I've got the error message: "Operation failed (Code: 500)! Message: cannot install snap file: snap is unusable due to bad permissions; contact developer, Kind:" when I try to install the datalayer.client snap from the SDK on my ctrlX CORE.
I'm working with the SDK version 1.6.1 and as my development enviroment i'm using a WSL (Ubuntu 18.04). To build the snap I used "Release" and my Selected BuildKit is: "GCC for aarch64-linux-gnu 7.4.0" and Platformname is: "linux-gcc-aarch64". Prior to installing the snap I copied it from the WSL to my /C: drive under windows via cp-comand.
Note: I also allowed to install from unkown source and installed registernode on the ctrlX CORE first.
I checked this with our R&D and we could reproduced the problem and are looking for the reason. I will reply as soon as there are news.
