TESTDRIVE stuck with LICENSE Agreement SCREEN

Hello everyone,

I have built an appliance based on the SLES 12 SP1 and am trying to testdrive it, but I get stuck with the License agreement screen and cannot get over. I have found this old thread in the openSUSE forum, but even pressing Y and subsequently ENTER does not work.

Can anybody help, please? :confused:
