Thanks! I switched to the sign command last week, and it looks like it is working ok.
Another thing: Are there any documentation describing how to upgrade to the newest versions (mender 2 and mender-artifact 3)? When I have built a version 3 mender artifact, this isn’t compatible with Mender 1.6.x / mender-artifact 2.3.x (which is on my device right now), so I cannot upload this to my device. I guess I have to build a version 2 artifact which is including mender 2 and mender-artifact 3, and after uploading this, I can upload version 3 artifacts. Is this correct?
