ValueError: not enough values to unpack (expected 2, got 0)

^ error https://pastebin.com/P7SFZdHY This happens which I use a certain iso, presumably because of the storage used for the iso. Anyways, I dont have anything more to add beside my error and the logs. This should be reproducable with nixmoxer and my config.
