-When `Exec['apt_update']` is triggered, it generates a `Notice` message. Because the default [logging level for agents](https://docs.puppet.com/puppet/latest/configuration.html#loglevel) is `notice`, this causes the repository update to appear in logs and agent reports. Some tools, such as [The Foreman](https://www.theforeman.org), report the update notice as a significant change. To eliminate these updates from reports, set the [loglevel](https://docs.puppet.com/puppet/latest/metaparameter.html#loglevel) metaparameter for `Exec['apt_update']` above the agent logging level:

+> **NOTE:** Every `Exec['apt_update']` run will generate a corrective change, even if the apt caches are not updated. For example, setting an update frequency of `always` can result in every Puppet run resulting in a corrective change. This is a known issue.
