and has exactly this reason: the script in question has no environment. Here is a blueprint for (cron-)scripts:

Code:
#!/bin/ksh

. /etc/environment             # for AIX
. /etc/bashrc                  # alternatively, for Linux


... here goes the rest of your code ...

I hope this helps.

NAME

       apticron - Generate a mail listing packages which are pending an upgrade

SYNOPSIS

       apticron [--cron]

DESCRIPTION

       apticron is a shell script which generates a mail with a list of all packages currently pending an upgrade, as well as summary of changes -
       using apt-listchanges - to a configurable Email address.

       apticron is mainly intended for automatic notification of pending security updates but can also be used	in  many  other  situations  where
       timely updates are necessary.

       The --cron option is only meant to be used when invoked by cron in order to run no more than once a day.

FILES

       /etc/apticron/apticron.conf
	      Configuration file, Email address to mail and profile for use with apt-listchanges are configurable.

       /etc/cron.d/apticron
	      Cron job for executing apticron daily.

       /etc/cron.daily/apticron
	      Fallback cron script for executing apticron (if no crond running or system down at designated time).

       /var/lib/misc/apticron.cron
	      Time stamp file used by apticron when invoked with --cron option.
