Recently (since Ubuntu 7.10), the aptitude action 'upgrade' is deprecated. There are now two ways to upgrade, a safe one (conservative, if an update needs to add or remove dependencies, it won't update) and a full one (it will always upgrade even though it impacts other packages by adding them or removing them, previously called 'dist-upgrade'). The actions are now 'safe-upgrade' or 'full-upgrade'. See the manual page of aptitude (man aptitude) for more details. Once you are complete, you want to make the file executable.

This script will run once weekly and it installs all available packages from the security repository. It also generates a log in /var/log/apt-security-updates for later inspection in case something goes wrong. This script will output information to a log file, so to prevent this log file from getting too large we need to make sure it gets rotated out. To do this, we'll use the logrotate utility, which comes with Ubuntu. Press Alt+F2 and type this command:
Paste this into the editor, save, and exit:
This will rotate the log file every week (weekly), or if it's over 250kB in size (size 250k), compressing old versions (compress). The previous two log files will be kept (rotate 2), and no rotation will occur if the file is empty (notifempty). Using cron-apt to handle automatic updating
