When a Dockerized App is selected for installation the Appcenter should check if the running Kernel is at least the UCS 4.1-0 Kernel, otherwise the App-Installation will fail. If the condition is not fulfilled, the Appcenter should block the installation with an informative message encouraging to reboot the UCS server. See Bug #39418 for details.
