents with the .msi package, if you specify a non-default installation directory, agent files are nonetheless installed at the default location, and the installation command fails when attempting to locate files in the specified INSTALLDIR.

Upgrade fails with cryptic errors if agent_versions are configured for your infrastructure pe_repo class

If you've configured the agent_version parameter for the pe_repo class that matches your infrastructure nodes, upgrade can fail with a timeout error when the installer attempts to download a non-default agent version. As a workaround, before upgrading, remove from the console (in the PE Master node group), Hiera, or pe.conf any agent_version parameters for the pe_repo class that matches your infrastructure nodes.

Converting legacy compilers fails with an external certificate authority

Agent_cert_regen: ERROR: Failed to regenerate agent certificate on node <compiler-node.domain.com>
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 <compiler-node.domain.com> using caserver <master-host.domain.com>

Converted compilers can slow PuppetDB in geo-diverse installations

In configurations that rely on high-latency connections between your primary servers and compilers – for example, in geo-diverse 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.

Upgrading to newer version with versioned deploys causes Puppet Server to crash

If versioned_deploys is enabled when upgrading to version 2019.8.6 or 2021.1, then the Puppet Server crashes.

Puppet runs can take longer than expected in failover scenarios

In disaster recovery environments with a provisioned replica, if the primary server is unreachable, a Puppet run using data from the replica can take up to three times as long as expected (for example, 6 minutes versus 2 minutes).

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 or the splunk_hec module. 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 agent uses the Ruby library.

Errors when using puppet code and puppet db commands on FIPS-compliant platforms

/opt/puppetlabs/puppet/bin/gem install puppetdb_cli --bindir /opt/puppetlabs/bin/

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 the warning Illegal reflective access operation ... All illegal access operations will be denied in a future release in the command-line output or logs. These warnings are internal to PE service components, have no impact on their functionality, and can be safely disregarded.

Backup fails with an error about the stockpile directory

The puppet-backup create command fails under certain conditions with an error that the /opt/puppetlabs/server/data/puppetdb/stockpile directory is inaccessible.

Running plans during code deployment can result in failures

If a plan is running during a code deployment, things like compiling apply block statements or downloading and running tasks that are part of a plan might fail. This is because plans run on a combination of PE services, like orchestrator and puppetserver, and the code each service is acting on might get temporarily out of sync during a code deployment.

Pantomime dependency in the orchestrator

The version of pantomime in the orchestrator had a third party vulnerability (tika-core). Because of the vulnerability, pantomime usage was removed from the orchestrator, but pantomime still exists in the orchestration-services build.

Console reboot task fails

Rebooting a node using the reboot task in the console fails due to the removal of win32 gems in Puppet 7. As a workaround, update the reboot module to version 4.0.2 or later.

Gateway timeout errors in the console

Using facts to filter nodes might produce either a "502 Bad Gateway" or "Gateway Timeout" error instead of the expected results.

Injection attack vulnerability in csv exports

There's a vulnerability in the console where .csv files could contain malicious user input when exported.

Patching fails on Windows nodes when run during a fact generation

Add-LogEntry : Exception caught: Lock file found, it appears PID is another copy of pe_patch_fact_generation or pe_patch_groups

Patching fails on Windows nodes with non-default agent location

On Windows nodes, if the Puppet agent is installed to a location other than the default C: drive, the patching task or plan fails with the error No such file or directory.

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.

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.

Enabling Code Manager and multithreading in Puppet Server deadlocks JRuby

Setting the new environment_timeout parameter to any non-zero value – including the unlimited default when Code Manager is enabled – interferes with multithreading in Puppet Server and can result in JRuby deadlocking after several hours.

Default SSH URL with TFS fails with Rugged error

Using the default SSH URL with Microsoft Team Foundation Server (TFS) with the rugged provider causes an error of "unable to determine current branches for Git source." This is because the rugged provider expects an @ symbol in the URL format.

To work around this error, replace ssh:// in the default URL with git@

ssh://tfs.puppet.com:22/tfs/DefaultCollection/Puppet/_git/control-repo

git@tfs.puppet.com:22/tfs/DefaultCollection/Puppet/_git/control-repo

GitHub security updates might cause errors with shellgit

GitHub has disabled TLSv1, TLSv1.1 and some SSH cipher suites, which can cause automation using older crypto libraries to start failing. If you are using Code Manager or r10k with the shellgit provider enabled, you might see negotiation errors on some platforms when fetching modules from the Forge. To resolve these errors, switch your configuration to use the rugged provider, or fix shellgit by updating your OS package.

Timeouts when using --wait with large deployments or geographically dispersed compilers

Because the --wait flag deploys code to all compilers before returning results, some deployments with a large node count or compilers spread across a large geographic area might experience a timeout. Work around this issue by adjusting the timeouts_sync parameter.

r10k with the Rugged provider can develop a bloated cache

If you use the rugged provider for r10k, repository pruning is not supported. As a result, if you use many short-lived branches, over time the local r10k cache can become bloated and take up significant disk space.

If you encounter this issue, run git-gc periodically on any cached repo that is using a large amount of disk space in the cachedir. Alternately, use the shellgit provider, which automatically garbage collects the repos according to the normal Git CLI rules.

Code Manager and r10k do not identify the default branch for module repositories

When you use Code Manager or r10k to deploy modules from a Git source, the default branch of the source repository is always assumed to be main. If the module repository uses a default branch that is not main, an error occurs. To work around this issue, specify the default branch with the ref: key in your Puppetfile.

After an error during the initial run of file sync, Puppet Server won't start

The first time you run Code Manager and file sync on a primary server, an error can occur that prevents Puppet Server from starting. To work around this issue:

1. Stop the pe-puppetserver service.
2. Locate the data-dir variable in /etc/puppetlabs/puppetserver/conf.d/file-sync.conf.
3. Remove the directory.
4. Start the pe-puppetserver service.

Repeat these steps on each primary server exhibiting the same symptoms, including any compilers.

Puppet Server crashes if file sync can't write to the live code directory

If the live code directory contains content that file sync didn’t expect to find there (for example, someone has made changes directly to the live code directory), Puppet Server crashes.

The following error appears in puppetserver.log:

2016-05-05 11:57:06,042 ERROR [clojure-agent-send-off-pool-0] [p.e.s.f.file-sync-client-core] Fatal error during file sync, requesting shutdown.
org.eclipse.jgit.api.errors.JGitInternalException: Could not delete file /etc/puppetlabs/code/environments/development
        at org.eclipse.jgit.api.CleanCommand.call(CleanCommand.java:138) ~[puppet-server-release.jar:na]

To recover from this error:

1. Delete the environments in code dir: find /etc/puppetlabs/code -mindepth 1 -delete
2. Start the pe-puppetserver service: puppet resource service pe-puppetserver ensure=running
3. Trigger a Code Manager run by your usual method.

Code Manager can't recover from Puppetfile typos in URL

When you have a git typo in your Puppetfile, subsequent code deploys continuously fail until you manually delete deployer caches, even after the Puppetfile error is corrected.

File sync fails to copy symlinks if versioned deploys is enabled

If you enable versioned deploys, then the file sync fails to copy symlinks and incorrectly copies the symlinks' targets instead. This copy failure crashes the Puppet Server.
