If you’ve ever tried out Ubuntu you’ll probably know what aptitude is and how to manage packages. Updating your system is as simple as sudo aptitude udpate && sudo aptitude upgrade
This updates the package lists and presents any upgrades.
Wouldn’t it be easier if you could automate this and forget about it? That way your server can stay up to date without you ever having to worry about it. Create a file called autoupdate.sh and put the following into it:
#!/bin/bash # A script to run Aptitude and install any upgrades automatically. # Add this to /etc/cron.daily to run the script every 24 hours. # This prevents "TERM is not set, so the dialog frontend is not usable." error PATH="$PATH:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin" aptitude update aptitude safe-upgrade -y aptitude autoclean
To run this script daily move it to /etc/cron.daily (making sure it is executable).
chmod +x autoupdate.sh sudo chown root:root autoupdate.sh sudo mv autoupdate /etc/cron.daily
The update will run automatically once a day ensuring you stay up-to-date.
You can keep a check on packages that have been installed and removed via the log file that Aptitude generates.
sudo tail -n 30 /var/log/aptitude
If you want to check that an upgrade has been applied you can search for it like this
sudo cat /var/log/aptitude | grep -A 20 -B 20 php5
Or you can check the currently installed version using (this example is php5)
aptitude show php5
