Restore from backup failure

Got a weird issue trying to restore from a backup (as part of trying to solve this: Resolved: Still struggling with Let's Encrypt auto-renewal):

gpg: decryption failed: bad key

Now I tested the restore about a week ago in a local VM without any dramas - yet the restore today (with the same secret key) is telling me I’ve got a bad key. Is this likely a corrupt backup? Or is there something else that might have caused this?


Update: simple typo on my part - fixed. :smiley:
