How to solve $concat_basedir not defined error?

[Haani Niyaz]

Hi there,

I'm fairly new to puppet I am attempting to setup a dashboard for puppetdb. I came across puppetexplorer and wanted to trial it out.

I attempted to install puppetexplorer  by doing the following:

puppet module install spotify-puppetexplorer


#Added puppetexplorer to my puppet node declaration


node 'puppet' {
  include 'puppetexplorer'
}

On running the agent on the master to install puppetexplorer I get the following error (running it as root):

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: $concat_basedir not defined. Try running again with pluginsync=true on the [master] and/or [main] section of your node's '/etc/puppet/puppet.conf'. at /etc/puppet/modules/concat/manifests/setup.pp:20 on node puppet.example.com

I already tried setting pluginsync=true and however it does not make a difference. Can someone hint at what might be the problem?

Thanks.

The concat_basedir custom fact comes from the concat module https://forge.puppetlabs.com/puppetlabs/concat so on the agent, if you can run `facter concat_basedir` then puppet should be able to pick it up.

It looks like you do have the concat module installed at /etc/puppet/modules/concat, and if you have pluginsync turned on (which is on by default, fwiw) then I'm not really sure what could be the hang-up.

What does running `puppet plugin download` on the agent do? Does it fix the issue?

Thanks for the info.

`facter concat_basedir` returns empty.

`puppet plugin download` returns 'no plugins downloaded.'

Where did you set pluginsync = true?
It needs to be in the master section of the puppet.conf on your puppet master.

Which version of puppet, facter, hiera and the concat module are you using?

AFAIK pluginsync needs to be set on the agents.
On the Master you need to install the module
- puppet module install puppetlabs/concat

On the agent you need at least one puppet agent run to synchronize the required concat scripts.
If you run in hoop mode only, concat will always fail due to missing scripts.

I just had a look at the docs and pluginsync needs to be set to true
in the [main] of Both the master and the client.
https://docs.puppetlabs.com/guides/plugins_in_modules.html#enabling-pluginsync

It is on by default in puppet 3+
The default was false in earlier versions.
