- Change the repository from Enterprise to No-Subscription to receive updates without a paid license.
- Refresh the package list and run the upgrade directly from the Proxmox web interface.
- The no-subscription repository is suitable for home labs but isn’t recommended for production servers.
- Back up your server before installing updates to reduce the risk of data loss if something goes wrong.
On Proxmox, you can update the server to the latest version. In this guide, you will learn how to do so via the web interface.
Although you can install Proxmox for free, you typically need a paid subscription to receive updates. However, if you have a Proxmox server for personal use, you can change the update repository to receive updates without a subscription.
The only caveat to this approach is that the updates come from Proxmox’s pre-release channel, not the stable channel. However, updates available through the pre-release channel are stable enough, but it’s not recommended for a production environment.
In this guide, you will learn the steps to update a Proxmox server. It’s important to back up the server before updating, as there is always a chance of problems during or after the installation.
Update Proxmox server without subscription
To update Proxmox without a subscription to the latest version, use these steps:
-
Open Proxmox (web).
-
Choose the server from the left navigation pane.
-
Under the “Updates” menu, click on Repositories.
-
Select the “enterprise.proxmox.com/debina/pve” repository URI and click the Disable button.
-
Under the “APT Repositories” section, click the Add button.
-
Click the OK button in the “No valid subscription” message.
-
Choose the No-Subscription option in the “Repository” setting.
-
Click the Add button.
-
Click on Updates from the left pane.
-
Click the Refresh button.
-
Click the OK button again.
-
Confirm the task completed “OK.”
-
Close the Task viewer with the button in the top-right corner.
-
Click the Upgrade button to launch the upgrade process.
-
Type “Y” and press Enter to update Proxmox.
-
Type “reboot” to restart the server.
Once you complete the steps, the Proxmox server will automatically download and install the updates.
If you have a Proxmox subscription, you can quickly update the server by going to Proxmox > Updates and clicking the “Upgrade” button. You only need to ensure that, in Proxmox > Updates > Repositories, the “enterprise.proxmox.com/debina/pve” repository URI is enabled.
