It looks like a syntax issue (at a minimum):

package { "sudo-ldap":

ensure => present,

require => Package["sudo],

}

There isn't a trailing doublequote for the "sudo" line.

Hello Folks!

I am trying to learn puppet. Installed the puppet 3.0.2 and configured one node as the master and the other as the client. Generated the certs and all that. But, I seem to be doing something wrong wrt to the init.pp file. Attached is exact error and my current server configuration. Any help in helping me fix this issue is appreciated:

[root@pupclient ~]# puppet agent --test
Info: Retrieving plugin
Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Could not find class sudo for pupclient on node pupclient

Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run

puppet.conf file on the client is pointed to the server which I named as puppet and which the client is able to resolve in DNS.
[root@pupclient ~]# cat /etc/puppet/puppet.conf

[main]
# The Puppet log directory.
# The default value is '$vardir/log'.

logdir = /var/log/puppet

# Where Puppet PID files are kept.

# The default value is '$vardir/run'.
rundir = /var/run/puppet

# Where SSL certificates are kept.
# The default value is '$confdir/ssl'.

ssldir = $vardir/ssl
server=puppet

[agent]
# The file in which puppetd stores a list of the classes
# associated with the retrieved configuratiion. Can be loaded in

# the separate ``puppet`` executable using the ``--loadclasses``
# option.
# The default value is '$confdir/classes.txt'.

classfile = $vardir/classes.txt

# Where puppetd caches the local configuration. An

# extension indicating the cache format is added automatically.
# The default value is '$confdir/localconfig'.

localconfig = $vardir/localconfig

Below is the configuration on the puppet master:

[root@puppet manifests]# pwd
/etc/puppet/manifests

[root@puppet manifests]# cat site.pp

import 'nodes.pp'
$puppetserver = 'puppet'

[root@puppet manifests]# cat nodes.pp
node 'pupclient' {

include sudo
package {'firefox': ensure => present}
}

[root@puppet manifests]# pwd
/etc/puppet/modules/sudo/manifests

[root@puppet manifests]# ls -l
total 4
-rw-r--r-- 1 root root 327 Jan 19 23:15 init.pp

[root@puppet manifests]# cat init.pp
class sudo {
package { sudo:
ensure => present,
}
if $operatingsystem == "Ubuntu" {

package { "sudo-ldap":
ensure => present,
require => Package["sudo],
}
}

file { "/etc/sudoers":
owner => root,
group => root,
mode => 0440,
source => "puppet://$puppetserver/modules/sudo/etc/sudoers",

require => Package["sudo"],
}
}

Is this error result of a syntax issue or something else?

Something to help you avoid it in the future:

Put all of your puppet manifests into a git repo (very good practice to get setup right away), and then put a git pre-commit hook that uses puppet parser validate to check for syntax errors. This will basically not let you commit new manifests if they have syntax problems. Much more efficient troubleshooting.
