Access Server: Unable to Install OpenVPN Access Server in Raspberry Pi Due to libmariadb3 Dependency

Overview

When installing Access Server on a Raspberry Pi running Ubuntu 24, the installation may fail with the following error:

The following packages have unmet dependencies: 
openvpn-as : Depends: libmariadb3 (>= 1:10.11.14-0ubuntu0.24.04.1) but it is not going to be installed 
E: Unable to correct problems, you have held broken packages.

In Access Server 3.0.0, the MySQL client library was replaced with the MariaDB client library due to licensing changes. This error occurs when the package manager can’t locate the required MariaDB client version in the configured repositories.

Step 1: Verify the configured repositories

The required MariaDB client version is available in the noble-updates suite for Ubuntu 24. If this suite isn’t included in your repository configuration, the system can’t locate the required package version.

To check your repository configuration, connect to the Raspberry Pi console, obtain root privileges, and run:

cat /etc/apt/sources.list.d/ubuntu.sources

Example output (snippet):

## See the sources.list(5) manual page for further settings. 
Types: deb 
URIs: http://ports.ubuntu.com/ubuntu-ports/ 
Suites: noble 
Components: main restricted universe multiverse 
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg

In this example, the noble-updates suite isn’t listed under Suites.

Step 2: Add the required suite

If noble-updates isn’t listed, update the repository configuration:

1. Connect to the Rasbperry Pi console and get root privileges.

2. Use the following command to open the file for editing:

   nano /etc/apt/sources.list.d/ubuntu.sources

3. Update the Suites line:

   Suites: noble noble-updates

4. Press CTRL + X, and then Y to save the changes.

5. Run apt update.

After updating the repositories, run the installation script again. The error should no longer appear.
