Puppet - test if a package already defined?

Question

I\'m writing some puppet modules and have a package defined in two modules hence get the following error:

err: Could not retrieve catalog from remote server: Err         


        

Answer 1

One cleaner way (among multiple ways) is to create a virtual package resource and then realize it. You can realize the same virtual package multiple times without error.

@package { 'gnome-session-fallback':
    ensure => installed,
}

And then where you need it:

realize( Package[ 'gnome-session-fallback' ] )
