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 inside '/etc/apt/sources.d/'. Updates can be installed directly using 'apt-get', or via the GUI.
Apt 'sources.list' files lists 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-get update'.
deb http://ftp.debian.org/debian jessie main contrib # security updates deb http://security.debian.org jessie/updates main contrib
In addition, {pve} provides three different package repositories.
This is the default, stable and recommended repository, available for
all {pve} subscription users. It contains the most stable packages,
and is suitable for production use. You need a valid subscription key
to access this repository. The pve-enterprise repository is enabled
by default:
deb https://enterprise.proxmox.com/debian jessie pve-enterprise
|
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
pve-no-subscription repository in that case.

As soon as updates are available, the root@pam user is notified via
email about the available new packages. On the GUI, the change-log of
each package can be viewed (if available), showing all details of the
update. So you will never miss important security fixes.
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. Its not recommended to run on production servers, as these packages are not always heavily tested and validated.
We recommend to configure this repository in '/etc/apt/sources.list'.
deb http://ftp.debian.org/debian jessie main contrib # PVE pve-no-subscription repository provided by proxmox.com, # NOT recommended for production use deb http://download.proxmox.com/debian jessie pve-no-subscription # security updates deb http://security.debian.org jessie/updates main contrib
Finally, there is a repository called pvetest. This one contains the
latest packages and is heavily used by developers to test new
features. As usual, you can configure this using
'/etc/apt/sources.list' by adding the following line:
pvetestdeb http://download.proxmox.com/debian jessie pvetest
