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.
If you missed the previous blog posts of this series, you can find them here:
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.
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.
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.

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.
Then, add the following line to point to the no subscription repository:
deb http://download.proxmox.com/debian/pve bookworm pve-no-subscription
Save and exit the file by pressing Ctrl+X, then Y, and Enter.
Proxmox 8.x requires an additional step of updating the Ceph repository list. This was not needed in previous versions like 7.x.

Open the Ceph repository list file located at /etc/apt/sources.list.d/ceph.list
And, edit using the following command.
nano /etc/apt/sources.list.d/ceph.list
In this file, you’ll see a line pointing to the Enterprise repository for Ceph updates. Comment out this line and add the following line to point to the no subscription repository:
deb http://download.proxmox.com/debian/ceph-quincy bookworm no-subscription
Save and exit the file by pressing Ctrl+X, then Y, and Enter.
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
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.
Switching to the no subscription repository is a straightforward process that allows you to keep your Proxmox VE server updated without needing a subscription. This is ideal for home lab environments where budget constraints are a consideration.
Remember, the no subscription repository is fully supported within the terms of use of Proxmox, so you can use it with confidence.
If you have any questions or run into issues, there are plenty of resources available. The Proxmox community forums are a great place to start, and you can also find detailed guides and tutorials on various blogs and websites.
Happy labbing, and enjoy your Proxmox VE setup!
