Hi Pegenaute,

In fact I'm meeting this issue every day before I setup a proxy...
May I know if you can reproduce it? And if so, did you get different
sha3-384 every time?

I think it's more like a network issue. The downloading interrupted somehow
so you got an incomplete snap pkg file. Which lead to a wrong sha result.

BR,
Madper
