Troubleshooting

Bolt can't find my task

Run the bolt task show command or Get-BoltTask PowerShell cmdlet and look for any warnings related to your task metadata.

Make sure your task name is valid: Task names must

Be lowercase
Start with a letter
Can only contain letters, numbers and underscores

Make sure your task executable is named the same as your task metadata. For example, if your task is named mytask.rb, you must name your metadata file mytask.json.

I can't add a module to my Bolt project

If you receive the following error:

Unable to use command 'bolt module add'. To use this command, update your project configuration to manage module dependencies.

You need to upgrade your project so Bolt can manage your modules and dependencies. For more information, see migrate a Bolt project.

My task fails with a "permission denied" error (`noexec` issue)

If your task fails with the following error, the issue may be that your temporary directory (tmpdir) is mounted with noexec.

The task failed with exit code 126 and no stdout but stderr contained: 
.... <temp path to task>>.rb: Permission denied

You can resolve this by configuring an alternate tmpdir for the transport you're using, or by talking to your administrator about updating permissions for the directory.

My task fails mysteriously

Try running Bolt with --log-level debug to see the exact output from your task.

Make sure your task executable starts with a shebang (#!) line indicating the interpreter to use and verify that the executable is present on the target system. For example, if you write a Python task and include the line: #!/usr/bin/env python, Bolt attempts to execute the script using the default python executable on the target system.

Bolt can't connect to my hosts over SSH

Host key verification failures

This will show up as an error similar to the following:

fingerprint SHA256:6+fv7inQSgU2DuYF5NolTlGF6xM8RBRTw1W6B9rbHkc is unknown for "hostname.example.com,10.16.112.82"

When connecting over SSH, Bolt checks the host key against the fingerprint in ~/.ssh/known_hosts to verify the host is the one it's expecting to connect to. This error means that there is no key for the host in ~/.ssh/known_hosts, so Bolt doesn't know how to tell if it's the right host.

If you can connect to the host over SSH outside Bolt, you can store the SSH host key fingerprint with ssh-keyscan hostname.example.com >> ~/.ssh/known_hosts.

You can disable this check entirely with --no-host-key-check on the CLI or the host-key-check: false option under the config: ssh section of inventory.yaml. Note that doing so will reduce the security of your SSH connection.

config:
  ssh:
    host-key-check: false

Timeout or connection refused

By default, Bolt tries to connect over the standard SSH port 22. If you need to connect over a different port, either include the port in the name of the target (hostname.example.com:2345) or set it in your Bolt config or inventory.

Bolt can't connect to my Windows hosts

Timeout or connection refused

By default, Bolt tries to connect over SSH. Make sure you've specified the winrm protocol for the target. There are three ways to specify winrm:

Include the winrm in the name of the target. For example: winrm://hostname.example.com
Pass --transport winrm on the CLI
Set the winrm transport in your config or inventory file:
```
# inventory.yaml
...
config:
  transport: winrm
```

If you're still getting "connection refused" messages, try disabling SSL. By default, Bolt connects to targets over WinRM using the HTTPS port 5986. Your target may not be set up to connect over HTTPS. If you disable SSL, Bolt connects to the target using the HTTP port 5985. You can disable SSL in one of the following ways:

Pass --no-ssl on the CLI

Set the ssl key to false in your config or inventory file:

# inventory.yaml
...
config:
  transport: winrm
  winrm:
    ssl: false

Puppet log functions are not logging to the console

The default log level for the console is warn. If you use a notice function in a plan, Bolt does not print it to the console. When you have messages you want to be printed to the console regardless of log level you should use the out::message plan function. The out::message function is not available for use in an apply block and only accepts string values.

If you need to send a message that is not a string value or is in an apply block, you can use the warning Puppet log function.

If you only wish to see the output in the console when executing your plan with the --log-level debug command-line option, use the notice Puppet log function. The notice function sets the console log level to debug for that run.

For more information, see the docs for configuring Bolt's log level.

'Extensions are not built' error message

If you see a gem related error similar to the following:

    Ignoring nokogiri-1.10.2 because its extensions are not built. Try: gem pristine nokogiri --version 1.10.2
    Ignoring unf_ext-0.0.7.5 because its extensions are not built. Try: gem pristine unf_ext --version 0.0.7.5

Use the Bolt-provided gem command to reinstall/install these gems. For example:

    sudo /opt/puppetlabs/bolt/bin/gem pristine nokogiri --version 1.10.2
    sudo /opt/puppetlabs/bolt/bin/gem pristine unf_ext --version 0.0.7.5

Certificate verify failed when installing modules

When running on Windows, Bolt automatically sets the SSL_CERT_DIR and SSL_CERT_FILE environment variables if they are not already set. Assuming a default install location, the variables are set to the following directory and certificate, which are installed with the Bolt package:

SSL_CERT_DIR = C:\Program Files\Puppet Labs\Bolt\ssl\certs
SSL_CERT_FILE = C:\Program Files\Puppet Labs\Bolt\ssl\cert.pem

If you see an SSL connection error similar to the following when running on Windows:

SSL_connect returned=1 errno=0 state=error: certificate verify failed (unable to get local issuer certificate)

Set the SSL_CERT_DIR and SSL_CERT_FILE environment variables to use a valid certificate and certificate directory.
