During the update process, the following error messages are shown:


  • IGEL OS 11.03 or higher


The system expects signed system partitions, but the partitions of the update source are not signed. This will occur when you have tried to downgrade from IGEL OS 11.03 or higher to an older version of IGEL OS 11. 


 If you want to downgrade from IGEL OS 11.03 to IGEL OS 11.02, e. g. because you need certain older client versions, set the update source to IGEL OS 11.02.200.

IGEL OS 11.02.200 is a special variant of IGEL OS 11.02 which has signed partitions; this version can only be obtained from the IGEL Support Team.
