Proxmox VE uses APT as its package management tool like any other Debian-based system.

Proxmox VE automatically checks for package updates on a daily basis. The root@pam user is notified via email about available updates. From the GUI, the Changelog button can be used to see more details about an selected update.

Repositories are a collection of software packages, they can be used to install new software, but are also important to get new updates.

You need valid Debian and Proxmox repositories to get the latest security updates, bug fixes and new features.

APT Repositories are defined in the file /etc/apt/sources.list and in .list files placed in /etc/apt/sources.list.d/.

Since Proxmox VE 7, you can check the repository state in the web interface. The node summary panel shows a high level status overview, while the separate Repository panel shows in-depth status and list of all configured repositories.

Basic repository management, for example, activating or deactivating a repository, is also supported.

In a sources.list file, each line defines a package repository. The preferred source must come first. Empty lines are ignored. A # character anywhere on a line marks the remainder of that line as a comment. The available packages from a repository are acquired by running apt-get update. Updates can be installed directly using apt-get, or via the GUI (Node → Updates).

File /etc/apt/sources.list

deb http://deb.debian.org/debian bookworm main contrib deb http://deb.debian.org/debian bookworm-updates main contrib # security updates deb http://security.debian.org/debian-security bookworm-security main contrib

Proxmox VE provides three different package repositories.

This is the recommended repository and available for all Proxmox VE subscription users. It contains the most stable packages and is suitable for production use. The pve-enterprise repository is enabled by default:

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

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

You can disable this repository by commenting out the above line using a # (at the start of the line). This prevents error messages if your host does not have a subscription key. Please configure the pve-no-subscription repository in that case.

As the name suggests, you do not need a subscription key to access this repository. It can be used for testing and non-production use. It’s not recommended to use this on production servers, as these packages are not always as heavily tested and validated.

We recommend to configure this repository in /etc/apt/sources.list.

File /etc/apt/sources.list

deb http://ftp.debian.org/debian bookworm main contrib deb http://ftp.debian.org/debian bookworm-updates main contrib # Proxmox VE pve-no-subscription repository provided by proxmox.com, # NOT recommended for production use deb http://download.proxmox.com/debian/pve bookworm pve-no-subscription # security updates deb http://security.debian.org/debian-security bookworm-security main contrib

This repository contains the latest packages and is primarily used by developers to test new features. To configure it, add the following line to /etc/apt/sources.list:

sources.list entry for pvetest

deb http://download.proxmox.com/debian/pve bookworm pvetest

The pvetest repository should (as the name implies) only be used for testing new features or bug fixes.

This repository holds the enterprise Proxmox VE Ceph 19.2 Squid packages. They are suitable for production. Use this repository if you run the Ceph client or a full Ceph cluster on Proxmox VE.
