"Wrong Key!" error on starting array after upgrading to 6.8 in Stable Releases Posted January 15 32 minutes ago, limetech said: If you are using some kind of mechanism to fetch a keyfile from an external server during the Unraid boot process, e.g., via the 'go' file, and that operation fails and leaves an invalid or zero-length keyfile, you will also get 'wrong key' even if you type the passphrase. This will be addressed in the next patch release 6.8.2. This was the problem for me. I've tried to fetch the keyfile from an FTP server by using spaceinvaderone's video, but couldn't get it to work, but never bothered to remove the code in the 'go' file. Removed it and it worked like a charm!
