Menu path: Setup > System > Update > Buddy Update
Under Buddy Update, you can specify your thin client as an update server for other IGEL thin clients. If you use a thin client as an update server, only the FTP protocol can be used to update the firmware. A number of thin clients can be set up as buddy update servers within the network.
Thin clients without a specified update server search for available servers during the update. The first update server contacted then provides the update.
The minimal requirement for using the functionality with IGEL OS 11 is 4 GB storage. A device with less than 4 GB storage can run IGEL OS 11 with a reduced feature set but will malfunction when configured as a Buddy Update server.
No Downgrade from IGEL OS 11.03
It is not possible to downgrade from IGEL OS 11.03 or higher to any version before IGEL OS 11.03, except IGEL OS 11.02.200. This is because, from IGEL OS 11.03 onwards, the system partitions are signed to guarantee their integrity; it is not possible to change from a system with signed partitions to a system with unsigned partitions. IGEL OS 11.02.200 is a special variant of IGEL OS 11.02 that has signed system partitions. IGEL OS 11.02.200 is only available from the IGEL Support Team.
Update Can Be Canceled After Timeout
An ongoing update can be canceled by the user if the "network online" status could not be reached within 10 seconds after the firmware update has been started. When the user has canceled the update, the normal desktop environment is started, just as before the update. This applies to the following cases:
- Regular firmware update, e.g. from IGEL OS 11.03.500 to IGEL OS 11.04
- A feature has been activated, e.g. VPN OpenConnect.
- A Custom Partition has been activated or changed.
- Enable Update Server
