Disabling a Proxmox subscription


A fresh installation of the Proxmox VE without subscriptions will display a message upon login to Proxmox GUI, as shown in the following screenshot:

This is because an enterprise repository is enabled by default. If you decide not to get any Proxmox subscriptions and continue using the fully Free version, you will have to disable the enterprise repository.

Getting ready

Login to the Proxmox node through a console or SSH. An enterprise repository can only be disabled through CLI.

How to do it…

The enterprise repository is listed in /etc/apt/sources.list.d/pve-enterprise.list. We have to comment out the line to disable the repository:

# nano /etc/apt/sources.list.d/pve-enterprise.list
#deb https://enterprise.proxmox.com/debian wheezy pve-enterprise

Add the Proxmox No-Subscription repository as follows:

# nano /etc/apt/sources.list
deb http://download.proxmox.com/debian wheezy pve-no-subscription

How it works…

No restart of services or reboot is required to apply the changes. Log out from the Proxmox GUI and log back in to see if the changes were applied correctly. The "no subscription" message box should not pop-up after login. Subscriptions can be managed from the Proxmox GUI under the Subscription tab. Here is a screenshot of a nonsubscribed Proxmox node:
