Proxmox VE is using APT as package management system. Updates can be installed via GUI or via CLI. Updating via GUI is introduced with Proxmox VE 3.1. For detailed update instructions see always Downloads.
The list of repositories is defined in /etc/apt/sources.list and or /etc/apt/sources.d/.
Beginning with Proxmox VE 3.1, the default and recommended repository is the Proxmox VE Enterprise Repository (pve-enterprise). To be qualified to access Proxmox VE Enterprise Repository, each of your Proxmox VE Servers need a valid Subscription Key. For more details about Proxmox VE Subscriptions, see http://www.proxmox.com/proxmox-ve/pricing
Proxmox VE 3.x
Proxmox VE 3.x is based on Debian 7.x (Wheezy).
Proxmox VE Enterprise Repository
This is the default, stable and recommended repository, available for all Proxmox VE Subscription users.
cat /etc/apt/sources.list.d/pve-enterprise.list deb https://enterprise.proxmox.com/debian wheezy pve-enterprise
As soon as updates are available, the root@pam user is notified via email about the available new packages. On the GUI, the change-log of each package can be viewed (if available), showing all details of the update. You will never miss important security fixes.
This repo is only accessible over https and you need to have a valid Subscription Key on your host. This key is used for authentication.

Proxmox VE No-Subscription Repository
The pve-no-subscription repo can be used for testing and non-production use. Its not recommended to run on production servers as these packages are not always heavily tested and validated. As the name suggests, there is no Proxmox VE Subscription Key needed to access this repository.
In order to use the pve-no-subscription repository, check and adapt your sources.list:
deb http://ftp.debian.org/debian wheezy main contrib # PVE pve-no-subscription repository provided by proxmox.com, NOT recommended for production use deb http://download.proxmox.com/debian wheezy pve-no-subscription # security updates deb http://security.debian.org/ wheezy/updates main contrib
To prevent error messages accessing the Proxmox VE Enterprise Repository (if you have no Subscription key), you can disable this repo by commenting out the following line:
nano /etc/apt/sources.list.d/pve-enterprise.list # deb https://enterprise.proxmox.com/debian wheezy pve-enterprise
Outdated: Stable repository (pve)
