APT configuration for automatic cache updates
This package contains configuration snippets for the APT package manager to make it automatically update its package cache.
This is useful for systems which do not use a daemon like PackageKit to trigger cache refreshes at convenient times. The configuration will not trigger automatic installation of updates, for this functionality consider using the `unattended-upgrades` utility.
