10.8. Procedure – Updating and upgrading your Zorp hosts

Zorp uses the apt package manager application to keep the system up-to-date. Security and maintenance updates as well as product upgrades are all performed with apt. To update any host of your Zorp Firewall solution (including Zorp firewall hosts, ZAS and ZCV hosts, as well as your ZMS server), complete the following steps.

For more information on apt, see the apt-get manual page.

1. Update the apt sources of the host. Use one of the following methods:

   • To upgrade from a DVD-ROM:

     1. Open the Balasys website. To open it, it is necessary to authenticate with your support user credentials.

     2. Choose the necessary, preferably the latest version of the ISO file, and download it from the relevant cd directory.

     3. Burn the DVD-ROM to physical media.

     4. Mount the DVD-ROM on the host, and execute the following command as root: >:~#apt-cdrom add

   • To upgrade from the official Balasys apt repositories from the Internet:

     1. Edit the /etc/apt/sources.list.d/zorp.list file and add the URLs of the package sources to download.

   For details on the required sources, see Procedure 4.2, Upgrading Zorp hosts using apt in Zorp Professional 7 Installation Guide.

   Warning
   Do not remove Ubuntu sources from the /etc/apt/sources.list file. These are necessary for upgrading the base operating system.

2. Enter the following two commands.

   >:~#apt update

   >:~#apt dist-upgrade

   The first command updates the package list with the latest available versions. The second command performs the upgrade itself.

3. The rest of the process is done automatically.
