Dell ThinOS Update over WMS fails - Package Root failed to install
we just started using ThinOS Clients (Wyse 3040 & Optiplex 3000).
I´ve installed Dell WMS to manage the Thin Clients, and now I tried to Upgrade the ThinOS version from 9.3.1129 to 9.4.3087 with the help of a ThinOS 9.x Policy and the Image "ThinOS_2308_9.4.3087.pkg-V9.4.3087".
When I apply the policy the clients do download the firmware, however they always fail to install them.
The Error Message in WMS is: Generic Audit event received from XX- Package Root failed to install
Error Message on the Client: wms: failed to install package: JSON.stringify(error)
Do you have any idea how I could troubleshoot or solve the problem?
