After installing updates on Ubuntu 14.04.1 LTS, an error with the text began to appear daily:
Please run this cronjob as user amavis
run-parts: /etc/cron.daily/amavisd-new exited with return code 1
The reason was the update of amavis and the migration when updating the configuration file /etc/cron.daily/amavisd-new in /etc/cron.d/amavisd-new, and for some reason the old file was not deleted.
As a result, the solution to this problem – make sure that the configuration file /etc/cron.d/amavisd-new is present and delete the old file /etc/cron.daily/amavisd-new.
