I've been trying to create a Tails USB with persistence. According to their documentation I manually created the first Tails USB stick using the Pendrive Universal USB installer as the recommended. This USB stick works fine. When I use the Tails USB Installer from this stick to clone Tails to the new one as they describe, the operation repeatedly fails. I've tried 2 USB sticks for this, a 4 and an 8GB, both reset per their instructions. This is copied from their installer on the last attempt with the 8GB stick: Am I overlooking something or is there a problem with their installer or their instructions?
