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

Repositories in Proxmox VE

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/.

Repository Management

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.

Sources.list

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).

Proxmox VE provides three different package repositories.

Proxmox VE Enterprise Repository

This is the default, stable, and recommended repository, 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

The root@pam user is notified via email about available updates. Click the Changelog button in the GUI to see more details about the selected update.

You need a valid subscription key to access the pve-enterprise repository. Different support levels are available. Further details can be found at https://www.proxmox.com/en/proxmox-ve/pricing.

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.

Proxmox VE No-Subscription Repository

This is the recommended repository for testing and non-production use. Its packages are not as heavily tested and validated. You don’t need a subscription key to access the pve-no-subscription repository.

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

Proxmox VE Test Repository

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.

Ceph Quincy Enterprise Repository

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

File

/etc/apt/sources.list.d/ceph.list

deb https://enterprise.proxmox.com/debian/ceph-quincy bookworm enterprise

Ceph Quincy No-Subscription Repository

This Ceph repository contains the Ceph Quincy packages before they are moved to the enterprise repository and after they where on the test repository.

It’s recommended to use the enterprise repository for production machines.

File

/etc/apt/sources.list.d/ceph.list

deb http://download.proxmox.com/debian/ceph-quincy bookworm no-subscription

Ceph Quincy Test Repository

This Ceph repository contains the Ceph Quincy packages before they are moved to the main repository. It is used to test new Ceph releases on Proxmox VE.

File

/etc/apt/sources.list.d/ceph.list

deb http://download.proxmox.com/debian/ceph-quincy bookworm test

Older Ceph Repositories

Proxmox VE 8 doesn’t support Ceph Pacific, Ceph Octopus, or even older releases for hyper-converged setups. For those releases, you need to first upgrade Ceph to a newer release before upgrading to Proxmox VE 8.

SecureApt

The Release files in the repositories are signed with GnuPG. APT is using these signatures to verify that all packages are from a trusted source.

If you install Proxmox VE from an official ISO image, the key for verification is already installed.

If you install Proxmox VE on top of Debian, download and install the key with the following commands:

wget https://enterprise.proxmox.com/debian/proxmox-release-bookworm.gpg -O /etc/apt/trusted.gpg.d/proxmox-release-bookworm.gpg

Verify the checksum afterwards with the sha512sum CLI tool:

# sha512sum /etc/apt/trusted.gpg.d/proxmox-release-bookworm.gpg 7da6fe34168adc6e479327ba517796d4702fa2f8b4f0a9833f5ea6e6b48f6507a6da403a274fe201595edc86a84463d50383d07f64bdde2e3658108db7d6dc87 /etc/apt/trusted.gpg.d/proxmox-release-bookworm.gpg

or the md5sum CLI tool:

# md5sum /etc/apt/trusted.gpg.d/proxmox-release-bookworm.gpg 41558dc019ef90bd0f6067644a51cf5b /etc/apt/trusted.gpg.d/proxmox-release-bookworm.gpg

Proxmox VE 7.x Repositories

Proxmox VE 7.x is based on Debian 11.x (“bullseye”). Please note that this release is out of date (see the FAQ support table). Existing installations should be updated. Nevertheless access to these repositories is still provided.

Outdated: stable Repository pve

This repository is a leftover to ease the update to 3.1. It will not get any updates after the release of 3.1. Therefore the repository needs to be removed after the upgrade to 3.1.
