The crontab will be installed and begin running if there are no errors. The "%" character is used as newline delimiter in cron commands. Code: root 685 1 0 10:57 ? 00:00:00 anacron -s root 1084 685 0 11:02 ? 00:00:00 /bin/sh -c nice run-parts --report /etc/cron.daily root 1085 1084 0 11:02 ? 00:00:00 run-parts I understand this is done via "upstart" and so you might like to try purging and reinstalling this package in case it has been corrupted.
