Secure your Ubuntu server with ease: automate security package updates

Protect your Ubuntu server effortlessly by automating security package updates. Safeguard your system from potential threats with ease.

If you want to automatically install security updates on your Ubuntu server, you can use the unattended-upgrades package. This package will automatically install security updates for your system's packages.

How to activating automatic security updates on Ubuntu

Install the unattended-upgrades package:

sudo apt-get update && sudo apt-get install unattended-upgrades

Edit the configuration file /etc/apt/apt.conf.d/50unattended-upgrades:

sudo nano /etc/apt/apt.conf.d/50unattended-upgrades

Uncomment the following line by removing the // at the beginning of the line, and change false to true if you want the system to reboot automatically after installing updates.

//Unattended-Upgrade::Automatic-Reboot "false";

Edit the configuration file /etc/apt/apt.conf.d/20auto-upgrades:

sudo nano /etc/apt/apt.conf.d/20auto-upgrades

Uncomment the following lines by removing the // at the beginning of each line:

APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Unattended-Upgrade "1";

These lines configure the system to update the package lists once a day and to automatically install security updates.

Optionally, you can also configure email notifications to be sent when updates are installed by adding your email address to the /etc/apt/apt.conf.d/50unattended-upgrades configuration file:

Unattended-Upgrade::Mail "[email protected]";

Save the changes and exit the text editor.

Your Ubuntu system is now configured to automatically download and install security updates. You can check the log files located at /var/log/unattended-upgrades/ to ensure that updates are being installed correctly.

It is important to note that automatic updates may not always be desirable in certain environments, such as production servers where manual intervention may be required to ensure that updates do not cause any issues. Therefore, it is important to carefully consider whether automatic updates are appropriate for your particular use case.
