yes, i was waiting for the first reboot, but i still get the error.
So here the steps i did:
1. Flash image through the installer you provide
2. start the cubox
3. wait until the first reboot is done and the ssh key and so on are generated.
4. after the second boot login with the root account
5. get the screen to change the password
6. type in my new password and get the Authentication token manipulation error
I also tried to reboot it again after the second boot, but it doesn't work
Will try another image from you
EDIT: Tried all latest images from you, wheezy, jessie and the ubuntu 14.04 image. I getting the same error on all images
