4.1. Procedure – Updating a host to the latest Zorp 6 version

Purpose: 

Upgrading to Zorp 7 is supported only from official Zorp 6 systems. The system must be up-to-date.

To update a Zorp host to the latest version of Zorp 6, complete the following steps.

Steps: 

1. Login to the host from a local console or using SSH. After the login, become root by using the sudo su - or the su command.

2. Run the following command:

   apt update

   If the update is successful, run the following command:

   apt -u dist-upgrade

   The latest upgrades will be downloaded and installed. The result should state that there are no packages on the system that have to be updated or modified (that is, the last line of the output should be something like:

   0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded

3. Optional step: To remove the hold flag from packages, complete the following steps:

   1. Issue the following command to find the packages on hold: dpkg --get-selections| grep hold > packagesonhold.txt

   2. Edit the packagesonhold.txt file (for example, using the joe packagesonhold.txt command) and change hold to install everywhere.

   3. Issue the following command as root: dpkg --set-selections<packagesonhold.txt
