systemd-cron binary package in Ubuntu Oracular armhf

 This is a generator that dynamicaly translates /etc/crontab,
 /etc/cron.{d|hourly|daily|weekly|monthly|yearly}/*
 and user cronjobs into systemd .timer & .service units.
 .
 Output from the commands is usually mailed to the system administrator
 (or to the user in question); you should probably install a mail system
 as well so that you can receive these messages.
