ZENworks Primary Server Upgrade fails with: Error occurred while importing the update into zone.

• Upgrading the first Primary server with an ISO
• Extracted the ZENworks ISO image to the file system of the Primary server with 7-Zip (7zip) or other tool
• The upgrade or install was run from the extracted media or
• The zman sui command was run to import the update from the extracted media
  or
• Install from a mounted ISO or burned CD that failed to properly mount the file system due to media "too big" to mount or burn.

If the upgrade was run from the extracted media, the following error could be seen in the ZENworks_Upgrade_<date>_<time>.log.xml:

ERROR:
Failed to import System Update. Check system update import log for more details.
Error occurred while importing the update into zone. Check the system-update-import.log in the logs directory for more details.

The following or similar could be seen in the system-update-import.log on a Linux primary server:

If the zman sui command was run to import the system update, the following error will be seen in ZCC (ZENworks Control Center):

ERROR:

From loader-messages.log:

In either case mentioned above, do the following:

1. Delete the extracted media from the file system of the Primary server
2. Delete the partially imported system update if it exists:
   zman sudu -f <system-update-name>
   ex: zman sudu -f "Update for ZENworks 11 SP4"
   
3. Burn the ZENworks ISO image to a DVD
   NOTE: If the DVD is too large, use a dual layer DVD and burner
   
4. Run the upgrade/install or zman sui command from the mounted DVD media

Please refer to the ZENworks Server Installation Guide for more details.

It is not supported to extract the ZENworks media to the file system of the server. Please see the note on burning the ZENworks ISO image to a DVD in Installation Workflow for Your First Primary Server and Installation Workflow for Additional Primary Servers.

In one particular case, 7-Zip failed to extract at least one of the files from the media.
