Debian Package Repositories
---------------------------

All Debian based systems use APT_ as package management tool. The list of
repositories is defined in ``/etc/apt/sources.list`` and ``.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

  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 repositories from Proxmox to get the backup
server updates.

During the Proxmox Backup beta phase only one repository (pbstest) will be
available. Once released, a Enterprise repository for production use and a
no-subscription repository will be provided.

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 key for
verification 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

    `Proxmox Backup`_ Enterprise Repository
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    This will be the default, stable, and 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:

    .. note:: During the Proxmox Backup beta phase only one repository (pbstest)
     will be available.

    .. 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/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`_ Beta Repository
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

During the public beta, there is a repository called ``pbstest``. This one
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 configure this using ``/etc/apt/sources.list`` by adding the following
line:

.. code-block:: sources.list
  :caption: sources.list entry for ``pbstest``

  deb http://download.proxmox.com/debian/pbs buster pbstest

If you installed Proxmox Backup Server from the official beta ISO you should
have this repository already configured in
``/etc/apt/sources.list.d/pbstest-beta.list``
