sha3-384 mismatch

[Bret A. Barker]

Assuming you were hitting this error with a snapd prior to 2.18, then I think Madper is correct. Prior to 2.18 the order of the parameters for "got %s but expected %" was backward, see:
  https://github.com/snapcore/snapd/blob/release/2.17/store/store.go#L1155

And fixed in:
  https://github.com/snapcore/snapd/blob/release/2.18/store/store.go#L1378
