Troubleshooting an Access Server Installation

Abstract

Troubleshoot installation issues with OpenVPN's business VPN software, Access Server.

The recommended installation method is the installation script as offered on the Access Server Portal. If you've followed the instructions to install Access Server and are having problems, read this topic.

Situation: The installation script reported an error with apt or yum software management programs

Apt and yum are package management programs for downloading and installing new software and getting updates for installed software. Debian/Ubuntu-based systems generally use apt, while RedHat Enterprise Linux-based systems use yum. They use software repositories to retrieve and install software, which is also how Access Server is delivered.

Our Access Server installation script quickly checks to see if your operating system's package management program works correctly. If it reports a problem, there is likely a pre-existing issue with your package management program, which will prevent the installation script from proceeding with the installation of Access Server. Apt or yum must be working correctly before new software can be installed.

To troubleshoot apt or yum further, try running apt update or yum update to retrieve new information from the currently configured repositories and see if any problems are reported.

The package management programs require root privileges to retrieve and install software. If you see an error message like the one shown below, it means you need to gain root privileges first before running the script:

E: Could not open lock file /var/lib/apt/lists/lock - open (13: Permission denied)

If your operating system is no longer supported, the repositories your system is configured to use may have removed support. If you see an error message like the one shown below, it may mean your operating system is no longer supported:

E: The repository '(...)' no longer has a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.

If you are indeed on an end-of-life operating system, switching to a supported one would be advisable. In some cases, an archive repository may be available that you can use to resolve the error, but running an unsupported system that gets no security updates isn't recommended, and Access Server might not even install on it.

If the problem is a lack of internet access, see the article below on not having (direct) internet access on your server for more details on your options, such as manually downloading the installation files.

If you need further assistance with solving issues with apt or yum, contact our technical support and explain the details of your situation so that we may assist you further.

Situation: I don't want to use your Linux installation script; how can I install it manually?

We highly recommend using our installation script or prepared images from the Access Server portal. It automatically detects the correct operating system and tries to identify any possible issues.

However, downloading and executing a script to install Linux software may not be desirable in some cases due to security considerations. If this is your situation, you can use the information provided here to install the software repository, install the openvpn-as package yourself, and optionally install the openvpn-dco-dkms package for DCO support.

For servers with no internet access, see the item where you have no (direct) internet access on the server. For servers with internet access, you can use the information below to install the repository manually and install the necessary packages.

Situation: No (direct) internet access on the server.

If, for some reason, your system is isolated from the internet, the normal installation steps won't work, as they rely on having access to the official OpenVPN Access Server software repository. Installing Access Server in this situation is still possible, but it will take additional steps.

Allowing access to the Access Server software repository, even temporarily, would greatly ease the software's installation. If, for example, a proxy server may be used, then configuring the operating system and yum or apt to use this proxy may allow you to install Access Server from the software repository after all.

But if, for some reason, internet access is not possible, then only a completely manual installation remains. To that end, we have a listing of packages that you require for Access Server to be installed, which can be obtained from the Linux distribution of your choice, and separate downloads of the necessary Access Server installation binaries (deb and rpm for the various supported platforms).

Important

We highly recommend that you ensure your system can install software and updates directly from our software repository. If this isn't possible, you may use the offline installation instructions below. However, that isn't the recommended method of installing Access Server. We always recommend doing a normal online installation using our prepared images or installation script.

Offline installation instructions

If, for some reason, you can't or won't use the recommended installation via the install script or official Access Server software repository, you can instead download the packages separately to your server and install them. You must be logged on to your Linux system either on the console or via SSH, with root privileges.

Copy and paste the commands below to download the necessary package installer files and install the Access Server client bundle and the Access Server package itself.

Ubuntu 24.04 LTS, x86_64

The Access Server installation files are available for download here:

OpenVPN Access Server requires a number of libraries and programs that it depends on to be installed on your system. Normally, with internet access, the package management program will automatically detect and install the required software. If you are on a system without internet access, the package manager can't automatically download and install dependencies for you. So it will be up to you to ensure those are available to the system and installed.

When you run the command below as the root user to install Access Server and its accompanying Connect client bundle, it will list any missing dependencies.

apt install ./openvpn-as_filename.deb ./openvpn-as-bundled-clients_filename.deb

After these steps, your Access Server should be installed and awaiting further configuration.
