Puppet

We use the Tidy resource to clean up old apt files from /var/cache/apt/archives, and after upgrading from 2.7.6 to 2.7.9, it is no longer able to tidy more than file per Puppet agent run. I now receive a warning that says “appears to have a negative number of dependencies”

The Tidy resource code that generates this error is very simple:

tidy{'/var/cache/apt/archives':
  age     => '1d',
  rmdirs  => false,
  recurse => true,
  matches => '*.deb',
}
