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 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.

Note 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

screenshot/gui-node-repositories.png

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).

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.

Proxmox VE Enterprise Repository

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

Please note that you need a valid subscription key to access the pve-enterprise repository. We offer different support levels, which you can find further details about at https://proxmox.com/en/proxmox-virtual-environment/pricing.

Note 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

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

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

Ceph Squid Enterprise Repository

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.

File /etc/apt/sources.list.d/ceph.list
deb https://enterprise.proxmox.com/debian/ceph-squid bookworm enterprise

Ceph Squid No-Subscription Repository

This Ceph repository contains the Ceph 19.2 Squid packages before they are moved to the enterprise repository and after they where on the test repository.

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

Ceph Squid Test Repository

This Ceph repository contains the Ceph 19.2 Squid packages before they are moved to the main repository. It is used to test new Ceph releases on Proxmox VE.

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.

See the respective upgrade guide for details.

Debian Firmware Repository

Starting with Debian Bookworm (Proxmox VE 8) non-free firmware (as defined by DFSG) has been moved to the newly created Debian repository component non-free-firmware.

Enable this repository if you want to set up Early OS Microcode Updates or need additional Runtime Firmware Files not already included in the pre-installed package pve-firmware.

To be able to install packages from this component, run editor /etc/apt/sources.list, append non-free-firmware to the end of each .debian.org repository line and run apt update.

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
