4.2. Procedure – Upgrading PNS hosts using apt

Purpose: 

All the components of PNS can be upgraded using the standard apt tools. When used on Debian GNU/Linux systems, the Management Console (MC) and Authentication Agent (AA) client-side applications can be upgraded using apt as well. On Microsoft Windows and other Linux platforms, upgrades to these applications must be downloaded manually from BalaSys downloads. To perform an upgrade, complete the following steps.

Prerequisites: 

You will need a BalaSys Support System technical account to perform the upgrade. You can register a technical account by sending an email to <sales@balasys.hu> with the following personal data:

Make sure to remember your technical account credentials, because you will be asked to enter them during the installation of any PNS component. Later, the APT configuration file /etc/apt/auth.conf is generated automatically using these credentials.

After registering an account, send an email with the subject REQUESTING ACCESS TO PNS UPGRADES to <sales@balasys.hu> so that you receive the user rights required for downloading software updates.

Steps: 

1. Login to the host locally, or remotely using SSH.

2. Issue the following commands: apt update; apt -u dist-upgrade. The host will download and install the new and updated packages.

   Note
   If for any reason you do not want to install new packages, use the apt update; apt -u upgrade command. That way packages are only upgraded, new packages are not installed. Dependencies that are not installed are listed in the output of the command as kept back packages. (Such packages can be installed by issuing the apt -u dist-update command).
