cron-daemon-common binary package in Ubuntu Oracular armhf

 The cron daemon is a background process that runs particular programs at
 particular times (for example, every minute, day, week, or month), as
 specified in a crontab. By default, users may also create crontabs of
 their own so that processes are run on their behalf.
 .
 This package provides configuration files which must be there to
 define scheduled process sets.
