Indeed, I should have paid more attention t the actual error.

Thanks for the info.

Hello everyone.

I've been toying around with puppet and something happened that seems
strange to me.
In site.pp I have the following:

node default {

   # This is where you can declare classes for all nodes.

   # Example:

   #   class { 'my_class': }

   #  class { 'lamp': }

   package {'php':

   ensure   => present,

   before => File['/etc/php.ini'],

   }


   file {'/etc/php.ini':

   ensure => file,

   }


   package {'httpd':

 ensure => present,

   }


   service {'httpd':

   ensure  => running,

   enable=> true,

   require => Package['httpd'],

   subscribe => File['/etc/php.ini'],

   }


   package {'mysql-server':

   ensure => 'present',

   }


   service {'mysqld':

   ensure  => running,

   enable=> true,

   require => Package['mysql-server'],

   }

}


[I know about classes etc, this was just for easy testing. ]

Now, if I change the httpd resource to

package {'httpd':

   ensure => absent,

   }

I get the following error:

Error: Execution of '/bin/rpm -e httpd-2.2.3-82.el5.centos.i386'
returned 1: error: Failed dependencies:

httpd-mmn = 20051115 is needed by (installed)
php-5.1.6-40.el5_9.i386


Error: /Stage[main]//Node[default]/Package[httpd]/ensure: change
from 2.2.3-82.el5.centos to absent failed: Execution of

This seems strange to me, because I never declared a require dependency
from php to httpd.
The only thing is that the httpd  service subscribes to the php.ini
file. I could understand this error if the direction of this dependency
was the other way around, but not this way.


	It's important when troubleshooting Puppet to separate the Puppet error 
reported from the subsystem error that may have caused Puppet to report 
a failure. This seems to confuse more frequently that I would have thought.


	In the case above the Puppet error is: "Error: 
/Stage[main]//Node[default]/Package[httpd]/ensure: change from 
2.2.3-82.el5.centos to absent failed" and the error Puppet is passing on 
comes from rpm is "Failed dependencies: httpd-mmn = 20051115 is needed 
by (installed) php-5.1.6-40.el5_9.i386"
