SailfishOS upgrade error

gistfile1.txt

The upgrade goes fine and "show details" shows the following (I truncated some rows):

Downloading packages...
Downloading archive hash for ...
Downloading archive for component ...

Installing component SailfishOS emulator
/Users/nicd/SailfishOS/emulator/sailfishos.vdi
/Users/nicd/SailfishOS/emulator



After that I get an error saying the following and with the options ignore, cancel, retry:
Error during installation process (org.merproject.emulator):
Execution failed(Unexpected exit code: 1): "/usr/bin/VBoxManage createvm --name SailfishOS Emulator --register --basefolder /Users/nicd/SailfishOS/emulator"

Retrying doesn't work.



I tried running the command in the terminal in /Users/nicd/SailfishOS with the following results:
