How to Upgrade Apache on Debian 12/11/10

Debian, one of the most robust and widely used Linux distributions, is applauded for its stability, which emanates from its conservative approach to software packaging. It often lags in including the latest software builds, choosing stability over cutting-edge features. This conservative approach, while advantageous in many respects, can be a limiting factor when the user’s specific use-case or environment necessitates the utilization of the latest builds of certain software, such as Apache.

Apache HTTP Server is an open-source HTTP server for modern operating systems, including UNIX, Microsoft Windows, and others. It’s highly configurable and robust, with many useful features. However, the version available in Debian’s official repositories might not always be up-to-date with the latest stable builds of Apache.

Regardless of the reason you choose to upgrade Apache using Ondřej Surý’s Debian PPA, it’s essential to understand the process. In the subsequent guide, we aim to provide detailed instructions that make this task less daunting, even for less experienced system administrators.

The guide will demonstrate how to upgrade Apache 2 on Debian 12 (Bookworm), Debian 11 (Bullseye), or Debian 10 (Buster), ensuring you’re armed with the knowledge to keep your system updated, secure, and running efficiently.

Step 1: Updating Your Debian System

In any system upgrade or software installation process, starting with an updated system is fundamental. This approach aims to harmonize the existing software versions with the new installations, leading to a smooth and successful upgrade process. Updating your Debian system before you begin ensures that all packages on your system are up-to-date and compatible with the forthcoming Apache installation.

The following command updates your local list of software, ensuring your system is aware of the latest versions:

sudo apt update

Next, proceed with the system upgrade, ensuring that your system is running the latest software versions. This process aids in enhancing the overall system performance and security. Use the following command to upgrade your Debian system:

sudo apt upgrade

Step 2: Integrating the Apache LaunchPAD PPA

The first major step towards upgrading the Apache web server to its latest version is integrating Ondřej Surý’s repository into your Debian system. Before this, however, you need to install a few prerequisite packages that facilitate this integration. These packages include dirmngr, curl, ca-certificates, software-properties-common, and apt-transport-https, which are critical for downloading and managing the necessary keys and repositories.

Execute the following command to install these packages:

sudo apt install dirmngr curl ca-certificates software-properties-common apt-transport-https

After ensuring that the necessary packages are installed, proceed to import Ondřej Surý’s repository. This process is accomplished using the curl command, which downloads the repository’s setup script, and the bash command, which runs the downloaded script:

curl -sSL | sudo bash -x

Step 3: Installing or Upgrading Apache

After successfully adding the Apache LaunchPAD PPA, the next step involves synchronizing your local package database with the server’s repositories. This update is to ensure that your system recognizes the newly added repository. Run the following command to update your repository:

sudo apt update

With the repository added, you can now proceed to install the latest Apache version or upgrade the existing one. It’s recommended to run the installation command even if Apache is already present on your system. This strategy ensures that the latest version is installed and all required dependencies are up-to-date. Use the following command to install the latest Apache version:

sudo apt install apache2

Upon completing the Apache installation, it’s essential to verify which version is installed and its source. Using the apt-cache policy command, you can confirm that Apache2 has been installed from Ondřej Surý’s repository. Execute the following command:

apt-cache policy apache2

Please be aware that at the moment this guide was published, Debian 12 (Bookworm) users may not see an updated version, as the distribution was recently released. However, by importing the repository now, you’ll be primed to receive the newer version as soon as it’s released.

Verifying Apache Status

To verify that Apache is running correctly, the systemctl command proves handy. This command checks the Apache status and confirms its operation as expected. Run the following command to check Apache’s status:

systemctl status apache2

If Apache isn’t activated or running, you can use the following command to start the web server application:

sudo systemctl start apache2

To ensure Apache is enabled to start on system boot, you can use the following command:

Using Ondřej Surý’s repository ensures your Apache version is consistently maintained and updated. Whenever a new version of Apache is available, the repository is typically updated within days to weeks, courtesy of Ondřej Surý’s extensive maintenance work on the PHP, Nginx, and Apache repositories.

Enhancing Your Debian System: Post-Installation Tips for Apache

Once you’ve successfully installed or upgraded Apache on your Debian system, some additional steps can optimize the system and ensure smooth functioning. This segment focuses on firewall configurations, updating procedures, and even rollback steps if necessary.

Configuring UFW Firewall for Apache

Security is paramount when dealing with web servers. A critical security measure is appropriately configuring your firewall. If you’re using UFW (Uncomplicated Firewall), you must modify the firewall rules to allow outside access to the default web ports after installing or upgrading Apache. This change is necessary to ensure your web server is accessible to visitors.

During the Apache installation, the software registers itself with UFW, creating several profiles for easy configuration. However, if UFW is not installed on your system, you can do so with the following command:

sudo apt install ufw

Once installed, ensure UFW starts on boot and is currently active with the following command:

sudo ufw enable

You can view the available Apache profiles by running the following command:

sudo ufw app list

The output will typically show three profiles: Apache, Apache Full, and Apache Secure. The Apache profile only allows HTTP traffic on port 80, Apache Secure allows HTTPS traffic on port 443, and Apache Full allows both.

In this guide, we will assume that SSL has not been set up and enable the Apache profile using the following command:

sudo ufw allow 'Apache'

After execution, the rules will be added for both IPV4 and IPV6. If needed, you can disable this profile later and enable the Apache Full or Apache Secure profiles instead.

Updating Apache

Keeping your Apache server updated is a crucial maintenance task. The APT package manager in Debian makes it easy to check for updates and install them if available. Start by refreshing the local list of software packages with:

sudo apt update

If an update for Apache is available, you can upgrade it using the following command:

sudo apt upgrade apache2

These steps will help keep your Apache installation secure and equipped with the latest features.

Reverting the Apache Upgrade

If, for any reason, you need to rollback the upgraded Apache version and restore the default Debian version, follow the steps below.

Start by stopping the Apache service with:

sudo systemctl stop apache2

Next, remove Apache using the following command:

sudo apt remove apache2

If you imported the PPA to upgrade Apache, you could remove it using:


To ensure your system recognizes the changes to the APT sources, update the package lists:

sudo apt update

At this point, you can reinstall the standard Debian version of Apache.
