.. _sysadmin_package_repositories: Debian Package Repositories --------------------------- All Debian based systems use APT_ as a package management tool. The lists of repositories are defined in ``/etc/apt/sources.list`` and the ``.list`` files found in the ``/etc/apt/sources.d/`` directory. Updates can be installed directly with the ``apt`` command line tool, or via the GUI. APT_ ``sources.list`` files list one package repository per line, with the most preferred source listed first. Empty lines are ignored and a ``#`` character anywhere on a line marks the remainder of that line as a comment. The information available from the configured sources is acquired by ``apt update``. .. code-block:: sources.list :caption: File: ``/etc/apt/sources.list`` deb http://ftp.debian.org/debian buster main contrib deb http://ftp.debian.org/debian buster-updates main contrib # security updates deb http://security.debian.org/debian-security buster/updates main contrib .. FIXME for 7.0: change security update suite to bullseye-security In addition, you need a package repository from Proxmox to get Proxmox Backup updates. .. _package_repos_secure_apt: 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 Backup Server from an official ISO image, the verification key is already installed. If you install Proxmox Backup Server on top of Debian, download and install the key with the following commands: .. code-block:: console # wget http://download.proxmox.com/debian/proxmox-ve-release-6.x.gpg -O /etc/apt/trusted.gpg.d/proxmox-ve-release-6.x.gpg Verify the SHA512 checksum afterwards with: .. code-block:: console # sha512sum /etc/apt/trusted.gpg.d/proxmox-ve-release-6.x.gpg The output should be: .. code-block:: console acca6f416917e8e11490a08a1e2842d500b3a5d9f322c6319db0927b2901c3eae23cfb5cd5df6facf2b57399d3cfa52ad7769ebdd75d9b204549ca147da52626 /etc/apt/trusted.gpg.d/proxmox-ve-release-6.x.gpg and the md5sum: .. code-block:: console # md5sum /etc/apt/trusted.gpg.d/proxmox-ve-release-6.x.gpg Here, the output should be: .. code-block:: console f3f6c5a3a67baf38ad178e5ff1ee270c /etc/apt/trusted.gpg.d/proxmox-ve-release-6.x.gpg .. _sysadmin_package_repos_enterprise: `Proxmox Backup`_ Enterprise Repository ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This is the stable, recommended repository. It is available for all `Proxmox Backup`_ subscription users. It contains the most stable packages, and is suitable for production use. The ``pbs-enterprise`` repository is enabled by default: .. code-block:: sources.list :caption: File: ``/etc/apt/sources.list.d/pbs-enterprise.list`` deb https://enterprise.proxmox.com/debian/pbs buster pbs-enterprise To never miss important security fixes, the superuser (``root@pam`` user) is notified via email about new packages as soon as they are available. The change-log and details of each package can be viewed in the GUI (if available). Please note that you need a valid subscription key to access this repository. More information regarding subscription levels and pricing can be found at https://www.proxmox.com/en/proxmox-backup-server/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 you do not have a subscription key. Please configure the ``pbs-no-subscription`` repository in that case. `Proxmox Backup`_ 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 is not recommended to use it on production servers, because these packages are not always heavily tested and validated. We recommend to configure this repository in ``/etc/apt/sources.list``. .. code-block:: sources.list :caption: File: ``/etc/apt/sources.list`` deb http://ftp.debian.org/debian buster main contrib deb http://ftp.debian.org/debian buster-updates main contrib # PBS pbs-no-subscription repository provided by proxmox.com, # NOT recommended for production use deb http://download.proxmox.com/debian/pbs buster pbs-no-subscription # security updates deb http://security.debian.org/debian-security buster/updates main contrib `Proxmox Backup`_ Test Repository ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This repository contains the latest packages and is heavily used by developers to test new features. .. .. warning:: the ``pbstest`` repository should (as the name implies) only be used to test new features or bug fixes. You can access this repository by adding the following line to ``/etc/apt/sources.list``: .. code-block:: sources.list :caption: sources.list entry for ``pbstest`` deb http://download.proxmox.com/debian/pbs buster pbstest .. _package_repositories_client_only: Proxmox Backup Client-only Repository ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ If you want to :ref:`use the the Proxmox Backup Client ` on systems using a Linux distribution not based on Proxmox projects, you can use the client-only repository. Currently there's only a client-repository for APT based systems. .. _package_repositories_client_only_apt: APT-based Proxmox Backup Client Repository ++++++++++++++++++++++++++++++++++++++++++ For modern Linux distributions using `apt` as package manager, like all Debian and Ubuntu Derivative do, you may be able to use the APT-based repository. This repository is tested with: - Debian Buster - Ubuntu 20.04 LTS It may work with older, and should work with more recent released versions. In order to configure this repository you need to first :ref:`setup the Proxmox release key `. After that, add the repository URL to the APT sources lists. Edit the file ``/etc/apt/sources.list.d/pbs-client.list`` and add the following snipped .. code-block:: sources.list :caption: File: ``/etc/apt/sources.list`` deb http://download.proxmox.com/debian/pbs-client buster main .. _node_options_http_proxy: Repository Access Behind HTTP Proxy ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Some setups have restricted access to the internet, sometimes only through a central proxy. You can setup a HTTP proxy through the Proxmox Backup Server's web-interface in the `Configuration -> Authentication` tab. Once configured this proxy will be used for apt network requests and for checking a Proxmox Backup Server support subscription. Standard HTTP proxy configurations are accepted, `[http://][:port]` where the `` part may include an authorization, for example: `http://user:pass@proxy.example.org:12345`
