How to Install Security Updates Automatically on Debian and Ubuntu
|
||
============================================================
|
||
|
||
It has been said before -and I couldn’t agree more- that some of the best system administrators are those who seem (note the use of the word seem here) to be lazy all the time.
|
||
|
||
While that may sound somewhat paradoxical, I bet it must be true in most cases – not because they are not doing the job they are supposed to be doing, but rather because they have automated most of it.
|
||
|
||
One of the critical needs of a Linux system is to be kept up to date with the latest security patches available for the corresponding distribution.
|
||
|
||
In this article we will explain how to set up your Debian and Ubuntu system to auto install (or update) essential security packages or patches automatically when needed.
|
||
|
||
Other Linux distributions such as [CentOS/RHEL configured to install security updates automatically][1].
|
||
|
||
Needless to say, you will need superuser privileges in order to perform the tasks outlined in this article.
|
||
|
||
### Configure Automatic Security Updates On Debian/Ubuntu
|
||
|
||
To begin, install the following packages:
|
||
|
||
```
|
||
# aptitude update -y && aptitude install unattended-upgrades apt-listchanges -y
|
||
```
|
||
|
||
where apt-listchanges will report what has been changed during an upgrade.
|
||
|
||
Next, open /etc/apt/apt.conf.d/50unattended-upgrades with your preferred text editor and add this line inside the Unattended-Upgrade::Origins-Pattern block:
|
||
|
||
```
|
||
Unattended-Upgrade::Mail "root";
|
||
```
|
||
|
||
Finally, use the following command to create and populated the required configuration file (/etc/apt/apt.conf.d/20auto-upgrades) to activate the unattended updates:
|
||
|
||
```
|
||
# dpkg-reconfigure -plow unattended-upgrades
|
||
```
|
||
|
||
Choose `Yes` when prompted to install unattended upgrades:

Configure Unattended Security Updates on Debian
|
||
|
||
then check that the following two lines have been added to /etc/apt/apt.conf.d/20auto-upgrades:
|
||
|
||
```
|
||
APT::Periodic::Update-Package-Lists "1";
|
||
APT::Periodic::Unattended-Upgrade "1";
|
||
```
|
||
|
||
And add this line to make reports verbose:
|
||
|
||
```
|
||
APT::Periodic::Verbose "2";
|
||
```
|
||
|
||
Last, inspect /etc/apt/listchanges.conf to make sure notifications will be sent to root.
