Proxmox VE is a robust open-source solution for virtualization, widely popular among home lab enthusiasts. By default, Proxmox is configured to use Enterprise repositories that require a subscription. For home lab setups where budget constraints are a consideration, purchasing a subscription may not be feasible.

Fortunately, Proxmox provides a no subscription repository that you can use to keep your server updated without needing a subscription. In this tutorial, we’ll walk you through the process of configuring your Proxmox VE installation to use no subscription repositories.

Understanding the Need for No Subscription Repositories

When you first set up Proxmox VE, it is configured to use Enterprise repositories, which require a paid subscription for access. Without a subscription, you won’t be able to fetch updates from these repositories, which is critical for maintaining a secure and up-to-date system.

By switching to the no subscription repository, you can access updates and keep your server secure and functional, all for free and legally.

Logging into the Proxmox Web Interface

Begin by logging into the web interface of your Proxmox VE server. You might see a message stating “No valid subscription.” This message will remain even after switching to the no subscription repository, but it will not interfere with your ability to update the server.

Next, minimize the web interface and open an SSH session to your Proxmox VE server. The SSH session will allow you to edit the necessary configuration files.

Checking the Current Repository Configuration

Once logged in via SSH, it’s important to understand the current repository configuration. Execute the following commands to update and upgrade your system:

apt-get update && apt-get upgrade

You will likely see errors indicating that the system cannot fetch updates from the Enterprise repository. This is because you don’t have a valid subscription.

The error message will look something like this: “Failed to fetch enterprise.proxmox.com.” This confirms that you are currently pointed to the Enterprise repository.

Editing the Main Repository List

To switch to the no subscription repository, you need to edit the main repository list file located at /etc/apt/sources.list.d/pve-enterprise.list.

Open this file using a text editor, such as nano:

nano /etc/apt/sources.list.d/pve-enterprise.list

In this file, you’ll see a line pointing to the Enterprise repository. It will look something like this:

deb https://enterprise.proxmox.com/debian/pve bookworm pve-enterprise

Comment out this line by adding a ‘#’ at the beginning.

Save and exit the file by pressing Ctrl+X, then Y, and Enter.

Editing the Ceph Repository List

Proxmox 8.x requires an additional step of updating the Ceph repository list. This was not needed in previous versions like 7.x.

Save and exit the file by pressing Ctrl+X, then Y, and Enter.

Testing the New Configuration

With the repository files updated, it’s time to test the new configuration. Run the update and upgrade commands again:

apt-get update && apt-get upgrade

testing configuration in proxmox ve 8.1

This time, you should see that the system is able to fetch updates from the no subscription repository without any errors. This confirms that your Proxmox VE server is now successfully configured to use the no subscription repositories.
